    英語, 研究論文(学術雑誌), Dormancy is a crucial trait that allows land plants to withstand harsh terrestrial environments by pausing growth until favorable conditions return. The liverwort Marchantia polymorpha produces dormant propagules, gemmae, for asexual reproduction. The phytohormone abscisic acid (ABA) is known to regulate dormancy in the seeds of flowering plants and the gemmae of M. polymorpha. Here, we identify a basic helix-loop-helix protein, MpHYPNOS (MpHYP), as a central regulator of gemma dormancy. MpHYP expression induces germination arrest in gemmae. Transcriptome analysis revealed that MpHYP represses a D-type cyclin gene MpCYCD;1 and induces genes involved in ABA biosynthesis. Repression of MpCYCD;1 expression and germination arrest are both maintained even in an ABA-receptor mutant. By contrast, Mphyp and ABA-related mutants lacked the desiccation tolerance observed in wild-type gemmae. We propose that MpHYP regulates gemma dormancy through two parallel pathways: an ABA-independent pathway that suppresses germination through cell cycle repression, and an ABA-dependent pathway that enhances desiccation tolerance via ABA biosynthesis. These findings highlight an integrated regulatory mechanism of dormancy via phytohormonal and cell cycle control in bryophytes.

    研究論文(学術雑誌), Abstract

    Many herbs and spices have been reported to exhibit various biological activities, including antioxidant effects, antimicrobial activity, and antitumor activity; consequently, they are expected to contain novel bioactive compounds. In this study, anti-obesity agents were identified in several herbs and spices by screening for inhibitors of lipase, a key enzyme involved in lipid digestion. The extract of Origanum vulgare (oregano) demonstrated considerable lipase inhibitory activity. The active constituents from this plant were isolated by subjecting the oregano extract to several separation protocols, including SiO2 gel column chromatography and reversed-phase high-performance liquid chromatography. The purification process was guided by lipase inhibitory activity, affording origanone A (1) and origanone B (2) as novel abietane diterpenes. Notably, these compounds exhibited moderate lipase inhibitory activity. These findings indicate the potential of oregano and its active constituents as functional food ingredients for regulating lipid levels and obesity.

    Bioscience, biotechnology, and biochemistry, 2026年01月19日, [国際誌]
    英語, 研究論文(学術雑誌), Jasmonate is a plant hormone that regulates development and defense responses. Jasmonoyl-L-isoleucine (JA-Ile) is a ligand for the most studied jasmonate co-receptor, COI1-JAZ, in seed plants. 12-Oxygenation to 12-hydroxyjasmonoyl-L-isoleucine (12-OH-JA-Ile) is a major metabolic pathway of JA-Ile. Moreover, 12-OH-JA-Ile is a selective ligand for some COI1-JAZ pairs in Arabidopsis thaliana. However, few studies have reported on the activity of 12-OH-JA-Ile in rice (Oryza sativa L.). In this study, we synthesized 12-OH-JA-Ile and its isomers, and evaluated their biological activities against rice. 12-OH-JA-Ile inhibited root elongation but did not induce the biosynthesis of momilactone A, a phytoalexin. These results suggested that 12-OH-JA-Ile selectively induced a jasmonate response in rice. The bioactivity of the E-isomer of 12-OH-JA-Ile revealed that the Z-olefin was necessary for root inhibitory activity.

  • (3R, 7S)-11-hydroxy-jasmonic acid is a major oxidative shunt product of jasmonic acid catabolism in Arabidopsis thaliana

    Abstract

    Jasmonoyl-L-isoleucine (JA-Ile) is a pivotal oxylipin hormone that coordinates growth-defense trade-offs, and its precursor jasmonic acid (JA) is therefore subject to tight metabolic control. For more than a decade, the prevailing dogma held that jasmonate turnover is dominated by C12-hydroxylation, with JOX dioxygenases acting on JA and CYP94 monooxygenases acting on JA-Ile. Here we revise this dogma by showing that hydroxylation at the C11 position constitutes a major receptor-silent deactivation shunt of JA turnover.Using chemically synthesized (3R,7S)-11-hydroxy-JA (11-OH-JA) of naturally occurring stereochemistry as a standard, we unambiguously identify 11-OH-JA as the principal shunt product that accumulates in wounded Arabidopsis thaliana. In vitro enzymatic assays and in silico docking revealed that JOX1/2/3/4 exclusively converted JA to 11-OH-JA, whereas 12-OH-JA arose from distinct pathway. Consistently, the jox quadruple mutant (joxQ) abolished 11-OH-JA accumulation without affecting 12-OH-JA levels. Moreover, 11-OH-JA failed to bind the COI1–JAZ co-receptor, establishing it as a biologically inactive endpoint of JA catabolism.These findings correct a long-standing misattribution of the JOX product to 12-OH-JA and redefine the metabolic framework of jasmonate. Parallel, non-redundant inactivation routes deliver layered signal termination of costly defense signals. This study provides new insights into JA catabolism, highlighting 11-OH-JA as a crucial factor in the attenuation of jasmonate signaling, and thereby redefining the framework of JA turnover in A. thaliana.

  • Investigating Biologically Active Compounds from the Filamentous Fungi Bjerkandera adusta and Irpex lacteus That Inhibit the Growth of Marchantia polymorpha
    Vera Fitriya Ersalena; Akari Tada; Shiro Inoue; Naoki Kitaoka; Hideyuki Matsuura
    Natural Product Communications, 20, 10, SAGE Publications, 2025年10月09日
    研究論文(学術雑誌), Background

    Marchantia polymorpha is a model organism for research on evolutionary molecular-microbe interactions. Filamentous fungi pathogenic to M. polymorpha have been reported and a necrotrophic-like infection process has been proposed according to experiments conducted in the laboratory, but many aspects of M. polymorpha and microbes interaction remain unknown.

    Objective

    Field observations have been done and indicated that several kinds of fungi had ability to infect M. polymorpha and among of them, Bjerkandera adusta and Irpex lacteus infect M. polymorpha , and laboratory experiments have revealed that these fungi have a strong ability to infect M. polymorpha . Therefore, it was hypothesized that these fungi may produce specialized metabolites that lead to effectively invade into the liverwort. The aim of this research was to determine the chemical structures of the specialized metabolites and evaluate the biological activities of the compounds.

    Materials and Methods

    B. adusta and I. lacteus were obtained from GenBank Project, NARO. Male accessions of M. polymorpha, Takaragaike-1, were used for bioassay. The fungi were grown in potato dextrose broth medium. The culture filtrates were filtered and concentrated, and EtOAc (3 L) and H 2 O (1 L) were added to the crude material. Crude extracts obtained from the EtOAc were subjected to several kinds of purification steps to afford methyl vanillin from B. adusta and tremutin E from I. lacteus .

    Results

    Methyl vanillin and tremutin E were isolated from B. adusta and I. lacteus , respectively, according to a guidance of growth inhibitory activity-guided fractionations and identified using mass spectroscopic data together with 1D and 2D NMR techniques.

    Conclusion

    Methyl vanillin and tremutin E inhibited the growth of M. polymorpha with almost 100-fold stronger activity than that of acetic acid, a pivotal active ingredient of commercial anti-liverwort agent.

    英語, 研究論文(学術雑誌), Jasmonates are plant hormones that regulate plant defense and development. 7-iso-Jasmonoyl-l-isoleucine (JA-Ile) is a representative active jasmonate which is biosynthesized from 7-iso-jasmonic acid (JA) by the jasmonoyl-amido synthases JASMONATE RESISTANT 1 (JAR1) and AtGH3.10 in Arabidopsis thaliana. 12-Hydroxy-7-iso-jasmonoyl-l-isoleucine (12-OH-JA-Ile) is another active jasmonate, and 12-hydroxylation of JA-Ile is considered the major biosynthetic pathway toward 12-OH-JA-Ile. Previous report elucidated that recombinant JAR1 showed a weak activity against 12-hydroxy-7-iso-jasmonic acid (12-OH-JA). However, the direct conversion from 12-OH-JA to 12-OH-JA-Ile in planta and the enzyme activity of AtG3.10 against 12-OH-JA have never been reported. Herein, a feeding experiment with deuterated 12-OH-JA confirms the direct conversion of 12-OH-JA to 12-OH-JA-Ile in wild-type Arabidopsis plants. The conversion from 12-OH-JA to 12-OH-JA-Ile is not observed in jar1 gh3.10 double mutant, suggesting that 12-OH-JA is converted to 12-OH-JA-Ile by JAR1 and AtGH3.10. Notably, enzyme assays show that the catalytic efficiency with 12-OH-JA for AtGH3.10 is higher than those with JA for AtGH3.10 and with 12-OH-JA for JAR1. Comparative analysis of JAR1 and AtGH3.10 structures and site-directed mutation analysis reveals that Ser120 in AtGH3.10 is the key amino acid residue responsible for its high catalytic efficiency against 12-OH-JA.

    英語, 研究論文(学術雑誌), There is no existing evidence of the existence of jasmonates and (+)-7-iso-Jasmonoyl-ʟ-isoleucine (JA-l-Ile) in Bryophytes. Mosses belong to Bryophytes, and it was found that 3 kinds of mosses, Calohypnum plumiforme, Lencobryum bowringii, and Pyrrhobryum dozyanum, accumulated detectable levels of endogenous JA-l-Ile in the aerial parts, but not in Bartramia pomiformis belonging to the same plant group.

    英語, 研究論文(学術雑誌), Maillard reaction products (MRPs) of xylose with phenylalanine and xylose with proline exhibit high antibacterial activity. However, the active antibacterial compounds in MRPs have not yet been identified or isolated. This study aimed to isolate the active compounds in the two antibacterial MRPs. The organic layer of the MRP solution was separated and purified using silica gel chromatography and high-performance liquid chromatography. The chemical structures of the isolated compounds were determined by mass spectrometry and nuclear magnetic resonance spectroscopy. The compounds inhibited the growth of Bacillus cereus and Salmonella Typhimurium at 25 °C for 7 days at a concentration of 0.25 mM. Furthermore, the isolated compounds inhibited the growth of naturally occurring microflora of lettuce and chicken thighs at 25 °C for 2 days at a concentration of 0.5-1.0 mM. The antibacterial compounds found in MRPs demonstrated a wide range of effectiveness and indicated their potential as alternative preservatives.

    英語, 研究論文(学術雑誌), cis-12-oxo-Phytodieneoic acid-α-monoglyceride (1) was isolated from Arabidopsis thaliana. The chemical structure of 1 was elucidated based on exhaustive 1D and 2D NMR spectroscopic measurements and supported by FDMS and HRFDMS data. The absolute configuration of the cis-OPDA moiety in 1 was determined by comparison of 1H NMR spectra and ECD measurements. With respect to the absolute configuration of the β-position of the glycerol backbone, the 2:3 ratio of (S) to (R) was determined by making ester-bonded derivatives with (R)-(+)-α-methoxy-α-trifluoromethylphenylacetyl chloride and comparing 1H NMR spectra. Wounding stress did not increase endogenous levels of 1, and it was revealed 1 had an inhibitory effect of A. thaliana post germination growth. Notably, the endogenous amount of 1 was higher than the amounts of (+)-7-iso-jasmonic acid and (+)-cis-OPDA in intact plants. 1 also showed antimicrobial activity against Gram-positive bacteria, but jasmonic acid did not. It was also found that α-linolenic acid-α-monoglyceride was converted into 1 in the A. thaliana plant, which implied α-linolenic acid-α-monoglyceride was a biosynthetic intermediate of 1.

    英語, 研究論文(学術雑誌), A novel isocoumarin was isolated from the mycelia of the dark septate endophytic fungus Phialocephala fortinii. The chemical structure was determined to be 8-hydroxy-6-methoxy-3,7-dimethyl-1H-2-benzopyran-1-one based on mass spectrometry, 1H-nuclear magnetic resonance (NMR), and 13C-NMR spectroscopic analyses, including 2D-NMR experiments. The isolated compound inhibited root growth of Arabidopsis thaliana, suggesting its potential as a plant growth regulator.

    Chembiochem : a European journal of chemical biology, e202300593, 2023年11月07日, [国際誌]
    英語, 研究論文(学術雑誌), Researchers have established that (+)-7-iso-jasmonic acid ((+)-7-iso-JA) is an intermediate in the production of cis-jasmone (CJ); however, the biosynthetic pathway of CJ has not been fully described. Previous reports stated that CJ, a substructure of pyrethrin II produced by pyrethrum (Tanacetum cinerariifolium), is not biosynthesized through this biosynthetic pathway. To clarify the ambiguity, stable isotope-labelled jasmonates were synthesized, and compounds were applied to apple mint (Mentha suaveolens) via air propagation. The results showed that cis-jasmone is not generated from intermediate (+)-7-iso-JA, and (+)-7-iso-JA is not produced from 3,7-dideydro-JA (3,7-ddh-JA); however, 3,7-didehydro-JA and 4,5-didehydro-7-iso-JA were converted into CJ and JA, respectively.

  • Pennelliiside D, a New Acyl Glucose from Solanum pennellii and Chemical Synthesis of Pennelliisides
    Rishni Masimbula; Hiroto Kobayashi; Tenki Nakashima; Yurika Nambu; Naoki Kitaoka; Hideyuki Matsuura
    Molecules, 27, 12, 2022年06月09日, [国際誌]
    英語, 研究論文(学術雑誌), Acyl glucoses are a group of specialized metabolites produced by Solanaceae. Solanum pennellii, a wild-type tomato plant, produces acyl glucoses in its hair-like epidermal structures known as trichomes. These compounds have been found to be herbicides, microbial growth inhibitors, or allelopathic compounds. However, there are a few reports regarding isolation and investigation of biological activities of acyl glucoses in its pure form due to the difficulty of isolation. Here, we report a new acyl glucose, pennelliiside D, isolated and identified from S. pennellii. Its structure was determined by 1D NMR and 2D NMR, together with FD-MS analysis. To clarify the absolute configuration of the acyl moiety of 2-methylbutyryl in the natural compound, two possible isomers were synthesized starting from β-D-glucose pentaacetate. By comparing the spectroscopic data of natural and synthesized compounds of isomers, the structure of pennelliiside D was confirmed to be 3,4-O-diisobutyryl-2-O-((S)-2-methylbutyryl)-D-glucose. Pennelliiside D and its constituent fatty acid moiety, (S)-2-methylbutanoic acid, did not show root growth-inhibitory activity. Additionally, in this study, chemical synthesis pathways toward pennelliisides A and B were adapted to give 1,6-O-dibenzylpennelliisides A and B.

    英語, 研究論文(学術雑誌), Quercetin, a flavonol, is a functional compound that is abundant in onions and is known to have antioxidant and anti-inflammatory effects. Quercetin and its glucoside are known to function as peroxisome proliferator-activated receptor (PPAR) ligands and showed high PPAR-α transactivation activity but little PPAR-γ transactivation activity in some reports. In this study, we demonstrated that an aqueous extract of a quercetin-rich onion cultivar increased transactivation activities not only of PPAR-α but also of PPAR-γ. We isolated (9S,12S,13S)-(10E)-9,12,13-trihydroxyoctadec-10-enoic acid (pinellic acid) obtained from the aqueous extract using PPAR-γ transactivation as an index. Furthermore, it was revealed that pinellic acid could transactivate PPAR-α. Our findings are the first report mentioned showing that trihydroxyoctadec-10-enoic acids showed PPAR-α/γ transactivation activities.
  • AtGH3.10 is another jasmonic acid-amido synthetase in Arabidopsis thaliana.

    The Plant journal : for cell and molecular biology, 110, 4, 1082, 1096, 2022年03月04日, [国際誌]
    英語, 研究論文(学術雑誌), Jasmonoyl-isoleucine (JA-Ile) is a key signaling molecule that activates jasmonate-regulated flower development and the wound stress response. For years, JASMONATE RESISTANT1 (JAR1) has been the sole jasmonoyl-amino acid synthetase known to conjugate jasmonic acid (JA) to isoleucine, and the source of persisting JA-Ile in jar1 knockout mutants has remained elusive until now. Here we demonstrate through recombinant enzyme assays and loss-of-function mutant analyses that AtGH3.10 functions as a JA-amido synthetase. Recombinant AtGH3.10 could conjugate JA to isoleucine, alanine, leucine, methionine, and valine. The JA-Ile accumulation in the gh3.10-2 jar1-11 double mutant was nearly eliminated in the leaves and flower buds while its catabolism derivative 12OH-JA-Ile was undetected in the flower buds and unwounded leaves. Residual levels of JA-Ile, JA-Ala, and JA-Val were nonetheless detected in gh3.10-2 jar1-11, suggesting the activities of similar promiscuous enzymes. Upon wounding, the accumulation of JA-Ile and 12OH-JA-Ile and the expression of JA-responsive genes OXOPHYTODIENOIC ACID REDUCTASE3 and JASMONATE ZIM-DOMAIN1 observed in WT, gh3.10-1, and jar1-11 leaves were effectively abolished in gh3.10-2 jar1-11. Additionally, an increased proportion of undeveloped siliques associated with retarded stamen development was observed in gh3.10-2 jar1-11. These findings conclusively show that AtGH3.10 contributes to JA-amino acid biosynthesis and functions partially redundantly with AtJAR1 in sustaining flower development and the wound stress response in Arabidopsis.
  • Substrate specificity of glycoside hydrolase family 1 β-glucosidase AtBGlu42 from Arabidopsis thaliana and its molecular mechanism.

    英語, 研究論文(学術雑誌), Plants possess many glycoside hydrolase family 1 (GH1) β-glucosidases, which physiologically function in cell wall metabolism and activation of bioactive substances, but most remain uncharacterized. One GH1 isoenzyme AtBGlu42 in Arabidopsis thaliana has been identified to hydrolyze scopolin using the gene deficient plants, but no enzymatic properties were obtained. Its sequence similarity to another functionally characterized enzyme Os1BGlu4 in rice suggests that AtBGlu42 also acts on oligosaccharides. Here, we show that the recombinant AtBGlu42 possesses high kcat/Km not only on scopolin, but also on various β-glucosides, cellooligosaccharides, and laminarioligosaccharides. Of the cellooligosaccharides, cellotriose was the most preferred. The crystal structure, determined at 1.7 Å resolution, suggests that Arg342 gives unfavorable binding to cellooligosaccharides at subsite +3. The mutants R342Y and R342A showed the highest preference on cellotetraose or cellopentaose with increased affinities at subsite +3, indicating that the residues at this position have an important role for chain length specificity.

    英語, 研究論文(学術雑誌), Abscisic acid (ABA, 1) is a plant hormone that regulates various plant physiological processes such as seed developing and stress responses. The ABA signaling system has been elucidated; binding of ABA with PYL proteins triggers ABA signaling. We have previously reported a new method to isolate a protein targeted with a bioactive small molecule using a biotin linker with alkyne and amino groups, a protein cross-linker, and a bioactive small molecule with an azido group (azido probe). This method was used to identify the unknown ABA binding protein of Arabidopsis thaliana. As a result, AtTrxh3, a thioredoxin, was isolated as an ABA binding protein. Our developed method can be applied to the identification of binding proteins of bioactive compounds.

    英語, 研究論文(学術雑誌), Salicylic acid (SA) is a phytohormone that regulates a variety of physiological and developmental processes, including disease resistance. SA is a key signaling component in the immune response of many plant species. However, the mechanism underlying SA-mediated immunity is obscure in rice (Oryza sativa). Prior analysis revealed a correlation between basal SA level and blast resistance in a range of rice varieties. This suggested that resistance might be improved by increasing basal SA level. Here, we identified a novel UDP-glucosyltransferase gene, UGT74J1, which is expressed ubiquitously throughout plant development. Mutants of UGT74J1 generated by genome editing accumulated high levels of SA under non-stressed conditions, indicating that UGT74J1 is a key enzyme for SA homeostasis in rice. Microarray analysis revealed that the ugt74j1 mutants constitutively overexpressed a set of pathogenesis-related (PR) genes. An inoculation assay demonstrated that these mutants had increased resistance against rice blast, but they also exhibited stunted growth phenotypes. To our knowledge, this is the first report of a rice mutant displaying SA overaccumulation.

    英語, 研究論文(学術雑誌), Nitro groups are often associated with synthetically manufactured compounds such as medicines and explosives, and rarely with natural products. Loquat emits a nitro compound, (2-nitroethyl)benzene, as a flower scent. The nitro compound exhibits fungistatic activity and is biosynthesised from l-phenylalanine via (E/Z)-phenylacetaldoxime. Although aldoxime-producing CYP79s have been intensively studied, it is unclear what enzymes form nitro groups from aldoximes either in plants or in other organisms. Here, we report the identification of two cytochrome P450s that are likely to be involved in (2-nitroethyl)benzene biosynthesis in loquat through differential gene expression analysis using RNA-seq and functional identification using yeast and tobacco. CYP79D80 and CYP94A90 catalysed the formation of (E/Z)-phenylacetaldoxime from l-phenylalanine and (2-nitroethyl)benzene from the aldoxime, respectively. Expression profiles of CYP79D80 and CYP94A90 were correlated with the emission of (2-nitroethyl)benzene from loquat flowers. CYP94A90 also functioned as a fatty acid ω-hydroxylase as do other CYP94A fatty acid ω-hydroxylases. The CYP94As tested from other plants were all found to catalyse the formation of (2-nitroethyl)benzene from (E/Z)-phenylacetaldoxime. CYP79D80 and CYP94A90 are likely to operate in concert to biosynthesise (2-nitroethyl)benzene in loquat. CYP94A90 and other CYP94As are 'promiscuous fatty acid ω-hydroxylases', catalysing the formation of nitro groups from aldoximes, and are widely distributed in dicot plants.

    英語, 研究論文(学術雑誌), Jasmonic acid (JA) is a plant hormone involved in the defense response against insects and fungi. JA is synthesized from α-linolenic acid (LA) by the octadecanoid pathway in plants. 12-oxo-Phytodienoic acid (OPDA) is one of the biosynthetic intermediates in this pathway. The reported stereo selective total synthesis of cis-(+)-OPDA is not very efficient due to the many steps involved in the reaction as well as the use of water sensitive reactions. Therefore, we developed an enzymatic method for the synthesis of OPDA using acetone powder of flax seed and allene oxide cyclase (PpAOC2) from Physcomitrella patens. From this method, natural cis-(+)-OPDA can be synthesized in the high yield of approximately 40%. In this study, we investigated the substrate specificity of the enzymatic synthesis of other OPDA analogs with successions to afford OPDA amino acid conjugates, dinor-OPDA (dn-OPDA), and OPDA monoglyceride, and it was suggested that the biosynthetic pathway of arabidopsides could occur via MGDG.
  • Ozone disrupts the communication between plants and insects in urban and suburban areas: an updated insight on plant volatiles.

    英語, Plant-insect interactions are basic components of biodiversity conservation. To attain the international Sustainable Development Goals (SDGs), the interactions in urban and in suburban systems should be better understood to maintain the health of green infrastructure. The role of ground-level ozone (O3) as an environmental stress disrupting interaction webs is presented. Ozone mixing ratios in suburbs are usually higher than in the center of cities and may reduce photosynthetic productivity at a relatively higher degree. Consequently, carbon-based defense capacities of plants may be suppressed by elevated O3 more in the suburbs. However, contrary to this expectation, grazing damages by leaf beetles have been severe in some urban centers in comparison with the suburbs. To explain differences in grazing damages between urban areas and suburbs, the disruption of atmospheric communication signals by elevated O3 via changes in plant-regulated biogenic volatile organic compounds and long-chain fatty acids are considered. The ecological roles of plant volatiles and the effects of O3 from both a chemical and a biological perspective are presented. Ozone-disrupted plant volatiles should be considered to explain herbivory phenomena in urban and suburban systems.

    英語, 研究論文(学術雑誌), Symbiosis of Penicillium rolfsii Y-1 is essential for the seed germination of Hawaii yellow-eyed grass (Xyris complanata). However, the local soil where the plants grow naturally often suppresses the radicle growth of the seedlings. This radicle growth was drastically restored by coinoculation of Paraburkholderia phenazinium isolate CK-PC1, which is a rhizobacterium of X. complanata. It was found that the isolate CK-PC1 produced phenazine-1-carboxylic acid (PCA, 1) as a major metabolite. The biological effects of PCA (1) were investigated using the seeds of X. complanata and Mung bean (Vigna radiata) and it was uncovered that the symbiosis of the isolate CK-PC1was essential for the postgermination growth of X. complanata and the metabolite PCA (1) might partially contribute to promote the growth of the plants.

    英語, 研究論文(学術雑誌), Salicylic acid (SA) and methyl salicylate (MeSA) are synthesized in many plants and are crucial components that establish their disease responses. The metabolism of airborne MeSA to SA has been previously reported. In this report, it was found that SA glucose ester (SAGE), ether (SAG), and salicyloyl-L-aspartic acid (SA-Asp) are metabolites of airborne MeSA. Furthermore, it was found that airborne MeSA was able to increase the endogenous amount of rosmarinic acid in Perilla frutescens, which is known as one of the functional components that contributes to the maintenance of human health.

    英語, 研究論文(学術雑誌), Solanum species accumulate a variety of secondary metabolites in their trichomes, and it is well known that acyl sugars are specialized metabolites secreted by the trichomes. However, very few reports provide detailed information on the chemical structure of polyacylated glucose derivatives, due to the α and β isomerization that can occur at the C-1 position. In this study, a strategy was established to isolate polyacylated glucose derivatives. According to the developed strategy, hydroxy groups were derivatized to a benzyloxy group using TriBOT. After isolation of the compounds in pure form and deprotection of the benzyloxy group, the chemical structures of pennelliisides A-C were determined as 2,3,4-O-triisobutyryl-d-glucose, 3-O-(8-methylnonanoyl)-2,4-O-diisobutyryl-d-glucose, and 3-O-decanoyl-2,4-O-diisobutyryl-d-glucose, respectively. Structural elucidation was performed using spectroscopic techniques, including 1D and 2D NMR, FD-MS, and GC-MS. It was also found that the fatty acid moiety contributes to the allelopathic properties of the isolated compounds.

    英語, 研究論文(学術雑誌), Pyrethrum (Tanacetum cinerariifolium) produces insecticidal compounds known as pyrethrins. Pyrethrins are esters; the acid moiety is either trans-chrysanthemic acid or pyrethric acid and the alcohol moiety of pyrethrins is either pyrethrolone, cinerolone, or jasmolone. It was generally accepted that cis-jasmone was biosynthetic intermediate to produce the alcohol moieties of pyrethrin, and the biosynthetic origin of the cis-jasmone was postulated to be jasmonic acid. However, there was no direct evidence to prove this hypothesis. In order to uncover the origin of pyrethrolone moiety in pyrethrin II, feeding experiments were performed employing deuterium- and 13C-labeled compounds as substrates, and the expected labeled compounds were analyzed using UPLC MS/MS system. It was found that the pyrethrolone moiety in pyrethrin II was derived from 12-oxo-phytodienoic acid (OPDA), iso-OPDA and cis-jasmone but not from methyl jasmonate and 3-oxo-2-(2'-[Z]-pentenyl)-cyclopentane-1-hexanoic acid. The results supported that the biosynthesis of the pyrethrolone moiety in pyrethrin II partially used part of the jasmonic acid biosynthetic pathway, but not whole.

    英語, 研究論文(学術雑誌), Salicylic acid (SA), an essential secondary messenger for plant defence responses, plays a role in maintaining a balance (trade-off) between plant growth and resistance induction, but the detailed mechanism has not been explored. Because the SA mimic benzothiadiazole (BTH) is a more stable inducer of plant defence than SA after exogenous application, we analysed expression profiles of defence genes after BTH treatment to better understand SA-mediated immune induction. Transcript levels of the salicylic acid glucosyltransferase (SAGT) gene were significantly lower in BTH-treated Nicotiana tabacum (Nt) plants than in SA-treated Nt control plants, suggesting that SAGT may play an important role in SA-related host defence responses. Treatment with BTH followed by SA suppressed SAGT transcription, indicating that the inhibitory effect of BTH is not reversible. In addition, in BTH-treated Nt and Nicotiana benthamiana (Nb) plants, an early high accumulation of SA and SA 2-O-β-d-glucoside was only transient compared to the control. This observation agreed well with the finding that SAGT-overexpressing (OE) Nb lines contained less SA and jasmonic acid (JA) than in the Nb plants. When inoculated with a virus, the OE Nb plants showed more severe symptoms and accumulated higher levels of virus, while resistance increased in SAGT-silenced (IR) Nb plants. In addition, the IR plants restricted bacterial spread to the inoculated leaves. After the BTH treatment, OE Nb plants were slightly larger than the Nb plants. These results together indicate that SAGT has a pivotal role in the balance between plant growth and SA/JA-mediated defence for optimum plant fitness.

    英語, 研究論文(学術雑誌), BACKGROUND: Prenatal maternal exposure to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) has been reportedly associated with decreased birth weight. Although a majority of epidemiological studies concerning perfluoroalkyl substances (PFAS) have focused on PFOS and PFOA, epidemiological studies of PFAS with longer carbon chains are scarce. In this study, we investigated whether prenatal maternal exposure to 11 PFAS, in particular those with longer carbon chains, is associated with fetal growth. METHODS: The study included 1985 mother-infant pairs (inclusive of preterm and post-term infants), who enrolled in a large-scale, prospective birth cohort study in any of the 37 hospitals in Hokkaido, Japan between 2003 and 2009. The concentration of 11 PFAS was measured in maternal plasma collected during the third trimester of pregnancy, using ultra-performance liquid chromatography in combination with triple quadrupole mass spectrometry. Associations between the measured PFAS values and weight, length, and head circumference of all newborns at birth were examined using multiple regression analyses with adjustment for potential confounders based on data collected from medical records, questionnaires, and those for maternal plasma samples. RESULTS: Of the 11 PFAS analyzed, prenatal perfluorononanoic acid (PFNA) [per log10-unit: regression coefficient (β) = -96.2 g, 95% confidence intervals (95% CI), -165.3 to -27.1] and perfluorodecanoic acid (PFDA) (β = -72.2 g, 95% CI, -138.1 to -6.3) concentrations were inversely associated with birth weight. Furthermore, PFNA concentrations were inversely associated with birth length (per Log10 unit: β = -0.48 cm, 95% CI; - 0.86 to -0.11). Maternal perfluorotridecanoic acid (PFTrDA) exposure showed a significant inverse association with birth weight only for female infants (per Log10 unit: β = -99.8 g, 95% CI, - 193.7 to -6.0) (P for interaction = 0.04). CONCLUSIONS: Our findings suggest that prenatal, maternal exposure to PFAS with longer carbon chains tends to be inversely associated with birth size of newborn infants, which may indicate that these commercially used compounds have an adverse effect on fetal growth.

    International journal of molecular sciences, 21, 4, 2020年02月19日, [国際誌]
    英語, 研究論文(学術雑誌), Wounding is a serious environmental stress in plants. Oxylipins such as jasmonic acid play an important role in defense against wounding. Mechanisms to adapt to wounding have been investigated in vascular plants; however, those mechanisms in nonvascular plants remain elusive. To examine the response to wounding in Physcomitrella patens, a model moss, a proteomic analysis of wounded P. patens was conducted. Proteomic analysis showed that wounding increased the abundance of proteins related to protein synthesis, amino acid metabolism, protein folding, photosystem, glycolysis, and energy synthesis. 12-Oxo-phytodienoic acid (OPDA) was induced by wounding and inhibited growth. Therefore, OPDA is considered a signaling molecule in this plant. Proteomic analysis of a P. patens mutant in which the PpAOS1 and PpAOS2 genes, which are involved in OPDA biosynthesis, are disrupted showed accumulation of proteins involved in protein synthesis in response to wounding in a similar way to the wild-type plant. In contrast, the fold-changes of the proteins in the wild-type plant were significantly different from those in the aos mutant. This study suggests that PpAOS gene expression enhances photosynthesis and effective energy utilization in response to wounding in P. patens.
  • Does Ozone Alter the Attractiveness of Japanese White Birch Leaves to the Leaf Beetle Agelastica coerulea via Changes in Biogenic Volatile Organic Compounds (BVOCs): An Examination with the Y-Tube Test

    研究論文(学術雑誌), Elevated ground-level ozone (O3) reduced C-based defense chemicals; however, severe grazing damages were found in leaves grown in the low O3 condition of a free air O3-concentration enrichment (O3-FACE) system. To explain this phenomenon, this study investigates the role of BVOCs (biogenic volatile organic compounds) as signaling compounds for insect herbivores. BVOCs act as scents for herbivore insects to locate host plants, while some BVOCs show high reactivity to O3, inducing changes in the composition of BVOCs in atmospheres with elevated O3. To assess the aforementioned phenomenon, profiles of BVOCs emitted from birch (Betula platyphylla var. japonica Hara) leaves were analyzed ex situ, and Y-tube insect preference tests were conducted in vitro to study the insect olfactory response. The assays were conducted in June and August or September, according to the life cycle of the adult alder leaf beetle Agelastica coerulea Baly (Coleoptera: Chrysomelidae). The Y-tube tests revealed that the leaf beetles were attracted to BVOCs, and O3 per se had neither an attractant nor a repellent effect. BVOCs became less attractant when mixed with highly concentrated O3 (>80 ppb). About 20% of the total BVOCs emitted were highly O3-reactive compounds, such as β-ocimene. The results suggest that BVOCs emitted from the birch leaves can be altered by elevated O3, thus potentially reducing the attractiveness of leaves to herbivorous insects searching for food.

    英語, 研究論文(学術雑誌), Target protein identification of bioactive small molecules is one of the most important research in forward chemical genetics. The affinity chromatography technique to use a resin bound with a small molecule is often used for identification of a target protein of a bioactive small molecule. Here we report a new method to isolate a protein targeted with a bioactive small molecule using a biotin linker with alkyne and amino groups, protein cross-linker containing disulfide bond, and a bioactive small molecule with an azido group (azido probe). After an azido probe is associated with a target protein, the complex of a target protein and azido probe is covalently bound through the biotin linker by azide-alkyne Huisgen cycloaddition and protein cross-linker containing disulfide bond. This ternary complex is immobilized on an affinity matrix with streptavidin, and then the target protein is selectively eluted with a buffer containing a reducing agent for cleavage of disulfide bonds. This method uses a probe having an azido group, which a small functional group, and has the possibility to be a solution strategy to overcome the hindrance of a functional group introduced into the probe that reduces association a target protein. The effectiveness of the method in this study was shown using linker 1, 3'-azidoabscisic acid 3, and protein cross-linker containing a disulfide bond (DTSSP 5).

    英語, 研究論文(学術雑誌), 12-hydroxy-jasmonoyl-isoleucine (12OH-JA-Ile) is a metabolite in the catabolic pathway of the plant hormone jasmonate, and is synthesized by the cytochrome P450 subclade 94 enzymes. Contrary to the well-established function of jasmonoyl-isoleucine (JA-Ile) as the endogenous bioactive form of jasmonate, the function of 12OH-JA-Ile is unclear. Here, the potential role of 12OH-JA-Ile in jasmonate signaling and wound response was investigated. Exogenous application of 12OH-JA-Ile mimicked several JA-Ile effects including marker gene expression, anthocyanin accumulation and trichome induction in Arabidopsis thaliana. Genome-wide transcriptomics and untargeted metabolite analyses showed large overlaps between those affected by 12OH-JA-Ile and JA-Ile. 12OH-JA-Ile signaling was blocked by mutation in CORONATINE INSENSITIVE 1. Increased anthocyanin accumulation by 12OH-JA-Ile was additionally observed in tomato and sorghum, and was disrupted by the COI1 defect in tomato jai1 mutant. In silico ligand docking predicted that 12OH-JA-Ile can maintain many of the key interactions with COI1-JAZ1 residues identified earlier by crystal structure studies using JA-Ile as ligand. Genetic alternation of jasmonate metabolic pathways in Arabidopsis to deplete both JA-Ile and 12OH-JA-Ile displayed enhanced jasmonate deficient wound phenotypes and was more susceptible to insect herbivory than that depleted in only JA-Ile. Conversely, mutants overaccumulating 12OH-JA-Ile showed intensified wound responses compared with wild type with similar JA-Ile content. These data are indicative of 12OH-JA-Ile functioning as an active jasmonate signal and contributing to wound and defense response in higher plants.

    英語, 研究論文(学術雑誌), It has been reported that airborne methyl jasmonate (MeJA) was metabolized into jasmonic acid (JA) and jasmonoyl isoleucine (JA-L-Ile). In this report, jasmonoyl valine (JA-L-Val), 12-hydroxy JA (12OHJA), and 12-glucosyloxy JA (12OGlcJA) were identified as metabolites originating from airborne MeJA using tomato (Solanum lycopersicum). Furthermore, the preferable conversion of (-)-MeJA (natural form) into 12OHJA, 12OGlcJA, JA-L-Ile, and JA-L-Val was observed.

    英語, 研究論文(学術雑誌), Leaf color change through chlorophyll degradation is a characteristic symptom of senescence. Magnesium removal from chlorophyll a is the initial step in chlorophyll a degradation, in a reaction catalyzed by Stay-Green (SGR). Arabidopsis thaliana has three SGR homologs, SGR1, SGR2, and SGR-like. When SGR1 is overexpressed, both chlorophyll a and b are degraded and leaves turn yellow. This process is visually identical to senescence, suggesting that SGR1 overexpression affects various physiological processes in plants. To examine this possibility, gene expression associated with chlorophyll metabolism and senescence was analyzed following dexamethasone-inducible SGR1 introduction into Arabidopsis. When SGR1 was overexpressed following 18 h of dexamethasone treatment, genes involved in chlorophyll degradation were upregulated, as were senescence-associated genes. These observations suggested that chlorophyll a degradation promotes senescence. As jasmonate is the plant hormone responsible for senescence and was expected to be involved in the regulation of gene expression after dexamethasone treatment, the level of jasmonoyl-isoleucine, the active form of jasmonate, was measured. The jasmonoyl-isoleucine level increased slightly after 10 h of SGR1 overexpression, and this increase became significant after 18 h. These observations suggest that jasmonate is produced through chlorophyll a degradation and affects the promotion of senescence.

    英語, 研究論文(学術雑誌), Wounding stress induces the biosynthesis of various specialized metabolites in plants. In this study, wounding induced the biosynthesis of luteolin, apigenin, and isoriccardin C, which are biosynthesized through the phenylpropanoid pathway, in the model liverwort Marchantia polymorpha L (Marchantiaceae). Recombinant M. polymorpha phenylalanine ammonia lyases (MpPALs) exhibited PAL activity in vitro and converted phenylalanine into trans-cinnamic acid. Based on semi-quantitative RT-PCR analysis, the expression levels of the MpPAL genes were up-regulated after wounding. α-Aminooxy-β-phenylpropionic acid, a PAL inhibitor, suppressed the production of wounding-induced phenolic compounds, luteolin, apigenin, and isoriccardin C, in M. polymorpha. Thus, PAL is a committed step in the biosynthesis of phenylpropanoids in response to wounding in M. polymorpha. This study suggests that wound-induced specialized metabolites such as phenylpropanoids comprise a conserved defense system in land plants.

    英語, 研究論文(学術雑誌), Plant root systems are indispensable for water uptake, nutrient acquisition, and anchoring plants in the soil. Previous studies using auxin inhibitors definitively established that auxin plays a central role regulating root growth and development. Most auxin inhibitors affect all auxin signaling at the same time, which obscures an understanding of individual events. Here, we report that jasmonic acid (JA) functions as a lateral root (LR)-preferential auxin inhibitor in Arabidopsis (Arabidopsis thaliana) in a manner that is independent of the JA receptor, CORONATINE INSENSITIVE1 (COI1). Treatment of wild-type Arabidopsis with either (-)-JA or (+)-JA reduced primary root length and LR number; the reduction of LR number was also observed in coi1 mutants. Treatment of seedlings with (-)-JA or (+)-JA suppressed auxin-inducible genes related to LR formation, diminished accumulation of the auxin reporter DR5::GUS, and inhibited auxin-dependent DII-VENUS degradation. A structural mimic of (-)-JA and (+)-coronafacic acid also inhibited LR formation and stabilized DII-VENUS protein. COI1-independent activity was retained in the double mutant of transport inhibitor response1 and auxin signaling f-box protein2 (tir1 afb2) but reduced in the afb5 single mutant. These results reveal JAs and (+)-coronafacic acid to be selective counter-auxins, a finding that could lead to new approaches for studying the mechanisms of LR formation.

    英語, 研究論文(学術雑誌), Perfluoroalkyl substances (PFAS) are persistent bio-accumulative chemicals that impact the health of pregnant women and their children. PFAS derive from environmental and consumer products, which depend on human lifestyle, socioeconomic characteristics, and time variation. Here, we aimed to explore the temporal trends of PFAS in pregnant women and the characteristics related to maternal PFAS concentration. Our study is part of the Hokkaido Study on Environment and Children's Health, the Hokkaido large-scale cohort that recruited pregnant women between 2003 and 2011. Blood samples were acquired from pregnant women during the third trimester to measure PFAS and cotinine concentrations. Maternal basic information was collected with a baseline structured questionnaire. Eleven PFAS were measured from 2123 samples with ultra-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry. Eight PFAS were above 80% detection rate and were included in the final analysis. We used multivariable linear regression to analyze the association of pregnant women characteristics with the levels of eight PFAS. The temporal trend of PFAS was observed in two periods (August 2003 to January 2006 and February 2006 to July 2012). The concentration of perfluorooctane sulfonate (PFOS) significantly decreased from August 2003 to January 2006 and from February 2006 to July 2012. The concentrations of perfluorododecanoic acid (PFDoDA), perfluoroundecanoic acid (PFUnDA), and perfluorotridecanoic acid (PFTrDA) increased significantly between August 2003 and January 2006, whereas they decreased significantly between February 2006 and July 2012. Women with pre-pregnancy body mass index (BMI) >25 kg/m² had lower PFUnDA, PFDoDA, and PFTrDA levels than did those with normal BMI (18.5⁻24.9 kg/m²). Pregnant women, who were active smokers (cotinine > 11.49 ng/mL), had higher PFOS than the non-smokers (cotinine < 0.22 ng/mL). Lower levels of PFHxS, PFOS, PFOA, PFNA, and PFDA were observed in women, who had given birth to more than one child. There were also significant positive associations between PFAS levels and annual income or maternal education. PFAS levels varied in women with higher pre-pregnancy BMI, active smoking status, higher education level and annual income. The causes of the individual PFAS differences should be explored in an independent study.

    英語, 研究論文(学術雑誌), The isoleucine conjugate of 12-oxo-phytodienoic acid (OPDA-Ile), a new member of the jasmonate family, was recently identified in Arabidopsis thaliana and might be a signaling molecule in plants. However, the biosynthesis and function of OPDA-Ile remains elusive. This study reports an in vitro enzymatic method for synthesizing OPDA-Ile, which is catalyzed by reactions of lipoxygenase (LOX), allene oxide synthase (AOS), and allene oxide cyclase (AOC) using isoleucine conjugates of α -linolenic acid (LA-Ile) as the substrate. A. thaliana fed LA-Ile exhibited a marked increase in the OPDA-Ile concentration. LA-Ile was also detected in A. thaliana. Furthermore, stable isotope labelled LA-Ile was incorporated into OPDA-Ile. Thus, OPDA-Ile is biosynthesized via the cyclization of LA-Ile in A. thaliana.

    英語, 研究論文(学術雑誌), We synthesized a novel linker (1) with biotin, alkyne and amino groups for the identification of target proteins using a small molecule that contains an azide group (azide probe). The alkyne in the linker bound the azide probe via an azide-alkyne Huisgen cycloaddition. A protein cross-linker effectively bound the conjugate of the linker and an azide probe with a target protein. The covalently bound complex was detected by western blotting. Linker 1 was applied to a model system using an abscisic acid receptor, RCAR/PYR/PYL (PYL). Cross-linked complexes of linker 1, the azide probes and the target proteins were successfully visualized by western blotting. This method of target protein identification was more effective than a previously developed method that uses a second linker with biotin, alkyne, and benzophenone (linker 2) that acts to photo-crosslink target proteins. The system developed in this study is a method for identifying the target proteins of small bioactive molecules and is different from photo-affinity labelling.

    英語, 研究論文(学術雑誌), Jasmonic acid (JA) is involved in a variety of physiological responses in seed plants. However, the detection and role of JA in lycophytes, a group of seedless vascular plants, have remained elusive until recently. This study provides the first evidence of 12-oxo-phytodienoic acid (OPDA), JA and jasmonoyl-isoleucine (JA-Ile) in the model lycophyte Selaginella moellendorffii. Mechanical wounding stimulated the accumulation of OPDA, JA and JA-Ile. These data were corroborated by the detection of enzymatically active allene oxide synthase (AOS), allene oxide cyclase (AOC), 12-oxo-phytodienoic acid reductase 3 (OPR3) and JA-Ile synthase (JAR1) in S. moellendorffii. SmAOS2 is involved in the first committed step of JA biosynthesis. SmAOC1 is a crucial enzyme for generating the basic structure of jasmonates and is actively involved in the formation of OPDA. SmOPR5, a functionally active OPR3-like enzyme, is also vital for the reduction of (+)-cis-OPDA, the only isomer of the JA precursor. The conjugation of JA to Ile by SmJAR1 demonstrates that S. moellendorffii produces JA-Ile. Thus, the four active enzymes have characteristics similar to those in seed plants. Wounding and JA treatment induced the expression of SmAOC1 and SmOPR5. Furthermore, JA inhibited the growth of shoots in S. moellendorffii, which suggests that JA functions as a signaling molecule in S. moellendorffii. This study proposes that JA evolved as a plant hormone for stress adaptation, beginning with the emergence of vascular plants.

    英語, 研究論文(学術雑誌), 12-Oxo-phytodienoic acid (OPDA) is induced by mechanical wounding and suppresses the growth of Physcomitrella patens; OPDA is considered as a signal compound in this moss species. In this study, a proteomic analysis of P. patens protonemata treated with OPDA was performed. The abundance levels of 41 proteins were significantly altered by OPDA, with decreased levels for 40 proteins. The proteins for which abundance decreased in response to OPDA at the protonema developmental stage were mainly involved in the metabolism of proteins and carbohydrates. The effects of inhibition on protein abundance are likely a major physiological function of OPDA in P. patens. OPDA also suppressed the expression of histones at the protein level and gene transcription level. Suppression of histone expression might be an OPDA-specific function in P. patens protonemata. In P. patens, a subset of the physiological responses caused by OPDA is shown to differ between protonema and gametophore developmental stages.

    英語, 研究論文(学術雑誌), BACKGROUND: Color patterns in angiosperm flowers are produced by spatially and temporally restricted deposition of pigments. Identifying the mechanisms responsible for restricted pigment deposition is a topic of broad interest. Some dicots species develop bicolor petals, which are often caused by the post-transcriptional gene silencing (PTGS) of chalcone synthase (CHS) genes. An Asiatic hybrid lily (Lilium spp.) cultivar Lollypop develops bicolor tepals with pigmented tips and white bases. Here, we analyzed the global transcription of pigmented and non-pigmented tepal parts from Lollypop, to determine the main transcriptomic differences. RESULTS: De novo assembly of RNA-seq data yielded 49,239 contigs (39,426 unigenes), which included a variety of novel transcripts, such as those involved in flavonoid-glycosylation and sequestration and in regulation of anthocyanin biosynthesis. Additionally, 1258 of the unigenes exhibited significantly differential expression between the tepal parts (false discovery rates <0.05). The pigmented tepal parts accumulated more anthocyanins, and unigenes annotated as anthocyanin biosynthesis genes (e.g., CHS, dihydroflavonol 4-reductase, and anthocyanidin synthase) were expressed 7-30-fold higher than those in non-pigmented parts. These results indicate that the transcriptional regulation of biosynthesis genes is more likely involved in the development of bicolor lily tepals rather than the PTGS of CHS genes. In addition, the expression level of a unigene homologous to LhMYB12, which often regulates full-tepal anthocyanin pigmentation in lilies, was >2-fold higher in the pigmented parts. Thus, LhMYB12 should be involved in the transcriptional regulation of the biosynthesis genes in bicolor tepals. Other factors that potentially suppress or enhance the expression of anthocyanin biosynthesis genes, including a WD40 gene, were identified, and their involvement in bicolor development is discussed. CONCLUSIONS: Our results indicate that the bicolor trait of Lollypop tepals is caused by the transcriptional regulation of anthocyanin biosynthesis genes and that the transcription profile of LhMYB12 provides a clue for elucidating the mechanisms of the trait. The tepal transcriptome constructed in this study will accelerate investigations of the genetic controls of anthocyanin color patterns, including the bicolor patterns, of Lilium spp.

    英語, 研究論文(学術雑誌), Natural pyrethrins are used to control household and agricultural pests, and it is of value to understand biosynthesis in Tanacetum cinerariifolium for enhanced production. We previously found that a blend of four green leaf volatiles (GLVs) and (E)-β-farnesene emitted by T. cinerariifolium seedlings enhanced gene expressions of certain biosynthetic enzymes in unwounded seedlings; however, the extent to which such a regulation facilitates pyrethrin biosynthesis remains unknown. Here we have investigated the effects of the blend of the volatile organic compounds (VOCs) on gene expressions of seven biosynthetic enzymes. VOC treatment resulted in enhanced chrysanthemyl diphosphate synthase (CDS), chrysanthemic acid synthase (CAS), Tanacetum cinerariifolium GDSL lipase (TcGLIP) and acyl-Coenzyme A oxidase 1 (ACX1) gene expressions that reached a peak at a 12 h VOC treatment, whereas the treatment minimally influenced the expressions of other biosynthetic genes. In undifferentiated Tanacetum tissues, such VOC-induced amplification of CDS, CAS, TcGLIP and ACX1 gene expressions were markedly reduced, suggesting that a high-resolution, VOC-mediated communication is an event selective to differentiated plants.

    【目 的】

    植物は大地に根を張り移動が困難である事から、自己の被る様々な環境要因,ストレスに適応して生活環を終結させなくてはならない。よって、植物は独自の環境応答機構を有している。この応答機構を司る生理活性物質として植物ホルモンと呼称される一群の化合物が知られ、多くの研究がなされてきた。我々の研究室では長年、植物ホルモンの一種であるジャスモン酸(JA)について、鋭意研究を行っている。JA類は植物の傷害応答シグナル物質として必須であり、他の興味ある生理活性としてバレイショ塊茎の誘導活性、植物の就眠運動における就眠誘導、花粉管伸長促進などが知られている。近年、JA類の生理活性の制御の観点から、配糖化、チトクロームP450による酸化などに注目した報告がある。

    我々はJA類の配糖体化に関して研究を進め、イネに含まれるOsSGTを12-hydroxyJA(12-OHJA)配糖化酵素として報告した[1]。OsSGT は糖供与体としてUDP-Glcを用いるが、12-OHJAよりサリチル酸(SA)に対してより高い糖転位活性を示した。しかしながら、本酵素の探索過程において、SAに対してほとんど配糖化活性を示さず、12-OHJAに特異性の高いUDP-Glc非依存性の配糖化酵素の存在も明らかとした。現在のところ、UDP-Glc非依存性の植物2次代謝産物を標的とした配糖化酵素に関しては松葉らの報告[2]があるのみであり、植物ホルモンの配糖体化に関してUDP-Glc非依存性の糖転位酵素が関与しているとの報告は一切無い。

    上記の興味ある発見の詳細を明らかとすべく我々は、1)イネカルスに含まれるUDP-Glc非依存性の配糖化酵素の精製、2)イネカルスに含まれる本配糖化酵素の糖供与体の単離精製、構造決定,3)本配糖化酵素の諸性質の究明を進めたところ、本配糖化酵素はb−glucosydase, OsBGlu1 (accession number: AK100165)であると突き止め、イネにおいてサリチル酸グルコシド(SAG)が糖供与体として働くことを明らかとした(図1)。本酵素の生理学的意義は水酸化JA類を配糖化しJAの活性調節に寄与していると示唆できた事から、本成果について報告する。

    【研究方法および結果】

    1. UDP-Glc非依存性配糖化酵素の発見

    イネカルス粗酵素溶液にUDP-Glcを糖供与体としない12-OHJA 選択的な配糖化酵素が存在する事を、市販の糖供与体を用い、以下の実験より発見した。糖転位反応液としてイネカルスより抽出した粗酵素溶液、糖受容体としてJA水酸化体の一種である12-OHJA、糖供与体として市販のGlc 1-phosphate, TDP-Glc, octyl-Glc, UDP-Glcを用いて実験を行った。その結果、octyl-Glc はUDP-Glcよりも12-OHJAにより選択的に糖を供与し、SAはほとんど配糖化されなかった。

    2. イネ由来のUDP-Glc非依存性配糖化酵素の同定

    12-OHJA選択的糖転位活性を指標に、イネカルス粗酵素溶液に含まれる糖転位酵素の同定を試みた。糖供与体としてoctyl-Glc、糖受容体として12-OHJAを用い、種々の精製操作の後、得られた精製タンパク質はペプチドマスフィンガープ

    英語, 研究論文(学術雑誌), Perfluoroalkyl acids (PFAAs) are persistent organic pollutants that are detected in humans worldwide. Laboratory animal studies have shown that PFAAs are associated with immunotoxic effects. However, epidemiological studies investigating the role of PFAAs, in particular PFAAs with longer chains than perfluorooctanoic acid, are scarce. We investigated associations between prenatal exposure to PFAAs, including long-chain compounds, and infant allergic diseases at 12 and 24months in a large study population. The participants included mothers and their infants who enrolled in the Hokkaido Study on Environment and Children's Health 2003-2009. Eleven PFAAs were measured in maternal plasma taken at 28-32weeks of gestation using ultra-performance liquid chromatography coupled to triple quadrupole tandem mass spectrometry. Characteristics of participants and information on infant allergic diseases were obtained from self-administered questionnaires and medical records. At 24months, the adjusted odds ratio (OR) (first vs. fourth quartiles) for eczema in association with higher maternal perfluorotridecanoic acid (PFTrDA) levels was 0.62 (95% confidence interval (CI) 0.45, 0.86). After stratification by gender, the adjusted ORs in female infants from mothers with higher maternal perfluoroundecanoic acid (PFUnDA) and PFTrDA levels were also statistically significant (PFUnDA: OR=0.50; 95% CI, 0.30, 0.81; PFTrDA: OR=0.39; 95% CI, 0.23, 0.64). Our findings suggest that lower prenatal exposure to PFTrDA may decrease the risk of developing eczema in early childhood, only in female infants.

    英語, 研究論文(学術雑誌), Perfluoroalkyl acids (PFAAs) are persistent organic pollutants that are used in a wide range of consumer products. Recent epidemiological studies have shown that prenatal exposure to toxic levels of PFAAs in the environment may adversely affect fetal growth and humoral immune response in infants and children. Here we have characterized levels of prenatal exposure to PFAA between 2003 and 2011 in Hokkaido, Japan, by measuring PFAA concentrations in plasma samples from pregnant women. The study population comprised 150 women who enrolled in a prospective birth cohort study conducted in Hokkaido. Eleven PFAAs were measured in maternal plasma samples using simultaneous analysis by ultra-performance liquid chromatography coupled to triple quadrupole tandem mass spectrometry. At the end of the study, in 2011, age- and parity-adjusted mean concentrations of perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluoroundecanoic acid (PFUnDA), perfluorododecanoic acid (PFDoDA), perfluorotridecanoic acid (PFTrDA), perfluorohexane sulfonate (PFHxS), and perfluorooctane sulfonate (PFOS) were 1.35ng/mL, 1.26ng/mL, 0.66ng/mL, 1.29ng/mL, 0.25ng/mL, 0.33ng/mL, 0.28ng/mL, and 3.86ng/mL, respectively. Whereas PFOS and PFOA concentrations declined 8.4%/y and 3.1%/y, respectively, PFNA and PFDA levels increased 4.7%/y and 2.4%/y, respectively, between 2003 and 2011. PFUnDA, PFDoDA, and PFTrDA were detected in the vast majority of maternal samples, but no significant temporal trend was apparent. Future studies must involve a larger population of pregnant women and their children to determine the effects of prenatal exposure to PFAA on health outcomes in infants and children.

    英語, 研究論文(学術雑誌), Plants produce jasmonic acid (JA) and its amino acid conjugate, jasmonoyl-L-isoleucine (JA-Ile) as major defense signals in response to wounding and herbivory. In rice (Oryza sativa), JA and JA-Ile rapidly increased after mechanical damage, and this increase was further amplified when the wounds were treated with oral secretions from generalist herbivore larvae, lawn armyworms (Spodoptera mauritia), revealing for the first time active perception mechanisms of herbivore-associated elicitor(s) in rice. In the rice genome, two OsJAR genes can conjugate JA and Ile and form JA-Ile in vitro; however, their function in herbivory-induced accumulation of JA-Ile has not been investigated. By functional characterization of TOS17 retrotransposon-tagged Osjar1 plants and their response to simulated herbivory, we show that OsJAR1 is essential for JA-Ile production in herbivore-attacked, field-grown plants. In addition, OsJAR1 was required for normal seed development in rice under field conditions. Our results suggest that OsJAR1 possesses at least two major functions in rice defense and development that cannot be complemented by the additional OsJAR2 gene function, although this gene previously showed overlapping enzyme activity in vitro.

    日本語, Determining the mobile signal used by plants to defend against biotic and abiotic stresses has proved elusive, but jasmonic acid (JA) and its derivatives appear to be involved. Using deuterium-labeled analogs, we investigated the systemic transport of jasmonoyl isoleucine (JA-Ile) in response to leaf wounding in tobacco (Nicotiana tabacum) and tomato (Solanum lycopersicum) plants. It was found that de novo synthesized JA-Ile responded to wound damages was transported to induce JA-mediated wound response in healthy systemic organ.

    英語, 研究論文(学術雑誌), The endogenous concentration of N-jasmonoyl-L-isoleucine (JA-Ile) is regulated by the balance between biosynthesis and deactivation and controls plant developmental processes and stress responses. Therefore, profiling of its precursors and metabolites is required to understand the mechanism by which the JA-Ile concentration is regulated. Also, other hormones, such as indole-3-acetic acid, abscisic acid, salicylic acid, and ethylene, have been suggested to interact with JA-Ile signaling. Profiling of these hormones and their metabolites should give us insights into their interaction mode. Liquid chromatography-electrospray ionization-tandem mass spectrometry has enabled us to develop a highly sensitive and high-throughput comprehensive quantification analysis of phytohormones.

    日本語, The hormonal action of jasmonate in plants is controlled by the precise balance between its biosynthesis and catabolism. It has been shown that jasmonyl-L-isoleucine (JA-Ile, 6) is the bioactive form involved in the jasmonate-mediated signaling pathway. However, the catabolism of JA-Ile (6) is poorly understood. Although a metabolite, TA-Ile (7), has been characterized, detailed functional studies of the compound and the enzyme that produces it have not been conducted. In our results, the kinetics of wound-induced accumulation of TA-Ile (7) in plants was examined, and its involvement in plant wound response is described. Candidate genes for the catabolic enzyme were narrowed down from 272 Arabidopsis cytochrome P450 genes using Arabidopsis mutants. The candidate gene was functionally expressed in Pichia pastoris to reveal that CYP94B3 encodes JA-Ile (6) 12-hydroxylase. Expression analyses demonstrate that expression of CYP94B3 is induced by wounding and shows the activity toward JA-Ile (6). Plants grown in medium containing JA-Ile (6) show higher sensitivity to JA-Ile (6) in cyp94b3 mutants than in wild-type plants. These results demonstrate that CYP94B3 plays a major regulatory role in controlling the level of JA-Ile (6) in plants. CYP94B3 can use other JA-amino acid conjugates as substrates. Our other results uncovered that JA amino acid conjugates induced by wounding, JA-Phe and JA-Val, possessed biological activities same as JA-Ile (6).

    日本語, Tuber development of potato plants (Solanum tuberosum L.) was controlled by environmental factors, mainly by photoperiods. Short days stimulate this process, but long days have opposite effect against this process. This means potato plants distinguish the day length. But it is still unknown the relationships between day length and potato tuber inducing compounds, jasmonic acid (JA), 12-hydroxyjasmonic acid (tuberonic acid, TA), and tuberonic acid glucoside (TAG), since there is no qualitative and quantitative analysis method for these compounds. The synthesis of deuterium labeled TAG, TA, JA, (1R, 2R) 3-ox-2-(2'-pentenyl)-cyclopentanebutanoic acid (OPC 4: 0), (1R 2R) 3-oxo-2-(2'-pentenyl)-cyclopentanehexanoic acid (OPC 6: 0), and (1R, 2R) 3-oxo-2-(2'-pentenyl)-cyclopentaneoctanoic acid (OPC 8: 0) were accomplished. The qualitative and quantitative analysis for the endogenous jasmonides was carried out using these compounds as internal standards and monitoring by liquid chromatography/mass spectrometry (LC-SIM). This methodology was applied to estimate the endogenous jasmonides, TAG, TA, JA, OPC 4: 0, OPC 6: 0, and OPC 8: 0, in potato plant. The contents of TAG, TA, JA in the leaflets of potato (Solanum tuberosum L. cv. Irish Cobbler) which were harvested in July, Hokkaido, were estimated to be 7-5μg/1g leaflets, 170-100 ng/1g leaflets and 20-10ng/1g leaflets, respectively, and those of OPC 4: 0, OPC 6: 0, OPC 8: 0 to be below ng level/1g leaflets. The contents of TAG of the leaflets of potato which grown under long and short day conditions were analyzed, respectively, by means of this developed methodology. The contents of TAG were higher in the leaflets grown under long days than in those grown in short days. It is suggested that the short day condition might stimulate the transportation of jasmonids from leaflets to the other parts. The bio-synthetic pathway for TA and TAG was established in the first time because the deuterium leveled JA and OP 8: 0 were converted to TAG in the cultures on single-node segments of potato stem in vitro.

    日本語, Tuber forming substances from plants and microorgansms were surveyed using a bioassay consisting single-node stem segment culture. From leaves of Jerusalem artichoke (Helianthus tuberosus. L), two cyclopentanoid fatty acids, jasmonic acid(2) and methyl tuberonic acid glucoside(3), and six polyacetylene compounds(4-9) were isolated and the chemical structures were determinded. From the fungi, Lasiodiplodia theobromae IFO 31059, a cyclohexene epoxide(10) and mellein(11) were isolated. Cyclopentanoid fatty acids(2,3) have revealed tuber forming activity at more than 10^<-5>M and cyclohexene epoxide(10) at 10^<-4>M. Polyacetylene compounds(4-9) and mellein(11) have displayed weak activity.

    日本語, The concept of tuber forming stimulus of potato has been suggested by grafting experiments. Recently the occurrence of the substances has been evidenced by our experiment using a bioassay of a potato single-node stem segment culture. The object of this study was to isolate and determine the chemical structure of the substance from potato leaves by using of above-mentioned bioassay. The ethanol extracts of potato leaves (100kg) was separated by means of the subsequent liquid chromatographies and HPLCs. Purification processes resulted in 2.7mg of the active compound (1) which was able to induce tuberization in vitro even in lower concentration of 0.01 ppm. The FD mass spectrum showed the molecular ion peak at m/z 388 and that of the acetate at m/z 556. These data with that of GLC suggested that the active compound (1) is a monoglucoside. The PMR spectrum (δ 4.26, d, J=8.0Hz) and CMR spectrum (δ 104.4) suggested the presence of β-D-glucose moiety. EI-HR MS of the acetate (2) showed the molecular formula, C_<26>H_<36>O_<13>. The ^1H-NMR COSY experiment revealed the partial structures, I and II. These data suggested that the active compound (1) was similar to jasmonic acid (3). The chemical structure of the active compound (1) was determined to be 3-oxo-2- (5-β-D-glucopyranosyloxy-2-cis-pentenyl)-cyclopentane-1-acetic acid. A (cis)-double bond and a carboxyl group were essential for the activity. The active compound (1) and/or similar compound(s)(jasmonic acid?) were presented in all kinds of plants.

    植物の生活史には一年生、二年生、冬型一年生、多年生などがある。冬型一年生および二年生植物は、本来、夏に発芽し越冬した翌年に急激な花茎伸長(抽台)を伴う開花、種子形成を行う。よって、子孫を残す上で夏から秋の栄養成長期間中の抽台はご法度である。しかし、上記の植物が生活環を完結させるために必須な『抽台抑制』に関しては、その抑制機構の詳細が明らかでない。よって、低分子量の生理活性物質の関与を想定し研究を進めている。本研究での実施の項目は【A】ABCの葉部から茎頂部への移動、【B】植物に存在するABC関連物質の探索、【C】ABCを受容するタンパク質とその機能、【D】シロイヌナズナ抽台誘導に関与する、ABC分解酵素をコードする遺伝子の探索、【E】早抽性および晩抽性ビートにおける遺伝子特性、【F】実農業で利用可能な、栄養成長期の抽台を抑制する植物化学調節剤の開発である。項目Aについては候補の化合物の合成に成功し、ラベルパターンの異なる化合物の合成に必要な合成方法を考案しているところである。項目Bについては、関連の化合物の単離精製、構造決定に成功し、英字の論文とした。項目Cについては、候補タンパクを釣り上げるための化合物の合成を進めている。項目D、Eについてはシロイヌナズナから選られたRNAseqデータをビートに当てはめ、相応の遺伝子を見つけつつある。項目Fについて昨年とほぼ同様な圃場実験を進めているが改良法が望まれるデータであった。

    シロイヌナズナ、ナス、トマト、トウモロコシおよびダイズを80%メタノールで抽出し、固相抽出カラムで前処理し夾雑物を除去した。本前処理で得られたサンプルをUPLC-MS/MSで分析し、代表的な脂肪酸-アミノ酸縮合体であるN-リノレノイルグルタミンが植物内に存在するのか否かを検討した。その結果、分析したいずれの植物にもN-リノレノイルグルタミンが存在することが判明した。N-リノレノイルグルタミンは、幼虫の唾液中だけではなく植物にも普遍的に存在することが示唆された。しかし、その内生量は植物により大きく異なっていた。
    GH3タンパク質ファミリーの中には、カルボキシル基を持つ植物ホルモンの3-インドール酢酸、ジャスモン酸およびサリチル酸とアミノ酸を縮合するタンパク質が存在する。グルタミンと3-インドール酪酸を縮合することが報告されているシロイヌナズナのGH3.15タンパク質の組換えタンパク質を大腸菌で生産した。本タンパク質のα-リノレン酸とグルタミンの縮合活性を評価した。その結果、GH3.15タンパク質はα-リノレン酸とグルタミンの縮合活性を示した。この結果は、植物にN-リノレノイルグルタミンが存在することを支持する結果であった。さらに、α-リノレン酸を一方の基質とし、GH3.15タンパク質に対する20種のアミノ酸の基質特異性を調べた。その結果、20種すべてのアミノ酸が本反応の基質となりうることが明らかとなった。それらの中でグルタミンは4番目に高い基質特異性を示すアミノ酸であった。
    N-リノレノイルグルタミンのシロイヌナズナの生育に対する影響を調べたところ、本化合物は100μMの濃度でシロイヌナズナの根の伸長を抑制するとともに、根を垂直ではなく、斜めに伸長させることが明らかとなった。

    植物の成長に有益な効果をもたらし、植物と共生関係にある内生菌(エンドファイト、endophyte)の存在が明らかとされ、様々な研究がなされてきた。その一例として、共生菌の一種、Veronaeopsis simplexと共生関係を結んだトマトは、本来トマト幼苗が生育できない低pH条件でも通常の生育を示す。本菌は培地上で暗色(Dark)のコロニーを形成し比較的生育が遅く、菌糸に隔壁(Septa)があることから、Dark Septate Endophytic fungus (DSE)に属する菌として知られており、根部に感染し植物に対して有益な効果を示す。他のDSE菌、 Heteroconium chaetosnira, Phialocephala fortiniiの存在も知られ、その効果が実証されている。しかしながら、『どうしてエンドファイトは植物に排除されずに感染できるか?』、『共生したエンドファイトは植物に如何にして劣悪環境突破力をあたえるのか?』については未だ不明なところが多い。本研究ではP. fortiniiの培養濾液より新規な化合物、8-hydroxy-6-methoxy-3,7-dimethyl-1H-2-benzopyrpyran-1-oneを単離し、植物に対する活性として内生のABA含量を増加させる生物活性を見出した。また、我々が主題として取り組む糸状菌由来の生理活性物質、セオブロキシドに、内生菌の感染量を増加させる活性を見出した。感染量を増加させる生理活性の発現には、内生のABA含量増加に伴う、PR1遺伝子の転写量の低下が起因しているであろうとの結果を得た。また、植物と内生菌が共生関係を結ぶ際に重要な役割が想定されているジャスモン酸の類縁体の生合成に関して、新たな知見を得た。

    地球上の埋蔵エネルギーには限りがあり、未利用バイオマス資源の有効活用は人類永続の一助となる。本資源の有効活用の観点から、これらを原料とした多く農業資材が市販され、利用されている。しかし、学術的な裏付けが乏しく、その使用が一部に限られている。大量に産出される未利用バイオマスの一事例として、ビール、日本酒、ブドウ酒、焼酎などの醸造過程の副産物があげられる。本課題ではワイン酒醸造後の残渣種子を中心に研究を行い、バレイショ増収効果に期待がもたれる資材であるとこを報告する。本研究の成果は資源循環型の社会構築に向けた研究事例のモデルケースとなる。

    植物の生態型には一年生、冬一年生および多年生などがある。冬一年生植物は夏に発芽し、越冬後の春に抽だい、花成誘導を行う。よって、夏から秋の栄養成長期間中の抽だいは厳密に抑制されなければならない。植物の抽だい抑制機構に関しては低分子生理活性物質の関与が示唆されているが、長距離シグナルとしての実態や移動先での作用メカニズムは不明な点が多い。本研究では葉部で生合成された生理活性物質の茎頂点への移動と移動先での生理活性を明らかとし、環境条件によって制御される植物の抽だい抑制機構を明らかとすることを目的とした。
    ダイコン葉部より、2,3-dihydroxypropyl (7Z,10Z,13Z)-hexadeca-7,10,13-trienoateが抑制物質として単離されている。活性に必要な官能基を探るために構造活性相関研究を行なった。材料にはシロイヌナズナを用い、播種後の植物の伸長抑制効果を指標とした。この結果、母骨格に結合する炭素鎖に関して、1箇所でも二重結合があれば活性を有し、cis,trans体のいずれでも活性を有することが明らかとなった。他器官への移動を検証するための重水素ラベル体についてはラベルパターン異なる化合物を合成できた。
    また、ジベレリンに対する生合成抑制効果についてはその内生量をUPLC MS/MSによって測定した。この結果、抽台抑制物質に晒されたシロイヌナズナでは全体的なジベレリン含量が下がっていることが明らかとなった。本結果は抽台抑制化合物のターゲットはジベレリン生合成の初期段階を抑制していることが示唆された。さらにプランターで育てた大根(品種:耐病そう太り)に2,3-dihydroxypropyl (7Z,10Z,13Z)-hexadeca-7,10,13-trienoateを一定期間葉面散布したところ、無処理の植物に比べて、抽台時期の遅延効果が示された。

    本研究は、動物や陸上植物とは異なる進化の過程で,独自に多細胞体制を獲得した褐藻類の傷害応答機構に注目し,傷害応答における植物ホルモンの役割を明ら かにすることを目標として掲げている。具体的には、褐藻アミジグサで既にオーキシンによる促進作用が確認されている傷害組織の癒合に焦点を当て、オーキシ ンの合成から組織内の移動、作用機序までの各段階を形態学的・分子生物学的アプローチを用いて解明する予定である。
    本年度は3つのサブプロジェクトを進めた。一つ目は傷害の形状や位置における生長促進作用と側芽形成数の比較から、傷害シグナルが作用する組織と傷害との位置関係を考察した。傷害の形状は2型を比較したところ、その生長促進作用に違いが見られた。さらに傷害応答の際には、生長促進作用と側芽形成との間にトレードオフの関係が生じることが明らかとなった。この結果は日本藻類学会第42回大会(東北大学)にて発表された。二つ目は傷害応答におけるトランスクリプトームの再解析を行い、傷害で活性化する遺伝子は抑制される遺伝子の10分の1であることが判明した。さらに遺伝子オントロジー解析から特に傷害によって発現が促進される遺伝子群についての機能同定を試みた。三つ目として、オーキシンを含む植物ホルモンが潜在的に褐藻類、特に本研究の研究対象であるアミジグサ類に含まれるか否かについて検証した。アミジグサ類は沖縄を中心に亜熱帯地域に多くの種類が生息するため、26個体の天然アミジグサ類藻体についてUPLC-MS/MSを用いた解析を行った。その結果、特定の植物ホルモンについてその存在が示された。さらに分子系統解析を用いて正確なアミジグサ類の種同定を行ったところ、日本新産種と思われる数種を発見した。現在はこれらの知見を投稿論文としてまとめている。

    モデル実験により、生理活性物質にアジド基を有するプローブ(アジドプローブ)と、アミノ基、アルキンおよびビオチンを有するリンカーを用いて標的タンパクを同定する方法が有効であることが示された。そこで本手法を用いて、植物生長促進活性を有するアザヒポキサンチン(AHX)の結合タンパク質の同定を試みた。
    モデル植物であるイネのタンパク質抽出液にアジド基を導入したAHX(N3-AHX)を添加し、タンパク質とN3-AHXを十分に相互作用させた。タンパク質とN3-AHXの複合体は、リンカーを介してストレプトアビジン固定化レジンに結合させた。非特異的にレジンに結合するタンパク質を十分に洗浄した後に、N3-AHXと結合するタンパク質を選択的に溶出させた画分(Fr.1)が得られた。イネのタンパク質抽出液に過剰のAHXを添加し、Fr.1を得た方法と同様な方法で得られた画分をFr.2とした。イネのタンパク質抽出液を何も結合させていないストレプトアビジン固定化レジンに供した後、本レジンに非特異的に結合するタンパク質が溶出がされた画分をFr.3とした。この3つの画分をそれぞれnano-LC-MS/MSに供し、各画分に含まれるタンパク質を検出した。Fr.1にのみ含まれ、Fr.2およびFr.3には含まれないタンパク質が14個あり、これらのタンパク質がAHXに結合する候補タンパク質と推定された。その中で、Os07t0112800(Similar to Eukaryotic translation initiation factor 5A-4 (eIF-5A-4))が、ウェスタンブロッッティングによりAHXとの結合が確認された。本タンパク質はAHX結合タンパク質として有望であることが示された。

    植物の傷害応答機構、特にジャスモン酸(JA)シグナル伝達機構の不活性化に寄与すると想定される配糖化酵素として、OsBGlu1を同定した。種々のJA類を用いてイネ幼苗の根の伸長阻害試験を行った。この結果、JAが最も伸長阻害を示し、12-hydroxyjasmonic acid および12-hydrohyjasmonoyl L-isoleucine配糖体がほとんど伸長阻害を示さなかった。以上の事から生理活性を示すJAの重要な代謝経路の一つとして、OsBGlu1が介する糖転位反応を証明できたと考える。

  • スイカ果実に含まれるスイカ種子発芽抑制物質の有機化学的研究
    科学研究費助成事業 基盤研究(C)
    2009年 - 2011年
    松浦 英幸
    植物は大地に根を張って生きねばならない故、環境要因が悪化したからといって逃げ出す事はできない。よって、植物は生育環境に応じて発芽、生育,開花、結実の行程を踏み、環境要因に呼応して次の生育ステージへ移行する。植物の生活環制御は興味に尽きない。ここで、植物に含まれる低分子生理活性物質に目を向けた場合、植物ホルモンと呼ばれる一群の生理活性物質が知られている。種子発芽の抑制もしくは促進、栄養生長時に於ける大盛な生長、栄養生長にブレーキを踏み生殖生長(老化)に切り替える働き等、植物ホルモンが関与している事例が多く知られ、鋭意研究が行われている。しかしながら多くの研究者が植物の生活環制御の不思議さ,巧妙さに興味を抱きつつ、研究がなされてきたが、「種子の発芽は果実中に存在する限り起こりえない」と云う事例に目を向けた研究は未だに行われていない。この事象についてスイカ果実を実験材料として用い、植物ホルモンの一種であるアブシシン酸が主たる活性物質である事を明らかとした。本年度は他の植物を用いて上記の生物現象を検討した。数種の植物を用いて検証したところ、果実と種子が直接接しているような植物においては化学物質を介した果実中での発芽抑制機構が存在する事が示唆された。そこで、発芽抑制の確認されたトマト(Solanum lycopericum)を用いて、果実中の発芽抑制物質の単離を試みた。今の所、単離、精製を試みている段階であり、生理活性物質の実態は不明である。しかしながら、精製を進めた段階に於いてもトマト種子発芽抑制活性を有する事から数ステップの精製操作により目的化合物の取得が可能と思われる。

    ヒメツリガネゴケ(Physcomitrella patens)におけるオクタデカノイド経路中(ジャスモン酸生合成)の各種酵素の活性を調べた。その結果、いずれの酵素も高等植物と同様の酵素活性が示された。ヒメツリガネゴケの生育においては、ジャスモン酸(JA)がほとんど影響を与えなかったのに対して、その生合成中間体である12-オキソファイトジエン酸(OPDA)は生育を阻害した。オクタデカノイド経路に関わる酵素遺伝子の変異株を作製したが、それらの表現型は野生株と大きな差異は無かった。本研究の結果から、ヒメツリガネゴケではJA ではなくOPDA が活性化合物として機能していることが示唆された。

    インドネシア・カリマンタンの負荷土壌に対処できる根圏微生物コンソーシアムについて検討した。中強酸性泥炭湿地に自生するチガヤ根面から分離したBurkholderia属細菌A-KA株にSphingomonas属など根圏微生物の増殖を促進する活性が認められ,また,酸性硫酸塩土壌耐性イネ根から分離したBurkholderia mimosarumにはイネ苗立枯細菌病を引き起こすBurkholderia plantarii々のトロポロン産生を抑え,種子付着菌を根圏で増殖させる能力を示した。熱帯のポリフェノールリッチな土壌とフタバガキ幼木根圏から分離した細菌群からは,ピロガロール基をもつポリフェノール存在でインドール分解活性が急激に活性化されるBurkholderia属細菌を見いだした。共生系では,ソテツ根と窒素固定性シアノバクテリアNostoc punchiformeとのサンゴ状根共生において,シアノバクテリア誘引に必要な運動性付与がジアシルグリセロールの一分子種で起こることを明らかにした。また,宿主の土壌伝播病原菌感染を抑制する根圏細菌Psuedomonas jessenii EC-S101株やTrichoderma sp. PS1-7株の放出するシグナル物質の化学構造とその機能性を解明した。根圏での脱窒制御に関しては,熱帯泥炭地の亜酸化窒素生成菌では亜酸化窒素還元酵素(N2OR)遺伝子が欠損しており,また,様々な植物二次代謝産物が根圏での脱窒能に影響を与えることが明らかにされた。

  • 糸状菌由来生理活性物質によるバレショマイクロチューバー技術の弱点の補完とその応用
    2008年 - 2008年
    松浦 英幸
    バレイショの分裂組織を無菌的に増殖し、マイクロチューバーを作成、これを種芋として用いる技術が注目されている。収穫時期に制限が無い点、病原菌およびウィルスフリーの植物体が大量に得られる点、従来の種芋より小径で輸送コスト、播種時のエネルギーコストが低く、これらの点で大変有望な技術である。しかしながら、初期生育段階での乾燥、低温耐性の点で問題点を抱えている。本課題ではマイクロチューバー誘導期に糸状菌由来の生理活性物質を施し上記問題点の克服を目指す。

    インドネシア熱帯泥炭林荒廃地の滅菌現地土壤(ペースト状の木質泥炭)におけるX.comp1anataの種子発芽はPenicillium属糸状菌Y-1株によってのみ強力に促進されたが、発芽種子は子葉の伸長以降は成長できず、1ヶ月後には真菌がまとわりついた様に立ち枯れて死に絶えてしまった。とこ芽種子は極めて良好な生育を6ヶ月以上持続したため、土壌生/種子付着性真菌のX.comp1anata発芽ステージでの発芽亢進機能とそれに引き続く土壌細菌のX.comp1anata芽生え生育ほう助機能とが明確に分担されていることが強く示唆された。
    シベリア永久凍土のタイガ林林床土壌では、低栄養要求性の単生窒素固定性Burkholderia属ならびにPseudomonas属細菌が主要な菌相をなし、細菌群集は0.02〜O.05%のマンニトールで十分に1%炭素源以上のアセチレン還元活性を示すことが分かった。また、表層に近い腐植成分を多く含む層から得た土壌微生物群集の窒素固定能力は10〜15℃で最大限に発揮されること、中一アルカリ性(pH 6.0以上)では極端に抑えられ、弱酸性(pH 5.0付近)では極めて高い能力が発揮されることから、現地負荷環境条件の再現が当該微生物コンソーシアムの機能性を最大限に発揮させると結論付けた。
    2000年に噴火した有珠山の火山性荒廃地における先駆性植物の外生菌根(ECM)およびアーバスキュラー菌根(AM)共生について調査した。荒廃地に優占的に更新するヤナギ類3種、ドロノキ(Populusmaximowiczii)、エゾノバッコヤナギ(Salix hultenii var. angustifolia)およびオノエヤナギ(Salix sachalinensis)は定常的にECMを形成しており、全体での外生菌根形成率は、17〜42%であった。草本ではスギナとオオイタドリ以外の10種は全てAMを形成していた。植生再生の初期過程においては、菌根共生が植生再生と根圏土壌環境負荷緩和に先駆的役割を果たしていることが示された。

    Theobroxide(1mM水溶液、1粒/40ml)をカウピー(Vigna unguiculata)播種時の苗床に施し、播種約10日後、傷害応答シグナルとして認知されているsalicyhc acid(SA),salicylic acid glucoside(SAG)の幼植物内での含有量を測定した。Theobroxide処理の植物においてこれらの化合物の有意な蓄積量の上昇が確認された。傷害耐性付与が期待できたので、断水処理、キュウリモザイクウィルスの接種ならびにダイズ茎疫病菌の接種、それぞれ3つの処理を行った。これらの3種のストレスに対してtheobroxide処理の植物は無処理の植物と比較し、有意に耐性効果が観察された。以上の結果からtheobroxideの病傷害耐性付与効果を有する農業資材としての可能性が示唆された。また、ATP生産に関わる遺伝子のうち、ATP消費を促進する遺伝子(AOX)について検討したところ、theobroxide処理の植物ではコントロールに比べ有意に抑制されていることが解り、エネルギー節約型の植物、倹約型を導いているのではないかと示唆された。また、アサガオやホウレンソウを用いてtheobroxide効果を検討したところ植物ホルモンとして知られているジベレリンに対して何らかの阻害作用を示しているデータが得られた。

    1.セオブロキシド処理による花芽形成誘導
    すでに効果が明らかになっているアサガオ以外の植物の花芽形成誘導について調べた。1mMセオブロキシド水溶液を2日に1回植物葉に散布した。その結果、短日性植物であるイネ、イチゴ、ダイズ、ポインセチアの花芽形成誘導に効果があった。しかし、イチゴ、ダイズでは品種間の差異が大きかった。
    2.セオブロキシドの処理による塊茎形成誘導
    実験室レベルでバレイショにセオブロキシド水溶液を散布することにより塊茎形成が誘導されるが、圃場実験でも20%の収量の増大が認められた。さらに、バレイショの病害抵抗性の付与にも関与することが明らかになり、病害防除とともに植物化学調節剤としての実用化の可能性が大きくなった。
    3.セオブロキシド処理による抽苔抑制
    長日条件で抽苔するホウレンソウにセオブロキシド水溶液を散布したところ、長日で抽苔を抑制する効果が認められた。植物化学調節剤としての実用化とともに抽苔現象解明のプローブとして重要な役割を持つ化合物であることが明らかとなった。
    4.セオブロキシドの作用機作
    リポキシゲナーゼ阻害剤サリシルヒドロキサミン酸を用いた実験により、セオブロキシドの作用機作はリポキシゲナーゼ活性を高めることが明らかになった。このことによりセオブロキシドによる塊茎と花芽形成は、リノレン酸酸化物の生成が促進され、その酸化物により両者の誘導が行われるとの結論に達した。
    5.セオブロキシド製造特許
    醗酵法および合成法によるセオブロキシドの製造法を開発し、特許を申請した。
