Scientific journal, Abstract
Squalene is a triterpenoid compound and widely used in various industries such as medicine and cosmetics due to its strong antioxidant and anticancer properties. The purpose of this study is to increase the accumulation of squalene in filamentous fungi using exogeneous butenafine hydrochloride, which is an inhibitor for squalene epoxidase. The detailed settings achieved that the filamentous fungi, Trichoderma virens PS1-7, produced squalene up to 429.93 ± 51.60 mg/L after culturing for 7 days in the medium consisted of potato infusion with glucose at pH 4.0, in the presence of 200 μM butenafine. On the other hand, no squalene accumulation was observed without butenafine. This result indicated that squalene was biosynthesized in the filamentous fungi PS1-7 which can be used as a novel source of squalene. In addition, we successfully obtained highly 13C-enriched squalene by using [U-13C6]-glucose as a carbon source replacing normal glucose. - Influence of acute beetroot juice supplementation on cold-induced vasodilation and fingertip rewarming

English, Scientific journal, The tropical plant <i>Ficus microcarpa</i> L. f. cv. Golden Leaves (GL) is a high-light sensitive tropical fig tree in which sun-leaves are yellow and shade-leaves are green. We compared the response of photosynthetic activities to strong light between GL and its wild-type (WT, <i>Ficus microcarpa</i> L. f.). Field measurements of maximum photosystem II (PSII) efficiency (Fv/Fm) of intact sun-leaves in GL showed that photo synthetic activity was severely photoinhibited during the daytime (Fv/Fm = 0.46) and subsequently recovered in the evening (Fv/Fm = 0.76). In contrast, WT did not show any substantial changes of Fv/Fm values throughout the day (between 0.82 and 0.78). Light dependency of the CO<sub>2</sub> assimilation rate in detached shade-leaves of GL showed a response similar to that in WT, suggesting no substantial difference in photosynthetic performance between them. Several indicators of photoinhibition, including declines in PSII reaction center protein (D1) content, Fv/Fm value, and O<sub>2</sub> evolution and CO<sub>2</sub> assimilation rates, all indicated that GL is much more susceptible to photoinhibition than WT.

Japanese, Scientific journal, Two flavonol gylcosides were isolated from the fresh leaves of the tropical tree <i>Schefflera arboricola</i> Hayata. The major flavonol glycosides of <i>S. arboricola</i> were identified to be quercetin and kaempferol glycosides on the basis of thin layer chromatogram and absorption spectral data. The absorption coefficients of these glycosides were estimated to be 14.7 mM<sup>-1</sup>cm<sup>-1</sup> at A<sub>358</sub> (the quercetin glycoside) and 16.0 mM<sup>-1</sup>cm<sup>-1</sup> at A<sub>346</sub> (the kaempferol glycoside).

Summary national conference - Phytochemical Antioxidants: Past, Present and Future
Yasuko Sakihama; Hideo Yamasaki, Antioxidants [Working Title], 13 Jan. 2021, [Peer-reviewed], [Lead author]
Most diseases that are difficult to prevent and cure are “syndromes” that are governed by multiple components with complicated interactions. Whatever the cause of such diseases, overproduction of harmful reactive oxygen species (ROS) can often be observed in progression of the disease. Under such conditions, the cells may be challenged by “oxidative stress” due to excessively generated oxidants. Antioxidants can be defined as chemical compounds that scavenge ROS or free radicals over-produced in the cells under oxidative stress conditions. The plant pigments flavonoids and betalains, rich in fruits and vegetables, are reactive not only with ROS but also with reactive nitrogen species (RNS) and possibly with reactive sulfur species (RSS). Here, we provide an overview of updates on the antioxidative functions of the plant pigments along with some prospects for future research on phytochemical antioxidants., IntechOpen, Introduction other - Betanin, a plant pigment from red beetroot, protects from peroxynitrite-induced oxidative and/or nitrosative stress in mammalian cells

Japanese - 38. Search for signal substances that are associated with coralloid root formation as an event in cycad-cyanobacteria symbiosis
Tanaka Manato; Sakihama Yasuko; Hashidoko Yasuyuki, The Janapese Society for Chemical Regulation of Plants, Abstract, 45, 0, 55, 55, 2010
Background) Nostoc sp., a cyanobacterium establishes symbiosis with cycad (Cycus revolute) root. Nostoc sp. firstly recognizes the host plant root, next moves to the root tip, and eventually induces the coralloid root. Generally Nostoc sp. does not possess motility, but it differentiates to hormogonia, a motile form. Hypothetically, cycad root releases hormogonia-inducing factor (HIF) to establish the symbiosis between them. In this research, we screened HIF-like principle from the coralloid roots. Materials and Method) The coralloid roots collected at Yaku Island in late March, 2009 (1.08kg), and at Tanegashima Island, in early May, 2010 (6.25kg), were soaked in MeOH. It was concentrated and re-suspended in water (ca. 1000ml) to be extracted with equal volume of EtOAc to give 2.58g of EtOAc solubles. In a paper disc assay, aggregated colonies of Nostoc sp. was impregnated in 0.6% Winogradsky's agar medium, and the fraction-charged paper disc (9mm diameter, 0.25mm thick) were put onto the agar plates and incubated at 25oC. When the aggregated colonies of Nostoc sp. around the paper disc started to be dispersed within 2 days, the fraction was judged to contain HIF. The active fraction was further purified to elucidate structures of HIF. Results and Discussions) After 12-h of incubation, Nostoc sp. around 40% EtOAc fraction started to be dispersed. Under a light microscopic observation, some chain-like cells turned into hormogonia, to acquire motilitiy. Using this bioassay system, pure active principle was obtained 1mg of the colorless syrup from the 1kg fr. wt. of coralloid. In spectroscopic analyses and chemical derivatization using FD-MS, ^1H-NMR and treatment with lipase followed by released fatty acid analyses by FD-MS, it was concluded that the HIF is a 1,2-diacylglycerol possessing linolic acid and palmitic acid as constitutive fatty acids., The Janapese Society for Chemical Regulation of Plants, Japanese - Dimethyl sulfoxide添加による赤カビ病菌(Fusarium sp.)のzearalenoneとaurofusarin生合成におけるトレードオフ

Japanese - Study on antioxidant functions of betalain pigments isolated from red beet
Maeda Makiko; Sakihama Yasuko; Fukushi Yukiharu; Hashidoko Yasuyuki, Plant and Cell Physiology Supplement, 2009, 0, 884, 884, 2009
Betalains are plant pigments, consisting of red betacyanins and yellow betaxanthins. Distribution of betalains is limited in Caryophyllales except for Caryophyllaceae and Molluginaceae, and betalains and anthocyanins are mutually exclusive. It has been reported that flavonoids including anthocyanins have antioxidant functions in plant. However, the physiological role of betalains in plant is not clear. Here we examined betalains as antioxidant agents to elucidate their functionality.<br> Two major betalains, beet betaxanthin(BBx) and beet betacyanin(BBc), were isolated from red beet(<I>Beta vulgaris</I> L.). Both BBx and BBc were rapidly bleached by the addition of peroxynitrite(ONOO<SUP>-</SUP>). This bleaching reaction was dependent on concentration of ONOO<SUP>-</SUP>, while suppressed by glutathione, a well-known ONOO<SUP>-</SUP> scavenger. These results indicated that betalains have an ability to quench ONOO<SUP>-</SUP>. In this present study, we also discuss antioxidant activity of betalains against reactive oxygen species., The Japanese Society of Plant Physiologists - アブラナ科植物根部より分離したバクテリアによるFusarium菌糸の伸長阻害

我々は世界で初めてメガロ糖(MS)の生産に成功した。性質を調べると、BCS IIに属す化合物(難水溶性・高膜透過性の薬剤や食品素材など)を可溶化する画期的な機能が発見された。またMSは「BCS II化合物を溶質とする糖質水溶化剤」と捉えることもできた。一方、難溶性ベンジル系アゾ色素もBCS IIに属し、かつ「東南アジア諸国における代表的な環境汚染物質」である点に注目し、MSとアゾ分解酵素を組合せることで、実験室レベルではあるが、色素の可溶化と酵素分解に成功した。以上は初めて生産したMS、すなわち従来型MSの知見である。極最近に従来型MSより高機能な新奇MS(新型MS)を発見した。本申請では、新型MSによるアゾ色素の酵素分解を目的とし、現地試験をタイで実施する。最終的な到達目標はアゾ色素の汚染解消(すなわち環境問題克服への貢献)である。
本年度もタイにおける新型コロナウイルス感染症の流行から渡航が困難となり、現地調査の断念を強いられた。タイでの調査が遅れているが、それを補うべき対策を立てて研究を進行させた。以下に本年度の成果を述べる。1)昨年までに我々が明らかにした有望な植物MS(日タイ共通植物由来のMS)に関し、タイ植物の存在確認を相手国研究協力者が行った。2)本MSの存在下でアゾ色素の酵素分解が進行した。3)自然界においてアゾ色素は土壌(色素汚染土壌)の中に存在するため、アゾ色素と土壌を混合させ「色素汚染土壌」のモデル化を図った。4)構築したモデル汚染土壌を滅菌後に、MS可溶化と酵素処理を実施し、アゾ色素分解の確認を行っている。分解量の向上を目指したい。

We investigated rhizo-biosystems that enable to mitigate adverse soils in Kalimantan, Indonesia. Burkholderia sp. strain A-KA that had been isolated from the rhizosphere of Imperata cylindrica grown in medium-strongly acidic peatland showed a growth-helper activity toward other rhizosphere bacteria, such as Sphingomonas sp. Burkholderia mimosarum isolated from rhizosphere of paddy rice tolerant to acid-sulfate soil suppressed tropolone production of B. plantarii, a bacterium causative of rice blight disease, while promoted growth of diverse root-and seed-epiphytic bacteria. Among rhizobacteria that had isolated from dipterocarpous sapling adapting to polyphenol-rich tropical peat soil, pyrogallol-containing plant polyphenols activated Burkholderia unamae CK-43B to degrade indole and some other N-heterocyclic aromatic compounds. In the coralloid root symbiotic systems between Cycas revoluta root and a nitrogen-fixing cyanobacterium Nostoc punchiforme, a diacylglycerol was found to be the principle of hormogoniu-inducing factor on the cyanobacterium necessary to its host-recognition. Also, we successfully isolated and characterized signal compounds from a rhizobacterium Pseudomonas jessenii strain EC-S101 isolated from spinach root and from a rhizosphere fungus Trichoderma virens strain PS1-7 isolated from paddy root. In the rhizosphere, nitrous oxide emitting bacteria in tropical peat soil were missing their nitrous oxide reductase (N2OR) genes, and affected its denitrification by several secondary metabolites of plants

ダイズ茎疫病菌Phytophthora sojae及びホウレンソウ根腐れ病菌Aphanomyces cochlioidesの遊走子細胞は、宿主植物から滲出する二次代謝産物フラボノイドを認識し、被嚢化、発芽という感染時形態変化を起こす。被嚢化は物理的刺激によっても起こるが、宿主認識物質が存在しない場合には発芽せずに遊走子を再生するため感染には至らない。しかし、動植物の細胞内シグナル物質として知られている一酸化窒素(NO)によって宿主認識物質なしでも遊走子の被嚢化・発芽が促進されることが観察された。また、P. soae遊走子をNOの消去剤であるcarboxy-PTIOで処理すると発芽した菌糸の伸長が有意に阻害された。これらの結果は、菌糸の伸長にNOが関与していることを示している。また、被嚢化後、発芽または再生遊走子のどちらに分化するのかそのギアチェンジに関わる遺伝子を探索するため、発芽を誘引する宿主認識物質処理(A)と遊走子再生を誘引する物理的刺激(B)によって被濃化させた胞子に特異的に発現している遺伝子を調べた。その結果、(A)では細胞骨格維持に関わる膜タンパク質、(B)ではアクチン構築に関与するタンパク質をコードする遺伝子が発現していた。
本研究課題の遂行により、卵菌においてNO依存性シグナル伝達系が宿主感染機構に重要な役割を果たしている可能性が示唆され、宿主感染成立のキーステップである被嚢化から発芽への細胞分化に関わる遺伝子が見いだされた。これらの結果は感染システムのさらなる解明と新たな防除法の確立に応用できる重要な知見であると期待される。

植物病原性卵菌類であるAphanomyces及びPhytophthoraは、遊泳能力を持つ遊走子細胞を形成することにより宿主植物に到達し感染する。その際、遊走子は被嚢化しさらに被嚢胞子の発芽が起こる。この遊走子形態変化は宿主感染機構において重要な過程であるがその分子機構については不明な点が多い。本研究では、遊走子の形態変化分子機構解明とその制御に関わる基礎的知見を得ることを目的とし、動植物で様々な生理作用を示す一酸化窒素(NO)の遊走子被嚢化及び発芽に対する影響を調べた。
Aphanomyces cochlioides及びPhytophthora sojae遊走子を自発的NO発生試薬であるNOC5またはNOR3で処理したところ、被嚢化及び発芽率が有意に上昇した。また、哺乳類型NO合成酵素(NOS)の基質であるアルギニンでも遊走子の発芽促進が観察されたため、DOE Joint Genome InstituteのP.sojaeゲノムデータベースを用いNOS様遺伝子の探索を行ったところ、アミノ酸配列で70%の相同性を持つ遺伝子が存在した。しかし、この遺伝子はオキシダーゼドメインを欠いており、同遺伝子を導入した大腸菌ではアルギニン由来のNO生成活性は確認出来なかった。また、脱窒菌や一部の真菌では脱窒過程においてNOを生成することが報告されていることから、脱窒に関わる酵素群遺伝子についても検索したところ、亜硝酸をNOに変換する亜硝酸還元酵素と高い相同性をもつ遺伝子が見つかった。
本研究課題の遂行により、A.cochlioides及びP.sojae遊走子の被嚢化及び発芽機構にNOが大きな影響を与える事が分かった。卵菌類の遊走子は宿主植物に到達できなかった場合は被嚢化しても発芽せずに再度遊走子を作りだすが、NOによって遊走子を強制的に被嚢化・発芽させる"自殺発芽誘導法"等の新たな駆除法の開発への応用が期待される。

1.The zoospores of phytopathogenic Oomycete, Aphanomyces cochlioides show clear positive chemotaxis to the host-specific singanl substances. The reputed receptor for the host-specific attractant toward the zoospores of spinach root rot pathogen, A.cochlioides wsa surveyed by using a biotin conjugated azidoflavone as a probe and resulted in 40 and 70 kDa membrane proteins on electropholetic gel plates.
2.The events caused by signal transduction regarding the life-cycle development of a Peronosporomycete (Oomycete) Aphanonyres cochlioides has been studied by using microscopic techniques. An interesting difference in F-actin profiles was observe between two kinds of custospores, one developing ahead to hyphal germination and the other rejuvenating to regeneration of zoospores.
3.About 150 rhizoplane bacteria were isolated from host and non-host plants, and our dual culture bioassay revealed that more than 5 % of isolates caused severe morphological alterations on phytopathogenic Oomycete Aphanomyces cochlioides and the fungal growth was strongly inhibited. From these results, we proposed that this method is new and effective way to find biological control agents against soilbome phytopathogens.
4.Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone) known as the host-specific zoospore attractant for a spinach root rot pathogen has been isolated so far only from Chenopodiaceae plants, spinach, sugar beet, and Chenopodium album, however, in our recent survey of zoospore attractants in Amamthaceae plant, Celosia cristata revealed that one of the active princilpes was indeed cochliophilin A.

生物の種多様性は熱帯・亜熱帯域の低緯度地域で高く、高緯度地域になるに従って減少することが知られている。しかし、依然として種の多様性を生み出すメカニズムは不明である。本研究計画では、沖縄に自生しているクロトンを用いて、多様性創出における転移因子の役割について基礎的知見を得ることを目的とした。6系統のクロトンについて、ヨナグニサン(蛾)Mariner-Like Element(MLE)配列中の転移酵素に対するコンセンサスプライマー用いPCR増幅を行った。その結果、用いた全ての系統において予測される500bpのバンドが検出され、MLEの存在が示唆された。RNA型転移因子の一つであるTy1/Copiaの逆転写酵素の配列に対するdegenerate PCRをおこなった結果、約300bpのPCRクローンが得られ、ワタのTy1/Copiaレトロポゾンと68%の相同性を示した。マングローブを含む樹木性熱帯植物27種の中で、デイゴとフクギからクロトンと同様なMLEのPCRクローンが得られた。今回、同所的に生息する昆虫のMLEが植物であるクロトンに見いだされたことと、クロトン以外の熱帯植物にも同様な配列が認められたことは、MLEが種を越えて同所的に水平伝播していることを強く示唆している。
