    The short-lived radiocarbon, 11C, is generated as carbon dioxide gas by a cyclotron, collected, and immediately assimilated into the lupin of a legume plant, and a system was constructed to observe the subsequent transfer of 11C to the roots and secretion from the roots to the surrounding soil. The results of the study are shown in Table 1. PET was used for detection. The use of lupin revealed that large amounts of assimilates were secreted from specific root sites (cluster root) into the rhizosphere soil, but not similarly in all cluster roots, and only in certain cluster roots.

    By the strategic monitoring research focusing on dissolved radiocesium (r-Cs) in the highly contaminated area by the Fukushima accident, it was clarified that the generation of dissolved Cs-137 in a water body was directly caused by leaching from forest litter and elution from the bottom sediment in a dam lake. On the other hand, the effect of irrigation water on the r-Cs concentration in brawn rice was not clearly confirmed. The analysis based on the collected Cs-137 data widely measured in river waters in the affected area clarified that the distribution coefficient did not show a temporal trend although it showed a regional dependency. Additionally, land use type was found to be a control factor deciding the dissolved r-Cs concentration in a river.
    These results suggest that measuring dissolved r-Cs by setting the detection low limit at 0.01 to 0.1 Bq/L with reasonably narrowing the monitoring points is crucial as the mid- and long-term role of the monitoring in water environment.

    Based on this research subject, Hokkaido University CoSTEP resumed risk communication classes from fiscal 2016. 15 students from the Faculty of Agriculture, Engineering and Science and 7 from the high school teachers and private companies attended the classes. A total of 22 people attended in 3 years. The purpose of this class is to develop human resources who are responsible for risk communication. Every year in September, we visited the towns around the Fukushima Daiichi Nuclear Power Plant and conducted inspections and interviews about radiation risks. These results were reported on March 26, 2018 in Fukushima City sponsored by the Reconstruction Agency. We also presented at the 31st Japan Society for Risk Research (Fukushima meeting) on November 9, 2018 and other some meetings of the academic society of Japan. And we also published in Japanese Journal of Radiation Safety Management about the educational effects of this class.

    Assimilation of 11CO2 to shoot for visualization of the rhizosphere of the plant and utilized it to make clear the role of rhizosphere by the exact place of secretion to rhizosphere soil. In lupin, the signal which resisted the formation position of the cluster root was clearly observed, and it was confirmed that a part of assimilation product was secreted via a root in a short time in the rhizosphere soil translocated from the assimilated part in shoot. As for the Leguminous crops, absorbing ability of radiocesium under potassium deficient condition is known to be high. However, the detailed mechanism is unclear, but some compounds secreted by a root and/or microbial activity changed the physico/chemical properties of soil is guessed. Plural compounds except the organic acid were secreted by potassium deficient condition became clear. On the other hand, it became clear that microbial species composition was greatly fluctuated even if just after assimilation.

    This study investigated the factors affected to the difference in radioactive cesium (RCs) accumulation in grain between wheat varieties. ‘AU49’ had higher RCs concentration than ‘Shiroganekomugi’ in low exchangeable potassium condition in soil. On the other hand, ‘Shiroganekomugi’ had higher RCs concentration than in high exchangeable potassium condition in soil. The difference was affected by the transportability of RCs from shoot to grain. Transportability of potassium from root to shoot was higher in ‘AU49’ than in ‘Shiroganekomugi’. From these results, it was considered that potassium demand was higher in ‘AU49’ than in ‘Shiroganekomugi’. RCs is similar with potassium in chemical property. Higher demand of potassium in ‘AU49’ my be a reason that ‘AU49’ had higher grain RCs concentration than ‘Shiroganekomugi’ in low exchangeable potassium condition in soil.

    Green stem disorder (GSD) causes a serious problem in the soybean harvesting because seed coat surfaces are soiled and its quality is deteriorated during machine harvesting. The metabolite- and element-compositions in the stems of soybean RILs with different GSD sensitivity were examined using the metabolomics and ionomics technique to evaluate the relationship between the genetical traits and physiological mechanism of GSD insensitivity. In the sensitive RIL to GSD, the amino acid and organic acid metabolism were activated, results in the increase of nitrogen content of stems. It was suggested GSD was activated the nitrogen metabolism because the increase of the amount of translocation of the element to the stems, not to seeds.

    We focus on nitrous oxide emission during freeze and thaw process in the field, and to investigate the diversity and evenness of the soil microorganism, metagenomic and metatranscriptomic approaches were applied on DNA and mRNA levels. The results indicate that during the bio-geochemical process, it is rather evenness play an important role than diversity of species number, indicating that few number of species seems to be increased with the process. We have applied the Functional Single Cell separation technique and obtain several isolates which seem to grow and lead the process dominantly under the cold condition.

    We investigated bacterial communities in paddy rice with low (LN), standard (SN) levels of N fertilizer application. Metagenome analysis suggested shifts of bacterial communities between LN and SN root microbiomes. The abundances of functional genes for methane oxidation were significantly increased in LN root microbiome. Plants have mutualistic symbiotic relationships with microorganisms by CCaMK. We examined the effect of an OsCCaMK mutant (NE1115). The CH4 flux of NE1115 in the LN field was significantly higher than that of WT, although no difference was observed in the SN field. qPCR and 13C/15N isotopic determinations suggested that CH4 oxidation and N2 fixation were simultaneously activated in the root of WT rice in the LN field, and both processes are likely controlled by OsCCaMK. Metaproteome and CARD-FISH analyses demonstrated that both processes are mediated by type II methanotrophs inhabiting the vascular bundles and epidermal cells of the rice roots.

    The nutritional absorption and excretion by plant root systems are one of the most important functions for agriculture; however, they are usually hidden under the ground and hardly analyzed by direct observations.
    In this study, novel methods of live imaging and kinetic analysis of absorption / excretion by the root were developed based on current radiotracer imaging technologies such as PETIS. Moreover, some important nutritional features and functions of plant root have been elucidated by using the established methods. For example, cadmium absorption by oilseed rape plants was directly observed using the newly developed root-zone imaging method, and we found that treatment of glutathione, a common tripeptide in a wide variety of organisms, onto the root induces cadmium excretion to the nutrient solution and thus suppresses cadmium uptake to the aboveground parts. These results demonstrated that our new methods are highly promising in the plant and agricultural sciences.

    Short half-life period radio nuclei:^<11>C was introduced to the shoot as carbon dioxide by photosynthesis, then the distribution of ^<11>C to the rhizosphere was analyzed. It was demonstrated that the distribution was most pronounced to the rhizosphere very close to the area of lateral root. The analytical development of collection and analysis of root secreting low molecular compounds and high molecular compounds (proteins) were developed. Phylogenetical and functional analysis of microorganism from rhizosphere soil very close to the root was performed by using pyrosequencing method on microorganism DNA and the obtained result shows that some functional gene fluctuation may explain the difference of plant growth.

    Aluminum ion is a major factor to inhibit plant growth in acidic soils. Mechanisms of aluminum toxicity and tolerance in plants were examined, focusing on energy(sugar) metabolism in mainly cultured tobacco cell lines and tobacco plant. Our results suggest a novel aluminum tolerant mechanism which shifts energy metabolism from respiration to lactate fermentation so that the production of reactive oxygen species(ROS) via dysfunction of mitochondria under aluminum stress could be avoided.

    マメ科モデル植物のミヤコグサ(Lotus japonicus)の養分吸収変異体を獲得するために、これまでに確立した吸収元素の網羅的解析手法であるイオノーム手法を用いた。変異体のスクリーニング対象としてはEMS(ethylmethane sulfonate)処理を行った種子を自分たちで調整した約200系統およびミヤコグサバイオリソースセンターから提供された約7000糸統を用いた。スクリーニング対象とした元素は必須元素としてはB, Mg, K, Ca, Mn, Fe, Cu, Zn, Mo、非必須元素としてはAI, As, Na, Ni, Sr, Cd, Csであり、非必須元素は野生株の生育に障害が出ない程度のレベルで培養液に添加して栽培を行なった。栽培は一定の環境条件下で同時に200系統を栽培し、全ての個体の地上部を別々に分解をし、対象元素含有率の測定をICP-MSを用いて行った。 200系統全体を母集団として、その平均から3倍以上あるいは半分以下にいずれかの元素含有率が変動した場合に変異を生じている候補として選抜し、地上部を切除した後の根部から植物体を再生することで種子を獲得した。同様の操作を繰り返し4世代目にいたっても元素含有率に変動か生じることを確認した系統を変異系統とした。 2000系統から32の変異系統が獲得された。
    得られた変異体の中で一つの元素だけが変動している系統は少なく、その平均は4-5種類の元素が同時に変異していることが示された。また元素の種類によっては変動株が多く得られるものがあり、その逆も認められた。実際に獲得したMoの変異株は体内めMoトランスポーターに変異が生じていることが確認され、本手法の有効性が認められた。また、化学的性質の異なる元素が体内においで一定のバランスを持っで存在するイオンホメオスタシスの現象が認められ、変異によってこのバランスかくずれる可能性が初めて示唆された。

    Aluminum (Al) ion inhibits sugar uptake which leads to the inhibition of water uptake as well as cell elongation. Inhibition of sugar uptake by Al seems to be compensated by the stimulation of translocation of photosynthates. Novel strategy for Al tolerance differing from the known strategy based on the release of organic acid anions was found. Higher sterols in plasma membrane lipid layer of root-tip were demonstrated to be the cause of Al tolerance. Genomic and genetic approaches in Arabidopsis revealed that acid and Al tolerances were co-regulated by the same signal transduction pathway, but with the distinct functional genes for tolerance. Comparative microarray analysis showed that common alterations involved in the metabolisms of sugars and lipids contributed to P recycling. It was suggested that responses in flavonoids synthesis were specific in leguminous plants.

    When comparing the behavior of primary photosynthate between rice and soybean, a large amount of primary photosynthate is distributed to starch fraction especially in soybean. As the metabolic pathway regarding photosynthesis, glycolysis, TCA cycle, etc. are same between rice and soybean, the observed difference is assumed to be derived from the different size of the pool of assimilated compounds. To confirm the idea, several genes' expression which are working on metabolites partitioning are investigated at different growth stage. The obtained results support the photosynthate distribution pattern. A large distribution of primary phosynhtate into starch fraction indicate the importance of delivery system among cytosol, chloroplast, and vacuole, thus a new method is developed to separate these organelle without further enzyme reaction during extraction process. Non aqueous fractionation method was developed and applied to soybean leaf. Each fraction was further analyzed by metabolomics approach using gas chromatography mass spectrometry (GC-MS). The metabolomics approach allows us to identify and quantify about 130 compounds in the tissue.

    This study aimed to solve problems on acid soils for utilization as arable soils. Critical problems of acid soil are 1) toxicity of metallic ions and 2) phosphorus starvation. Some plant species have been developed some strategies to adapt on acid soils. We have shown that the several root exudates bring the tolerance to stresses on acid soils. Therefore, the secreting abilities of plant roots were investigated in this study.
    A gene for secretory acid phosphatase isolated from white lupin, which is well known as a phosphorus tolerative plant, was introduced into tobacco plants. The growth and phosphorus acquisition of transgenic plant were improved from wild type plants. To investigate the secreting ability of organic acid, which can liberate inorganic phosphate from sparingly soluble forms, malate exudation of Arabidopsis was chosen as a model. It was indicated that malate release was induced by the up-regulation of malate transporter protein. The induction of malate transporter expression by aluminum was specific in the root tips and internal tissues of roots, suggesting that the mechanism is regulated to minimize the carbon consumption. It is concluded that site-specific regulation of the transporters is required to improve the inorganic phosphate uptake ability.
    It was suggested that the specificities of mucilage, consisted of polysaccharides, in the root exudates differed among plant species. The highest affinities of mucilage of Melastoma malabathricum and maize were shown with trivalent and divalent cations, respectively. The affinity of mucilage of Melastoma malabathricum was high to aluminum ion, though the binding strength was quite lower than that of maize. It was supposed that not only the composition of sugar but also methylation of uronic acids were involved in the differences of adsorption specificity to the cation. Separation and purification of substances involved in the elongation of mycorrhizal hyphae was conducted. It was succeeded that an A2 fraction, which induced an elongation and secondary and further branching of mycorrhizal hyphae was obtained from root exudates of onion.

    Tropical peatland is important for net carbon (C) storage in the global land surface, but it is also believed to be a major emission source of CH4.Land resource exploitation and burning of peat increases C release from the peatland, and thus contributes to overall global warming. In order in discern the magnitude of agricultural and fire impacts in tropical peatlands on global warming, ground surface emissions of three major greenhouse gases (GHG), CO2, CH4 and N2O, were measured in various ecosystems including forests and agricultural fields, as well as fire-affected lands in Karampangan zone, near Plangka Raya, from 2001 to 2003.After forest burning, the GWP decreased in 32-42% of the GWP from the natural forest, with 99% of the GWP occurring from CO2 emission. However, no trees could absorb the CO2, so the CO2 emissions went directly to the atmosphere.CH4 was emitted from the burned peatland, while CH4 uptake was observed in both the natural and regenerated forests.
    The GWP in the agricultural field was approximately 2 times larger than that from the natural forest. CO2 emission in the agricultural field was about 5 times larger than that in Japanese crop fields and accounted for 50-90% of the GWP. The remaining GWP was contributed by N2O emission. The N2O emission was considerably high, accounting for 4-23% of the nitrogen (N) application rate of 626 kg N ha1 yr-1.This is probably due to high peat decomposition and high nitrification enhanced by high pH and high exchangeable Ca content us the agricultural fields.
    Magnitude of forest fire impact on global warming was much higher than agricultural impact. But nitrogen application in agricultural field, which may accelerate peas decomposition, enhanced N2O emission and deduced CH4 uptake.

    In this study, we cultured rot washings in nitrogen-free, soft gel medium as a primary screening of functional rhizoplane and/or rhizosphere microbes, and we efficiently and selectively obtained α- and β-proteobacteria to exclude saprophytic γ-proteobacteria. Those oligotrophic and/or diazotrophic bacteria were visualized their behaviors in the soft gel medium, including their biocomplex formation and tripartite partnerships. The bacterial flora propagated in the N-free soft gel medium of gellan gum base survived relatively longer in the medium at room temperature due to a biofilm-like colonization and quorum-sensing like dormancy. Thus, we were able to trail new area of functional rhizo-biocomplex connected to the study of behabior of rhizoplane microfloral communities. As a demonstration, we have isolated and sub-cultured two rhizoplane bacteria, Sphingomonas rosa and Burkholderia cepacia, from rhizoplane of Melastoma malabathricum, a representative acid sulfate soil-tolerant plant, and identified them with 16S rRNA gene sequencing and data base search. The S. rosa showed. abilities to alter rhizospherous conditions and also to enhance nitrogen supply from the rhizo-biocomplex in a sotrongly acidic conditions. Like S. rosa, many other Sphingomonas spp. often isolated from the rhizoplane of acid-tolerant plants in Kalimantan had characteristics of 1) contributing to reliving divert soil in the rhizosphere, 2) fixing nitrogen in the rhizoplane or at least adjusting conditions for nitrogen fixation, and 3) being regulated the microfloral population via Mg^<2+> in the rhizosphere. In addition, Sphingomonas spp. had tight partnerships and tripartite-like co-works in the rhizoplane and/or inner tissues of host plants. Sphingomonas spp. are thus expected to be a motive force for nitrogen circulation and high genetic diversity in the rhizo-biocomplex.

    Ontogenetic changes of photosynthesis (Pnet) of individual leaf were examined in relation with nitrogen content (Nc, mg g^<-1>) in individual leaf. During the lag phase of NC at the leaf expanding stage, CFR (net carbon flux rate) related negatively to Nc. since Pnet relates to photosynthates translocation from leaf (CFR,which was estimated by using isotope technique), it was assumed that CFR could be an indicator of net carbon efflux rate from leaf. After the lag phase of Nc, as Pnet related positively to Nc, CFR could be ascribed as follows ; CFR=CfxNc+CFR_0, where Cf and CFR_0 are coefficients. Therefore, Cf is coefficient of carbohydrate translocation rate per unit Nc. Nc is also expressed as a function of time as follows ; Nc= (Nc_0-Ncd) x exp (-Nf x t) +Ncd, where Nf is noefficient, t is days after leaf emergence, Nc_0 is the Cn of leaf at emergence, and Ncd is the Nc of dead leaf. Then net nitrogen exchange rate (NFR) is calculated as NFR=DELTANc/DELTAt=-Nfx (Nc-Ncd). Therefore, Nf is coefficient for nitrogen translocation rate per unit Nc.Thus, it is hypothesized that Cf and Nf are indicators for carbon and nitrogen efflux from individual leaf (carbon and nitrogen efflux rate per unit Nc), respectively. Cf (or DMf) increased exponentially with the increase of Nf, indicating that the net efflux of carbon and nitrogen interrelate closely. Accordingly, since Nf indicates net nitrogen efflux rate per unit Nc, CFR is regulated not only by Nc, but also by net nitrogen efflux (Nf) from individual leaf.
