Research Projects

  • 気中汚染物質に対する植物防御の統合的システムに関する分子生理学的研究

    Grant number:18F18391  2018.11 - 2021.03

    Plants protect themselves from harmful gases through closing stomata and/or detoxification. Sulfur dioxide (SO2) is a harmful gas known to induce stomatal closure. However, the cellular mechanism mediating SO2-induced stomatal closure remains obscure.
    To shed lights on the roles of phytohormones in SO2-induced closure, we examined the temporal patterns of nine phytohormones, gibberellin A1, A4, abscisic acid, salicylic acid, jasmonic acid (JA), jasmonoylisoleucine (JA-Ile), indoleacetic acid, zeatin and isopentenyladenine in SO2-treated plants. The contents of JA and JA-Ile continuously increased.
    Through comparison of estimated atmospheric concentrations of these gases along the evolution of plants, we propose that this difference is attributed to historical difference in the gas compositions in the atmosphere. Sulfite oxidase (SO) is the key enzyme in SO2 detoxification. Phylogenetic analysis revealed that SO has evolutionally developed dating back at least to green algae. We understand that the detoxification mechanism against SO2 evolved earlier than stomatal defense.
    We hypothesized that the action of SO2 inducing stomata is through acidosis. AtClCa is a nitrate/proton antiporter mediating pH stabilization of guard cells. We found that clca mutant guard cells demonstrated stronger resistance to SO2 than guard cells of wild-type plants.

  • Construction of an efficient CO2 influx pathway using synthetic biology and improvement of photosynthetic capacity based on this approach

    Grant number:18H02169  2018.04 - 2022.03

    Grant amount:\17160000 ( Direct expense: \13200000 、 Indirect expense:\3960000 )

    This study aimed at establishing a molecular basis for artificial construction of an efficient CO2 influx pathway in plants. First, we co-expressed a chimeric protein fused with cyanobacterial bicarbonate transporter and a protease in plants, and succeeded in accumulating the bicarbonate transporter as an authentic protein in chloroplasts. In addition, by constructing multiple bicarbonate transporter chimeric genes fused with protein A or GFP, two types of bicarbonate transporters could be simultaneously accumulated in chloroplasts at high levels. In addition, we identified proteins that interact with GLK1 protein and analyzed the regulatory mechanisms that may affect the CO2 uptake capacity of bicarbonate transporters.

  • Physiological and molecular study of CO2 permeable aquaporins

    We established yeast screening system to identify CO2 permeable aquaporins. Among 69 aquaporins from rice, barley and Arabidopsis, 18 aquaporins were identified as putative CO2 permeable aquaporins. One of these aquaporins, OsTIP2;2 was detected around chloroplasts and some organelles (possible mitochondria), and seemed to have a function to supply CO2 intracellularly to inner chloroplast.

  • 高二酸化炭素環境下における二酸化炭素透過性アクアポリンの活性制御

    アクアポリンは水などの非イオン性極性低分子の生体膜透過性を司るチャネルタンパク質であり,CO2を透過する分子も存在する.アクアポリン遺伝子はひとつの植物ゲノム上に30以上あるが,CO2を透過する分子種は未だ不明だった.本研究では,アクアポリンのCO2透過性および非透過性分子種を同定するとともに,CO2透過性に関わるアミノ酸のひとつを同定した.
    本研究以前は,PIP1型アクアポリンが主にCO2を透過するとされていたが,昨年度の本研究によりPIP2型アクアポリンに二酸化炭素透過性の高い分子が多数存在することを発見していた.本年度はさらにオオムギの二酸化炭素透過性を詳細に解析した結果,PIP2;1, PIP2;2, PIP2;3, PIIP2;5はCO2を透過し,PIP2;4はCO2を透過しないことが確定した.PIP2;3とPIP2;4はアミノ酸がわずかに6つ異なることから,相互にアミノ酸置換を行うことでCO2透過性の差異に関わるアミノ酸を決定した.PIP2;3の254番目のイソロイシン残基がPIP2;4のようにメチオニンに変わるとCO2透過性を喪失するが,水透過性には違いが見られなかった.この研究はアクアポリンのCO2透過性の分子構造的機構を明らかにした世界初の例である.

    Stomatal movement is closely involved in drought tolerance and absorption of nutrients. In this study, we analyzed mechanism of stomatal closure induced by abscisic acid to find new signaling components including proteins and low molecule compounds.
