Outline of Final Research Achievements

A stereoisomer library of phytotoxins was constructed by chemical synthesis, and a comprehensive evaluation of their affinity for phytohormone receptor subtypes and their biological activity was conducted in an international collaboration with CNB-CSIC, Spain. The stereoisomer library was evaluated using three plant species, Arabidopsis thaliana, tomato, and rice, and we succeeded in finding stereoisomers each showing unique selective affinity to nuclear receptor subtypes.
In this study, we focused on stereoisomers that showed affinity to the receptor subtypes in Arabidopsis thaliana and analyzed their mechanisms of action in detail. As a result, we succeeded in developing molecules that selectively activate receptor subtypes of phytohormone receptors that are involved in the induction of plant resistance to microbial infection.The molecule selectively activates only a portion of phytohormone signaling, while suppression of gene expression does not occur to any degree.

Academic Significance and Societal Importance of the Research Achievements

通常では、植物の病原菌感染耐性は、植物の生長阻害とトレードオフの関係にあるが、本手法ではこれらを切り離して活性化できることが明らかになり、既存の遺伝学的手法と比較して、ケミカルバイオロジー手法の優れた点を示すことができた。本分子は植物ホルモンのシグナル伝達の内の一部のみを選択的に活性化する一方で、遺伝子発現の抑制は歩と度起こさないことが明らかになった。これによって、植物の生長防御には、細胞壁の生合成を抑制する遺伝子群の発現が関与することが明らかになった。
