Outline of Final Research Achievements

In this project, I investigated the molecular and logical mechanism of microtubule and cell wall patterning in xylem vessels, in which cell walls are deposited in highly ordered patterns. I revealed that ROP G proteins self-organize the domain patterns of active ROPs. I also found that the novel signaling pathway that promotes local deposition of cell walls at the edge of pits where ROPs are activated.

Academic Significance and Societal Importance of the Research Achievements

細胞壁の沈着パターンの制御は道管に限らず、さまざまな植物細胞の機能に欠かせない現象です。本研究の知見は植物細胞が組織特異的な細胞壁パターンを構築して個体発生を実行する仕組みの理解に繋がります。さらに、この知見を応用することで、有用植物の生育の改善や木質バイオマスの増産、有効利用につながる可能性があります。
