Outline of Final Research Achievements |
Phosphatidylinositides are essential for cellular dynamics of plants. We found that one of Phosphatidylinositides, PI(4,5)P2 accumulated in extra-invasive-hyphal membrane during Colletotrichum infection. Overexpressing PIP5K (an enzyme for PI[4,5]P2 production) caused higher susceptibility to Colletotrichum than wild type. These results suggest that Colletotrichum induces the PI(4,5)P2 production in plants for its infection.

Academic Significance and Societal Importance of the Research Achievements |
本研究により,炭疽病菌感染のためには,植物細胞内で,微量脂質であるPI(4,5)P2の集積が重要であることが明らかになった.PI(4,5)P2は植物の生存に必須の脂質であるため,炭疽病菌はそのシステムを効率よく乗っ取り,感染を成立させていることが示唆された.炭疽病菌の防除ためには,PI(4,5)P2の量を適切に保つ必要があることが本研究より示された.
