| Outline of Final Research Achievements |
Reduction of grain quality and yield of rice due to environmental stress such as global warming is a big social problem. In this study, we sought to elucidate the function of autophagy in improving the quality and yield of rice. We discovered that autophagy is induced at a specific stage in the most inner layer of anthers, which is crucial for pollen maturation. We also discovered that grain quality is reduced in autophagy-defective mutant, suggesting critical importance of autophagy during seed maturation.

| Academic Significance and Societal Importance of the Research Achievements |
オートファジー(細胞内自食作用)が、花粉の成熟や種子登熟における代謝の制御に重要な役割を果たすことが明らかとなった。この成果は、植物におけるオートファジーの新規の役割を提唱すると共に、オートファジーを制御することにより、地球温暖化等の環境ストレスによる収量低下や穀物種子の品質低下を防止する技術の開発に繋がる可能性を示唆している。環境にやさしい農業への道を開き、食糧・環境・エネルギー問題の解決への一歩となることが期待される。
