Outline of Final Research Achievements |
Reactive oxygen species which is one of the toxic molecules is important in seed germination of wheat and barley. In this study, we identified the ABA metabolism gene and RRGs (responsive genes of reactive oxygen species) as response genes to ROS and clarified the role of these genes in seed germination and dormancy.

Academic Significance and Societal Importance of the Research Achievements |
植物にとって、種子発芽は一生の幕開けとなる神秘的な生命現象であると同時に、農作物にとって収量や品質に直結する極めて重要な農業形質でもある。本研究は、農学・植物学にとって重要な種子休眠・発芽機構に、これまで悪者とされていた活性酸素が重要な役割を担っていることを明らかにした世界的にも非常に貴重な研究成果である。
