| Outline of Final Research Achievements |
I have been engaged in a research analyzing plant embryogenesis using rice as a model. During a process to analyze rice embryo development, I have noticed that some RNA molecule could be very unstable. The process of turn-over of maternal RNA after fertilization is not well characterized in plant comparing to that in animal systems. Therefore, I tacked this issue and tried to contribute to breeding science through the understanding of molecular basis of gene expression at very early stages in plant embryogenesis.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、イネを用いて植物の初期発生を理解することを目的に行われた。植物の初期発生は、動物のそれに比べて理解が進んでおらず、基礎研究として生物を理解する上で重要な課題である。一方、植物の胚が含まれている種子は、人類が食糧として利用していることも多く、胚形成の理解が物質集積などに役立つ可能性も十分にある。このことから、本研究によるイネ胚の初期発生理解につながり、ひいてはイネ種子における効率的な遺伝子発現制御へと結びつくと期待される。
