Outline of Final Research Achievements |
Plant mitochondria is an important organelle for plant growth and development. Mitochondria has own gene expression system and this is tightly regulated at post-transcriptional level. However, the mechanism of post-transcriptional regulation is still unknown. In this study, we identified new factors involved in organelle RNA regulation such as splicing and RNA stability.

Academic Significance and Societal Importance of the Research Achievements |
ミトコンドリアの正常な機能発現は植物の生育に必須であるにも関わらず、その遺伝子発現機構は未だ不明な点が多い。ミトコンドリア遺伝子発現に働く因子を明らかにすることは、ミトコンドリアの複雑な遺伝子発現システムの理解につながるため、学術的意義は大きい。また、ミトコンドリアの遺伝子発現システムが解明されれば、ミトコンドリア機能増強による有用作物の作出が期待される。
