| Outline of Final Research Achievements |
Plants produce abundant oxygen and Reactive Oxygen Species (ROS) by photosynthesis. To protect themselves from oxidative stress, several ROS-scavenging system are identified in chloroplast of plants. Recently, several works indicate that peroxiredoxin-family proteins function in ROS-scavenging system of chloroplast. In this study, we evaluated physiological impacts for peroxiredoxins in ROS-scavenging system of chloroplast.

| Academic Significance and Societal Importance of the Research Achievements |
ペルオキシレドキシン のROS 消去系に対する生理的な寄与が明らかになれば、葉緑体ROS消去メカニズムで重要な役割を担うシステムが判明し、葉緑体ROS消去系に関する理解が進む。また、陸上植物の葉緑体における抗酸化システムについて、生理的意義の理解を深めることができる。これらのことが明らかになることで、植物の機能改良に向けた技術開発のための基礎的知見となるはずである。
