| Outline of Final Research Achievements |
We identified several factors related to hypersensitive response in plant defense using proteomic analyses and forward genetic approaches. These factors involved in development of chloroplasts. And they are required for enhancing the signal transduction pathways in hypersensitive response. The identified proteins might be the major components which presents on chloroplasts as a platform for activating signal transduction pathways .

| Academic Significance and Societal Importance of the Research Achievements |
植物ウイルス病害は，他の微生物病害と異なり，農薬による防除が難しく，植物の病害抵抗性機構を利用した新たな病害防除技術の開発が求められている．病害抵抗性機構における葉緑体の機能は未だ明らかになっていない部分が多く，ウイルス抵抗性の全容解明に向けて，本研究では，病害抵抗性に関与するタンパク質として，葉緑体の形成に必要なタンパク質を複数同定することができ，抵抗性反応全容解明に向けた端緒を得た．
