| Outline of Final Research Achievements |
Peroxisomes are organelles that is involved in various metabolic reactions. Peroxisome membrane proteins are responsible for maintaining peroxisome homeostasis. However, in plants, the selective transport mechanism of peroxisomal membrane proteins is not well understood. In this study, we performed live cell imaging analysis of various peroxisomal membrane proteins and found that peroxisomal matrix proteins are gradually accumulated in the lumen of preperoxisomal compartment-like structure to form mature peroxisomes.

| Academic Significance and Societal Importance of the Research Achievements |
ペルオキシソームは環境変化に応じて，分裂，増殖したり，逆に分解を受けたりすることが知られている．植物においてペルオキシソームの分裂機構や分解機構については明らかになっている一方で，ペルオキシソームの成長・新規形成機構についてはほとんど明らかになっていない．本研究によってペルオキシソーム形成機構の一端に迫ることができた．将来的には，本研究の成果を環境変化に応答したペルオキシソームのダイナミクスの解明につなげていきたい．
