| Outline of Final Research Achievements |
Chloroplasts in land plants, which originate from endosymbiosis of cyanobacteria, are the organelles that develop thylakoid membranes in response to light and are responsible not only for the synthesis of photosynthates but also for the synthesis of various compounds like lipids, amino acids and phytohormones. As a site of light energy conversion, chloroplasts are susceptible to damage caused by excess light, and the quality control and environmental adaptation functions related to chloroplast maintenance also have a significant impact on plant growth. Our previous studies have revealed the importance of the processive degradation of macromolecules such as proteins and nucleic acids for chloroplast homeostasis. In this study, we conducted genetic and physiological studies to understand the new functions of chloroplasts through these processive degradation mechanisms.
