| Outline of Final Research Achievements |
In plants, chloroplasts are exposed to the damage caused by sunlight during photosynthesis-dependent growth. After photooxidative damage, chloroplasts are degraded in their entirety via an autophagy pathway termed chlorophagy. This study addressed the induction mechanisms and molecular players for chlorophagy that degrades photodamaged chloroplasts. Through the combination between reverse genetics approaches and microscopy observations, we revealed that what types of chloroplasts are targeted as a selective substrate of chlorophagy. Furthermore, to find the unknown genes regulating chlorophagy, we performed forward genetics analyzes, and identified some candidate genes that are specifically required for chlorophagy.
