| Outline of Final Research Achievements |
During leaf senescence, degraded proteins are translocated from lower leaves to upper leaves. However, little is known concerning the mechanisms of the protein degradation. We have focused chloroplast, which includes 80% of the total leaf proteins; particularly the antenna proteins in Photosystem II, main membrane protein, on the thylakoids were studied. We consequently revealed the composition changing in Photosystem II is controlling the activity of the protease to the antenna proteins.
