Turnover rates of photosynthetic proteins indicate a correlation with photosynthetic capacity under state transitions.

Plant physiology - 2 Mar 2026

Li Yuanyuan, Liang Han, Hou Yuqi, Duncan Owen, Millar A Harvey, Li Lei

Abstract excerpt

State transitions in algae and higher plants involve the phosphorylation and dephosphorylation of light-harvesting complex II, which are regulated by the kinase STN7 and phosphatase TAP38/PPH1. We systematically measured thylakoid protein turnover in stn7-1 and tap38-1 Arabidopsis (Arabidopsis thaliana) mutants, which are locked in permanent State I and State II, respectively. Although the abundance of...
