PsbS-dependent enhancement of feedback de-excitation protects photosystem 11 from photoinhibition

Li, Xiao-Ping; Muller-Moule, P; Gilmore, Adam; Niyogi, Krishna

Description

Feedback de-excitation (qE) regulates light harvesting in plants to prevent inhibition of photosynthesis when light absorption exceeds photosynthetic capacity. Although the mechanism of qE is not completely understood, it is known to require a low thylakoid lumen pH, de-epoxidized xanthophylls, and the photosystem II protein PsbS. During a short-term 4-h exposure to excess light, three PsbS- and qE-deficient Arabidopsis thaliana mutants that differed in xanthophyll composition were more...[Show more]
