Abstract:

Photosynthetic organisms are usually exposed to fluctuating light, and therefore they evolved mechanisms enabling fast acclimation to changing light conditions. Among them, two important ones are energy-dependent quenching of excited chlorophyll (qE) and state transitions (ST). qE is a photoprotective mechanism regulated by pH gradient across thylakoid membranes, in which excessive energy is dissipated as...
