    1. The results corroborate a localization of PsbS in PSII supercomplexes and support the model that the light activation of NPQ is based on the monomerization of dimeric PsbS and a light-induced enhanced interaction of PsbS with Lhcb1, the major component of trimeric light-harvesting complexes in PSII.
