  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.

  2. Data show that light harvesting complex I (Lhcb1) and light harvesting complex II (Lhcb2) have different phosphorylation levels.
    Title: Phosphorylation of the Light-Harvesting Complex II Isoform Lhcb2 Is Central to State Transitions.
  3. investigated the phosphorylation level of the Lhcb1 and Lhcb2 isoforms that compose LHCII in PSI-LHCII and PSII-LHCII supercomplexes purified from WT and state transition mutants of Arabidopsis thaliana
