Grana-Localized Proteins, RIQ1 and RIQ2, Affect the Organization of Light-Harvesting Complex II and Grana Stacking in Arabidopsis

Abstract Grana are stacked thylakoid membrane structures in land plants that contain photosystem II (PSII) and light-harvesting complex II proteins (LHCIIs). We isolated two Arabidopsis mutants, reduced induction of non-photochemical quenching (riq1 and riq2), in which stacking of grana was enhanced. The curvature thylakoid 1a curt1a) mutant was previously shown to lack grana structure. ...
