Thermo-optically induced structural reorganizations have earlier been identified in isolated LHCII, the main chlorophyll a/b light harvesting complexes of Photosystem II, and in granal thylakoid membranes [Cseh et al. (2000) Biochemistry 39: 15250-15257; Garab et al. (2002) Biochemistry 41: 15121-15129].

- The LHCIIb complex in photosystem II undergoes light-induced reversible structural changes that contrast with its usual trimeric organization observed in the dark.
- These changes involve monomerization and the release of Mg ions, which is explained by a theoretical model that suggests temperature fluctuations contribute to structural transitions.
- The formation of monomers enhances the nonphotochemical quenching of chlorophyll a and may play a role in the degradation and regulation of light harvesting under excessive light conditions.
