| Redox control of phosphorylation of chloroplast light-harvesting complex II and of reaction centre gene expression. Control of photosystem stoichiometry is assumed to result from redox effects on expression of genes for components of the two photosystems. In this scheme, photosystem stoichiometry adjustment and fine-tuning of light-harvesting by protein phosphorylation are complementary adjustments to the same redox signal. "LHC" is LHC II in chloroplasts, and a putative phycobilisome component in cyanobacteria and red algal plastids. |
