The sll1961 gene was reported to encode a regulatory factor of photosystem stoichiometry in the cyanobacterium Synechocystis sp. PCC 6803. We here show that the sll1961 gene is also essential for the phycobilisome degradation during nitrogen starvation. The defect in phycobilisome degradation was observed in the sll1961 mutant despite the increased expression of nblA, a gene involved in phycobilisome degradation during nitrogen starvation. Photosystem stoichiometry is not affected by nitrogen starvation in the sll1961 mutant nor in the wild-type. The results indicate the presence of a novel pathway for phycobilisome degradation control independent of nblA expression.
