摘要：In the unicellular cyanobacterium Synechocystis sp. PCC 6803, the mrgA gene is part of the PerR regulon that is upregulated during peroxide stress. We determined that an mrgA mutant was highly nsitive to low peroxide levels and that the mutant upregulated a gene cluster ( sll1722-26 ) that encoded enzymes involved with exopolymeric substance (EPS) production. We made mutants in this EPS cluster in both a wild type and mrgA background and studied the respons to oxidative stress by measuring cell damage with LIVE/DEAD stain. We show that Synechocystis sp. PCC 6803 becomes highly nsitive to oxidative stress when either mrgA or the sll1722-26 EPS components are deleted. The results suggest that the deletion of the EPS cluster makes a cell highly susceptible to cell damage, under moderate oxidative
