State transition in blue-green algaSynechocystis PCC 6803

  • Junjiang Shen

The mechanism of state transition in blue-green algaSynechocystis PCC 6803 was investigated by using modulated fluorescence. NaF, an inhibitor of phosphatase, did not inhibit state II to state I transition. Rotenone, a specific inhibitor of NAD(P)H ubiquinone reductase, stimulated transition from state II to state I in dark. The results suggest that state transition in blue-green algaSynechocystis PCC 6803 is controlled by redox state of plastiquinone pool, but not by the phosphorylation of thylakoid membrane proteins.
