Evidence that cytochrome b(559) is involved in superoxide production in photosystem II: effect of synthetic short-chain plastoquinones in a cytochrome b(559) tobacco mutant

Light-induced production of superoxide (O(2)(•−)) in spinach PSII (photosystem II) membrane particles was studied using EPR spin-trapping spectroscopy. The presence of exogenous PQs (plastoquinones) with a different side-chain length (PQ-n, n isoprenoid units in the side-chain) enhanced O(2)(•−) pro...
