Light-induced modification of PSII complex was characterized in the cyanobacterium Synechococcus sp. PCC7942 treated with either DCMU or BNT. The irradiance response of photoinactivation of PSII oxygen evolution indicated a BNT-specific photoinhibition that saturated at relatively low intensity of light. This BNT-specific process was slowed down under anaerobiosis and was accompanied by the oxygen-dependent formation of a 39kDa D1 protein adduct, and was not related to stable QA reduction or the ADRY effect.
