Decay kinetics of the YDox EPR signal in thylakoids. Thylakoids were isolated from the PS I-less strain (open squares) and the Rg2/PS I-less strain (solid squares) of Synechocystis sp. strain PCC 6803. Illumination was turned off at time zero. The EPR signal intensities were similar in both strains and were normalized to 1.0 at the end of illumination. a.u., arbitrary units.
