Photosynthetic activity of the mutants compared to the WT. (A) Decline of the net oxygen evolution of cultures adapted to control light (400 μmol m^-2 s^-1), when exposed to high light (2500 μmol m^-2 s^-1) during the measurement. (B) Net oxygen evolution rate at control light and (C) average respiration rate in the dark before and after the high light treatment (D) Non photochemical quenching and (E) photosynthetic yield under control light and after one hour of high light treatment.
