Photosystem 2 photoinactivation (PS2PIA) is characterized by a selective and roughly parallel decline of PS2 electron transport activity and of the variable component of PS2 fluorescence (Fv). It is an important component of photoinhibition, i.e. injury to photosynthetic apparatus induced by very high irradiances (see (1) for review). In isolated thylakoids and in chloramphenicol treated photosynthesizing cells PS2PIA can be observed down to irradiances around and below saturation (2, 3, 4). This suggests that it accompanies photochemistry of photosynthesis and under normal conditions its consequencies become repaired by proteosynthe sis on 70S ribosomes.
