Restoration of light induced photosystem II inhibition without de novo protein synthesis.
Illumination of isolated spinach thylakoid membranes under anaerobic conditions gave rise to severe inhibition of photosystem II electron transport but did not result in D1-protein degradation. When these photoinhibited thylakoids were incubated in total darkness the photosystem II activity could be fully restored in vitro in a process that required 1-2 h for completion.
