【 摘 要 】

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.
