Oxygen evolution in the F10A mutant underwent rapid inactivation in high light, which did not recover during darkness, but rapid recovery of PS II activity was induced by subsequent low\u2010light exposure. Lincomycin added before the high\u2010light treatment prevented the recovery of PS II activity under low light, whereas the addition of lincomycin after the high\u2010light treatment did not block recovery. These findings indicate exchanging PsbE:Phe10 for Ala resulted in the formation of a dark\u2010stable inactive PS II complex upon exposure to high light and that light\u2010induced protein synthesis during high\u2010light exposure conditioned the inactivated PS II for recovery via a process triggered by low light. Ala substitutions introduced at the neighboring PsbE:Pro9 and PsbE:Ser11 residues did not introduce the high\u2010light sensitive phenotype, indicating that the sensitivity to high light and the formation of the dark\u2010stable PS II complex were unique to the PsbE:F10A strain.\n
