000052985 520__ $$aPhotosystem II (PSII) complexes, which split water into oxygen, protons and electrons in photosynthesis, require light but are also inactivated by it. Recovery of PSII from photoinactivation requires de novo protein synthesis. PSII in capsicum leaf segments were photoinactivated in the absence of chloroplast-encoded protein synthesis. At large photon exposures and despite the absence of repair, a residual fraction of PSII remained functional, being ca 0.08–0.2 depending on the ease of gas exchange in the tissue. This study revealed that the residual functional PSII was photoprotected by both (1) reaction-center quenching of excitation energy by photoinactivated PSII even when little or no PSII activity was permitted, and (2) antenna quenching, which was dependent on a trans-thylakoid pH gradient sustained mainly by linear electron transport and facilitated by the residual functional PSII complexes themselves. Significantly, little or no contribution to photoprotection of PSII was observed from cyclic electron flow around PSI. Further, the small residual functional PSII population was critical for recovery of the photoinactivated PSII complexes. Thus, photoinactivated and residual functional PSII complexes in leaves play a mutually beneficial role in each other’s ultimate survival.
