摘要
在大多数逆境下,植物只有PSII发生光抑制,而PSI比较稳定。植物PSI光抑制主要发生在低温-光胁迫下。PSI发生光抑制后恢复非常缓慢,光抑制后PSI活性的恢复是低温胁迫后光合作用恢复的限制因素。本文探讨了PSI光抑制及光抑制后PSI活性的恢复过程,包括:PSI光抑制发生的决定因素、PSI低温光抑制的机理、PSI的光破坏防御机制和发生光抑制后PSI活性的恢复。
Photosystem II （PSII） in plants is the primary target for photoinhibition, but PSI is more stable under most abiotic stress. However, chilling-light treatment causes PSI photoinhibition. After chilling-light stress, PSI activity recovers very slowly, so the recovery of PSI is the limiting factor for the recovery of a whole photosynthetic apparatus after chilling-light stress. This review focused the PSI photoinhibition and its recovery after photoinhibition, including： the requirements for the PSI photoinhibition; mechanism of the PSI photoinhibition; photoprotection of PSI; PSI recovery after photoinhibition.
