摘要
概述了植物光合作用光抑制的研究进展 ,包括造成光抑制和光氧化的活性氧的产生和作用机理 ,光抑制的作用部位 ,以及光保护机制等 ,着重从三个方面讨论了植物抗光抑制的保护机理 :与光系统Ⅱ天线以及叶黄素循环相关的热耗散途径 ,包括光呼吸、H2 O_H2 O循环和环式电子传递在内的电子传递途径 。
Recent progress in studies on photoinhibition of plant photosynthesis was summarized in this review, including the generation and role of the reactive oxygen species which might lead to photoinhibition and photooxidation, the targets of photoinhibition, and the mechanisms of photoprotection. Three proposed mechanisms for protection of plant from photoinhibition were discussed: thermal dissipation which relates to the photosystem Ⅱ antenna and xanthophyll cycle; electron transport pathway including photorespiration, H 2O_H 2O cycle and cyclic electron flow; and the scavenging system for reactive oxygen species.
