摘　要：

植物光系统可以利用光能进行光合作用, 但过量的光能会对光系统造成损伤。因此, 植物逐渐进化出一套精细的适应机制以避免高光损伤, 维持高光胁迫下光系统的正常功能。本文主要综述近年来植物光系统适应机制的研究进展, 包括植物对光损伤的防御、保护和光系统II (PSII)损伤修复, 并展望相关研究前景。

Abstract:

Photosystem can utilize light energy for photosynthesis in plants, but excess light would damage photosystem. Thus, plants have therefore evolved diverse adaptive mechanisms to avoid the damage from excess light, maintaining the normal function of photosystem. This review focuses on the process of mechanisms of adaptation, including the defense and protection to excess light and repair of photodamage. Moreover, this review also provides prospects for future research in studying photosystem adaptation.

Key words: photosystem; defense; protection; damage and repair
