| 摘 要： | 光抑制是目前高等植物光合作用研究中的热点，近此年来无论是对其本质的认识，还是机理研究都已取得很进展。本文首先简要回顾了光抑制研究发展的历程，阐明现代光抑制理论包括耗散过剩光能的光保持机制运转和过剩光能对光合机构的破坏两个方面。然后，应叶黄素循环、Ｍｅｈｌｅｒ反应、光呼吸、ＬＨＣⅡ磷酸化、ＰＳⅡ光化学活性下降以及由类胡罗卜素、Ｃｙｔｂ－５５９参与的一些主要光保护机制作了综述，着重论述了其作用机理及研

| Abstract: | Photoinhibition is currently the highlight of photosyn thesis research of higher plants. Great progress in the the mechanism of photoinhibition has been made in recent years. In this article, we briefly review the history of photoinhibition research and elucidate the moder n photoinhibition theory, which comprises two aspects: dissipation of excess pho ton energy and damage of photosynthetic apparatus caused by excess photon energy . The xanthophyll cycle, photorespiration, LHCII phosphorylation, PSII photoche mical reactivity and other major photoprotective mechachisms involving caroteno id and Cytb-559 are discussed, with recent advances in studies on these photoprotective mechanisms highlighted. Finally, the current view on the o rig inal destructive point and the new theory on photodamage are summarized. |
