摘　　要：光合作用是植物最基本的生命活动之一,逆境胁迫可通过影响光合作用抑制植物生长.光捕获叶绿素a/b结合蛋白(light-harvesting chlorophyll a/b-binding proteins,Lhc)是光合作用中的一个重要成员,有大量研究表明,Lhcs及其编码基因在植物的抗逆性方面起到了不可忽视的作用,如在干旱胁迫下使抗氧化酶活性增加,通过激活脱落酸信号通路来促进耐寒性,在不同的逆境胁迫下通过表达量上调或者下调影响相关功能的蛋白质以达到最终的抗逆效果.因此,Lhc基因对于植物的生长乃至生存具有重要的意义.对近年来Lhc基因在分类、功能以及在环境胁迫中的作用等方面的研究结果进行概括总结,为进一步研究Lhc基因提供理论基础.Photosynthesis is one of the most basic life activities of plants,stresses can inhibit plant growth though affecting photosynthesis.Light-harvesting chlorophyll a/b-binding protein(Lhc)is an important member of photosynthesis,a large number of studies have shown that Lhcs and the genes encoded them play nonnegligible roles in plant stress resistance aspects,such as increasing the activity of antioxidant enzymes under drought stress,promoting cold tolerance by activating abscisic acid signaling pathway,and achieve the final stress resistance effects by up-regulating or down-regulating the expression of proteins with related functions under different stresses.Therefore,Lhc genes are of great significance for growth and even survival of plants.Summarized there searched results of the classification,functions and role of Lhc genes in environmental stresses,and provided theoretical basis for further studies of Lhc genes.
