摘要

许多生物及非生物胁迫都会引起植物的氧化胁迫, 参与植物氧化胁迫反应组分的鉴定备受人们的关注。拟南芥SRO家族成员包括AtRCD1、AtSRO1、AtSRO5等, 调节植物对氧化胁迫的反应。AtSROs参与植物正常的生长发育, 同时在植物应对干旱、盐、重金属等胁迫反应中扮演重要角色。AtSROs存在保守的PARP、RST等特殊功能区, 推测其可能具备蛋白的转录、调节、修饰等功能。文章就拟南芥SRO家族成员的基本状况, 在植物生长发育及应对非生物胁迫反应中的作用进行概述, 为进一步研究AtSROs的生物学功能提供理论基础。

Abstract

Many biotic and abiotic stresses can cause oxidative stress in plants. The identification of components involved in plant response to oxidative stress has attracted wide attention. The members of AtSRO family, including AtRCD1, AtSRO1, and AtSRO5, regulate plants’ response to oxidative stress. AtSROs participate in plant normal growth and development, and play important roles in plant response to stresses, such as drought, salt, heavy metal, and so on. In addition, AtSROs possess some special domains, including PARP and RST. It is speculated that AtSROs may function in regulating protein transcription, adjustment, and modification. This review highlights some recent progresses, such as basic situation of AtSROs, effects of AtSRO family proteins on plant growth and response to abiotic stress, which will provide a theoretical basis for further studying on biological functions of AtSRO.
