摘要: Argonaute(AGO) 蛋白是生物体中普遍存在的一类相对分子质量较大(约105)、成员数量众多的蛋白,该家族在不同物种中高度保守,由可变N 端、PAZ、MID 和PIWI等结构域组成。AGOs通过与不同的sRNA形成复合体参与植物生长发育、形态建成、细胞增殖凋亡、病毒防御、逆境响应等多种生物过程。综述了植物AGO 家族的结构特点、分类、作用模式及其生物学功能,尤其在逆境胁迫响应中的功能,分析了存在的问题,并对发展趋势进行展望,旨在为今后深入研究植物AGO功能提供理论参考。

Abstract: Argonaute (AGO) proteins are large relative molecular weight (about 105 ) and numerous members that are ubiquitous in organisms. They are highly conserved among different species and composed of domains including variable N terminus, PAZ, MID and PIWI,etc.. AGO proteins were involved in many important biological processes such as plant growth and development, morphogenesis, cell proliferation and apoptosis, virus defense, and stress response through forming complex with different kinds of sRNA. This review mainly focused on the structural characteristics, classification, action patterns and biological functions of the AGO protein family in plants, especially their functions in response to biotic and abiotic stress, as well as the existing problems and prospects of the research, in order to provide a theoretical reference for future study on AGO function in plants.

Key words: argonaute proteins, small RNAs(sRNAs), stress response, biological function
