Plant annexins are evolutionary conserved protein family widely exist in almost all plant species, characterized by a shorter N-terminal region and four conservative annexin repeats. Plant annexins have Ca channel-regulating activity and peroxidase as well as ATPase/GTPase activities, which give annexins functional specificity. They are widely involved in regulating diverse aspects of biochemical and cellular processes, plant growth and development, and responses to biotic and abiotic environmental stresses. Though many studies have reviewed the function of annexins, great progress have been made in the study of plant annexins recently. In this review, we outline the current understanding of basic properties of plant annexins and summarize the emerging advances in understanding the functional roles of annexins in plants and highlight the regulation mechanisms of annexin protein in response to stress especially to salt and cold stress. The interesting questions related to plant annexin that remain to be further elucidated are also discussed.
植物 annexin 是进化上保守的蛋白质家族，广泛存在于几乎所有的植物物种中，其特征是 N 端区域较短，有四个保守的 annexin 重复序列。植物 annexin 具有 Ca 通道调节活性和过氧化物酶以及 ATPase/GTPase 活性，这赋予 annexin 功能特异性。它们广泛参与调节生化和细胞过程的多个方面、植物生长发育以及对生物和非生物环境胁迫的反应。尽管许多研究已经综述了 annexin 的功能，但最近在植物 annexin 的研究方面取得了很大进展。在这篇综述中，我们概述了对植物 annexin 基本特性的现有认识，并总结了对 annexin 在植物中的功能作用的理解的新进展，并强调了 annexin 蛋白在应对胁迫，特别是盐胁迫和冷胁迫时的调节机制。还讨论了与植物 annexin 相关的一些有趣问题，这些问题仍有待进一步阐明。
