14-3-3 proteins (14-3-3s) are highly conserved regulatory proteins that are uniquely eukaryotic, and deeply involved in protein-protein interactions that mediate diverse signaling pathways. In plants, 14-3-3s have been validated to regulate many biological processes, such as metabolism, light and hormone signaling, cell-cycle control and protein trafficking. Recent years we have also witnessed an increasing number of reports describing the functions of 14-3-3s in plant stress responses through interactions with key proteins in both biotic and abiotic stresses. In this review, we highlight the advances that have been made in investigating the roles of 14-3-3s in plant abiotic stress tolerance. These advances provide a framework for our understanding of how signals are integrated to perceive and respond to the abiotic stresses in plants.
14-3-3蛋白是高度保守的调控蛋白，是真核生物所特有的，并且深度参与介导多种信号通路的蛋白质-蛋白质相互作用。在植物中，14-3-3蛋白已被证实可调节许多生物学过程，如代谢、光和激素信号传导、细胞周期控制以及蛋白质运输。近年来，我们也目睹了越来越多的报道描述14-3-3蛋白通过与生物和非生物胁迫中的关键蛋白相互作用在植物胁迫反应中的功能。在本综述中，我们重点介绍了在研究14-3-3蛋白在植物非生物胁迫耐受性中的作用方面所取得的进展。这些进展为我们理解植物如何整合信号以感知和应对非生物胁迫提供了一个框架。
