摘　　要：植物脱水素(dehydrins)是一种广泛存在于生物体中的亲水性蛋白,类型复杂且组织表达模式和亚细胞定位多样。近年来,随着脱水素生物学功能研究的不断深入,发现其参与植物激素响应、极端环境应答和免疫防御反应等多个途径,在维持植物细胞正常生理状态和功能中发挥重要作用。本文简要介绍了脱水素的蛋白质结构,对脱水素在不同生物学途径中的功能和作用机制及其表达调控的研究进行了系统综述,为深入了解脱水素基因家族在植物生长发育和与环境互作中的生物学功能提供参考。Dehydrins are a complex class of highly hydrophilic proteins that are among the most commonly observed proteins,possessing different tissue expression patterns and subcellular localization.Being intensively studied in the biological functions for the past few years,dehydrins have been found to modulate these responses of plants to hormone,extreme environment and immune defense.In addition,dehydrins have crucial roles in maintaining normal physiological state and function of plant cells.In this review,we discuss the structure characterization of dehydrins,and systematically summarizes recent advances in our understanding of the functions and mechanisms in multiple biological pathways as well as expression regulation,which will help us to further understand the biological function of the dehydrin gene family in normal plant growth and development and interactions with environmental factors.
