As sessile organisms, plants are inevitably threatened by various abiotic stresses. Abiotic stresses seriously affect plant growth and development and crop yield. Plants have evolved complex regulatory networks to resist stresses that occur during their life cycle. The plant hormone abscisic acid (ABA) is accumulated under osmotic stress conditions such as drought, salt, and others. The ABA signaling pathway plays a key role in plant response to abiotic stresses, in which ABA-responsive element binding factors (ABFs) play a crucial role in the whole process. ABFs are a class of basic leucine zipper proteins (bZIPs) that specifically recognize ABA response elements and belong to the a subfamily of the bZIP family. The discoveries of ABFs-mediated tolerance to multiple abiotic stresses, including salinity, drought, cold, and heat stress are highlighted and discussed in this review. The aim of this review is to further analyze the mechanisms of abiotic stress regulation mediated by ABFs and to lay the foundation for breeding superior stress-resistant crop varieties.
作为固着生物，植物不可避免地受到各种非生物胁迫的威胁。非生物胁迫严重影响植物的生长发育和作物产量。植物已经进化出复杂的调控网络来抵御其生命周期中出现的胁迫。植物激素脱落酸（ABA）在干旱、盐胁迫等渗透胁迫条件下积累。ABA信号通路在植物对非生物胁迫的响应中起关键作用，其中ABA响应元件结合因子（ABFs）在整个过程中起至关重要的作用。ABFs是一类能够特异性识别ABA响应元件的碱性亮氨酸拉链蛋白（bZIPs），属于bZIP家族的a亚家族。本综述重点介绍并讨论了ABFs介导的对包括盐胁迫、干旱、寒冷和热胁迫在内的多种非生物胁迫的耐受性研究进展。本综述的目的是进一步分析ABFs介导的非生物胁迫调控机制，为培育优良抗逆作物品种奠定基础。
