Abstract
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.
植物作为无根生物，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生长发育和作物产量。植物已经进化出复杂的调节网络来抵抗在其生命周期中发生的压力。植物激素脱落酸（ABA）是在干旱、盐等渗透胁迫条件下积累的。ABA信号通路在植物对非生物胁迫的响应中起着关键作用，其中ABA响应元件结合因子（ABA-responsive element binding factors, ABFs）在整个过程中起着至关重要的作用。ABFs是一类特异性识别ABA应答元件的碱性亮氨酸拉链蛋白（bZIP），属于bZIP家族的a亚家族。这篇综述强调并讨论了abfs介导的对多种非生物胁迫的耐受性，包括盐度、干旱、寒冷和热胁迫。本文旨在进一步分析ABFs介导的非生物胁迫调节机制，为培育抗逆性优良作物品种奠定基础。
期刊介绍：
Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
