摘要
非生物胁迫是一种广泛存在的环境胁迫形式,会严重降低作物产量.植物激素脱落酸(ABA)在应对重金属、干旱、热、高盐、低温和辐射等胁迫的耐受过程中起着重要作用.对ABA信号转导、ABA生物合成途径以及应激耐受转录因子相关的各种应激调节的研究进展进行了综述.
Abstract
Abiotic stress is a widespread form of environmental stress that can severely reduce crop yields.Plant hormone abscisic acid (ABA) plays an important role in the tolerance process fo,r coping with heavy metals,drought,heat,high salt,low temperature and radiation stress.The research progress on ABA signal transduction,ABA biosynthetic pathway and the regulation of stress-tolerance transcription factor related to various kinds of stress were reviewed.
