【摘要】 干旱是影响植物生长的重要环境因素之一。植物在干旱胁迫下的响应策略一直是抗旱生理的研究热点。本研究综述了干旱胁迫下植物抗旱基因转录调控、渗透调节、活性氧清除、保护蛋白以及形态结构等方面的响应机制,并对未来植物抗旱研究提出了几点建议:结合转录组学、蛋白质组学等手段挖掘机理;加强干旱与其他环境因子复合胁迫效应对植物生长发育影响的研究。更多还原

【Abstract】 Drought is one of the most important factors affecting plant growth.Strategies of plant droughtresponse have always been a hot spot in drought tolerance physiology research.This paper reviewed the plantresponse mechanism under drought stress involving transcriptional regulation of drought resistant gene,osmotic adjustment,reactive oxygen species scavenging,protect enzymes and morphological structures.Someadvices for further studies on plant drought tolerance were provided,combining the transcriptomics andproteomics methods to investigate the mechanism of plant drought resistance,and strengthen the research onthe effect of the complex stress of drought and other environmental factors on plant growth and development.更多还原
