摘要
脱落酸(abscisic acid,ABA)是能够引起植物芽休眠、叶子脱落和抑制细胞生长等生理作用的一种植物激素,也是能够提高植物抗逆能力的一种“非生物应激激素”。ABA是植物响应非生物胁迫的重要信号分子,在应答植物非生物胁迫如干旱、高盐、低温等中具有重要的生物功能。综述了近10年关于外源ABA对植物抗逆响应机理的研究,系统地从种子萌发、幼苗生理生化、分子调控等层面开展论述,旨在为ABA在植物非生物胁迫中抗逆功能的深入研究提供参考,并为非生物胁迫下的农作物育种和生产提供理论依据。
As a kind of plant hormone,abscisic acid (ABA),causing plant bud dormancy,leaf detachment and cell growth inhibition,could improve the plants’ resistance to abiotic stress as an “abiotic stress hormone”.ABA is an important signal molecule for plant responding to abiotic stress and has important biological functions in resistance to abiotic stresses such as drought,high salt and low temperature.In this paper,the studies on mechanisms of ABA responding to abiotic stress in recent 10 years were reviewed,and systematically elucidated from seed germination,seedling physiology and biochemistry,and gene regulation levels,which will greatly facilitate to further study the function of ABA in plant abiotic stress resistance,and provide theoretical basis for crop breeding and production under abiotic stress.
