摘　　要：DREB是植物中重要的转录因子,调控一系列非生物胁迫相关基因的表达,增强植物抵抗环境胁迫的能力。同时,当植物受到逆境胁迫时,植物体内的酶和激素都会发生变化,从而影响一系列的生理活动或生化变化来产生抵御胁迫的适应能力。近些年来,研究者们发现DREB与植物激素之间关系密切,从植物激素角度入手研究DREB的功能逐渐成为热点。就逆境胁迫下DREB转录因子与激素之间的相互作用进行阐述。The dehydration responsive element binding proteins（DREB）are important transcription factors that induce a set of abiotic stress-related genes and impart stress endurance to plants.At the same time,when the plants undergo exposure to various stresses in their natural environment,enzymes and hormones in plants will change,affecting a range of physiological or biochemical changes to generate the adaptive capacity to withstand stress.In recent years,researchers have increasingly found that the close relationship between DREB and plant hormones,from where we could study the function of DREB.The recent progresses on research of interaction between DREBs and plant hormones under stress were reviewed.
