摘要:

DREB/CBF转录因子是植物AP2/ERF转录因子超家族的一个亚家族,具有AP2保守结构域,能特异性结合植物抗逆基因启动子区域DRE/CRT顺式作用元件。目前,越来越多研究表明,DREB/CBF转录因子参与调控植物响应干旱、盐、冷、热以及其他逆境胁迫的应答反应,是植物抗逆的关键调节因子。综述了近年来国内外DREB转录因子的研究进展,从DREB转录因子的结构、分类、家族及在非生物逆境胁迫中的功能等方面进行了总结,并结合当前研究的瓶颈,讨论了研究植物DREB/CBF转录因子的意义及存在的问题,并提出了今后的突破方向,以期为筛选优质抗逆植物资源,培育抗逆农林草新品种提供理论依据和指导。

Abstract:

Dehydration responsive element binding(DREB)/CBF is a subfamily of the AP2/ERF(APETALA2/ethylene-responsive factor)superfamily in plant,having AP2 conserved domain and binding specifically to the dehydration response element/C-repeat(DRE/CRT)cis-elements(also known as the DNA sequence motif G/ACCGAC)found in the promoter region of stress resistance genes. Recent studies demonstrate that DREB transcription factors are involved in plant responses to drought,salt,cold,heat and other abiotic stresses,and is a key regulator in plant stress resistance. In this paper,recent progress in DREB is reviewed and several key aspects including structure,classification,family and function in abiotic stress are summarized. Combining the current bottlenecks of studying DREB transcription factors in plants,the prospects and issues in this field are also discussed. Finally,the breakthrough directions for future works are emphasized,aiming to provide a theoretical basis and guidance in screening high-quality plant resources and breeding novel varieties of crops,forests and grasses.
