DREBs响应植物非生物逆境胁迫研究进展OACSCD
Research Progress in Response of DREBs to Abiotic Stress in Plant
寒冷、干旱和高盐等非生物胁迫作为常见的不利环境条件,严重影响全球植物生长和生产力.干旱应答元件结合蛋白(dehydration responsive element binding protein,DREB)是植物重要转录因子之一,其家族成员均含有一个 57-70 个氨基酸残基的保守AP2 结构域.DREB通过与胁迫诱导基因启动子区中的脱水反应元件/C-重复(dehydration responsive element/C-repeat,DRE/CRT)顺式作用元件相互作用,调节下游各种应激基因的表达,赋予植物应激耐受性.本文从DREB家族结构特点和分类出发,结合最新研究进展,阐述其在非生物胁迫过程中的作用机制,旨在更加深入地了解DERB类转录因子在非生物胁迫响应过程中的分子调控网络,以期为未来利用基因工程手段提高植物抗逆性方面提供参考.
Abiotic stresses such as cold,drought and high salinity seriously affect the global plant growth and productivity.Dehydration Responsive Element-Binding(DREB)is one of the important transcription factors in plants,and its family members all contain a conservative AP2 domain with 57-70 amino acid residues.DREBs regulate the expressions of various stress genes downstream and endows plants with stress tolerance by binding to dehydration responsive element/C-repeat(DRE/CRT)cis-acting elements in the promoter region of stress-induced genes.This article summarizes the current progresses on the structural characteristics,classification of DREB family,mainly focusing on their functions and molecular mechanisms in response to abiotic stress,aiming to have a deeper understanding of the molecular regulatory network of DREB transcription factors in the stress response process,and to provide a reference for improving plant stress tolerance through genetic engineering in the future.
