DREBs响应植物非生物逆境胁迫研究进展
Research Progress in Response of DREBs to Abiotic Stress in Plant
摘要
Abstract
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.关键词
