摘要/Abstract

摘要： 碱性螺旋—环—螺旋(basic helix-loop-helix,bHLH)蛋白属于转录因子超家族,在真核生物中广泛分布。目前,大部分bHLH转录因子功能在动物中已明确,但在植物中的研究相对滞后。bHLH转录因子作为植物体内第二大类转录因子,其在植物的生长发育、生理代谢及逆境应答等过程中起着重要的作用,它主要通过特定的氨基酸与靶基因的相互作用,进而调节相关基因的表达。为进一步了解bHLH转录因子在植物体内的功能和特点,现对其结构特点、分类及生物学功能进行阐述,主要侧重于其在非生物胁迫下的最新研究进行综述。该综述为深入理解bHLH转录因子在逆境胁迫下的分子作用机制提供理论依据。

Abstract: Basic helix-loop-helix (bHLH) proteins which belong to the superfamily of transcription factors are widely distributed in eukaryotes. At present, most of the functions of bHLH transcription factors have been identified in animals, however, it's study in plants is relatively limited. As the second major transcription factors in plants, based on their interactions between specific amino acids and the target genes, bHLH transcription factors play important roles in plant growth and development, physiological metabolism and stress response, and then regulate the expression of associated genes. In order to further understand the information on function and characteristics of bHLH transcription factors in plants, we reviewed their structural features, classification and biological functions, with focus on the most recently reported investigations on their response to abiotic stress. Our review may provide a theoretical basis for further understanding the molecular mechanisms underlying the actions of plant bHLH transcription factors in response to stress.

Key words: bHLH, drought resistance, salinity resistance, cold resistance
