摘要
bHLH(basic/helix-loop-helix)转录因子在真核生物的生长发育过程中起着重要的调控作用,它们组成了转录因子中的一个大家族。bHLH转录因子不仅普遍参与了植物的生长发育,包括毛状体的发生、光形态建成和光信号转导,而且在植物响应逆境胁迫和次生代谢方面也具有重要作用。对植物bHLH转录因子的结构特点及其生物学功能进行综述。
The basic/helix-loop-helix（bHLH） transcription factors play important roles in various developmental processes of eukaryotes.They constitute a superfamily of transcription factors that have been well characterized in mammalian systems,in which considerable structural,functional,and phylogenetic analyses have been performed.The family has been not only implicated in plant growth and developmental processes,including formation of trichome,photomorphogenesis and light signal transduction,but also involved in stress responses and secondary metabolism.The progress of the basic structure and biological function of plant bHLH transcription factors was reviewed.
