Abstract

Abstract: Plants often encounter cold stress，which influences the growth and geographical distribution，and decreases yield and quality of plants. bHLH（basic helix⁃loop⁃helix）family is the second largest transcription factor family in plant，which plays an important role in regulation of tolerance to cold stress.This paper elaborated the structure and the application of MYC（avian myelocytoma virus）⁃like bHLH transcription factor ICE［inducer of CBF（C⁃repeat binding factor） expression］ and other bHLH transcription factors in plant cold tolerance genetic engineering，so as to provide some references for the utilization of bHLH transcription factors in cold tolerance genetic improvement and breeding.

Key words: Plant, bHLH transcription factor, Cold tolerance, Genetic engineering

摘要： 植物在生长发育过程中经常遭遇低温胁迫，影响其生长发育、地理分布，降低产量、品质。bHLH（Basic helix⁃loop⁃helix）是植物中第二大转录因子家族，在植物抵御低温胁迫反应中具有重要的调控作用。阐述了植物bHLH转录因子的基本结构，综述了类似MYC（Avian myelocytoma virus）的bHLH转录因子ICE［Inducer of CBF（C⁃repeat binding factor）expression］和其他bHLH转录因子在植物耐冷基因工程中的应用进展，以期为bHLH转录因子在植物耐冷遗传改良、育种中的应用提供参考。
