MYB转录因子在植物耐盐基因工程中的应用进展

Progress on application of MYB transcription factor in plant salt tolerance genetic engineering

盐胁迫是影响植物生长、发育及作物产量的重要环境因子。耐盐育种是保障农业生产的重要措施,利用基因工程技术提高植物耐盐性是优于传统育种的有效途径。MYB转录因子是植物中最大的转录因子家族之一,在包括盐胁迫在内的植物非生物胁迫调控中有重要作用。本文系统阐述了MYB转录因子的基本结构及其在拟南芥、烟草及水稻、大豆、番茄等植物耐盐基因工程中应用的研究进展,为MYB转录因子的利用及植物耐盐遗传改良及育种提供参考。

Salt stress is a major environmental factor that affects plant growth,development and crop yields.Salt tolerance breeding is an important measure to ensure agricultural production.It is an effective way to improve plant salt tolerance through genetic engineering technology compared with the conventional breeding methods.MYB family is one of the largest transcription factor families in plants,which plays an important role in regulation on plant tolerance to abiotic stresses including salt stress.This paper systematically and comprehensively elaborated the application of MYB transcription factors in salt tolerance genetic engineering of Arabidopsis thaliana,tobacco(Nicotiana tabacum),rice(Oryza sativa),soybean(Glycine max)and tomato(Solanum lycopersicum),etc,so as to provide some references for the utilization of MYB transcription factors and salt tolerance genetic improvement and breeding.
