摘要
干旱严重影响植物的生长发育乃至产量、品质。抗旱育种是保障植物生产的重要措施,利用基因工程技术提高植物抗旱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,在植物抵御干旱胁迫反应中具有重要的调控作用。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、玉米、大豆等作物抗旱基因工程中应用的研究进展,为MYB转录因子的利用及植物抗旱遗传改良及育种提供参考。
Drought seriously affects the growth,yield and quality of plant.Drought tolerance breeding is an important measure to ensure plant production.It is an effective way to improve plant drought tolerance through genetic engineering technology compared with the conventional breeding methods.MYB transcription factors are one of the largest transcription factor families in plant,which play an important role in regulation on plant tolerance to drought stress.This paper systematically and comprehensively elaborated the application of MYB transcription factors in plants(Arabidopsis thaliana,Nicotiana tabacum,Oryza sativa,Zea mays and Glycine max,etc)drought tolerance genetic engineering,so as to provide some references for the utilization of MYB transcription factors and drought tolerance genetic improvement and breeding.
