Abstract

Abstract: Rice often encounters drought, high salt, low temperature, pathogen stress, which influences the growth and yield of rice.NAC transpription factors are the plant-specific and one of the largest families, which play an important role in regulation of plant growth and a variety of abiotic and biotic stresses response. This paper systematically and comprehensively elaborated the structure, classification and chromosomal location of NAC transpription factors, reviewed the application of NAC transpription factors in plant drought, salt, cold and disease resistance, so as to provide some references for the utilization of NAC transcription factors and stress tolerance genetic improvement and breeding.

Key words: rice, NAC transpription factors, drought tolerance, salt tolerance, cold tolerance, disease resistance, genetic engineering

摘要： 水稻经常遭遇干旱、高盐、低温、病原菌等逆境胁迫，影响其生长发育甚至产量。NAC转录因子是植物特有的、最大的转录因子家族之一，在水稻生长发育及抵御多种非生物及生物胁迫反应中具有重要的调控作用。本文阐述了水稻NAC转录因子的结构、分类及染色体定位，并阐述了NAC转录因子在水稻抗旱、耐盐、耐冷及抗病等抗逆基因工程中应用的研究进展，为NAC转录因子的利用及水稻抗逆遗传改良提供参考。
