转录因子DREB、ERF和NAC在介导植物响应生物和非生物胁迫中的作用

Roles of Transcription Factors DREB,ERF and NAC in Mediating Plant Responses to Biotic and Abiotic Stresses

生物和非生物胁迫是影响植物生长和造成农业减产的重要原因.近年来,已经鉴定了几个可以调控胁迫相关基因表达的转录因子.这些转录因子在控制植物生物系统转录重编程中起重要作用,能提高植物对生物和非生物胁迫的耐受能力.因此,识别和表征与植物胁迫反应有关的关键基因对增强转基因植物的胁迫耐受能力是必不可少的.本文介绍了DREB、ERF和NAC转录因子,重点介绍其在转基因植物增强对生物和非生物胁迫耐受性的潜力.

The adverse effects of biotic and abiotic stresses are major factors which affect plant growth and reduce agricultural yield.In recent years,several transcription factors had been identified that could regulate the expression of stress-related genes.These transcription factors played a crucial role in controlling transcriptional reprogramming in the development of plant biological systems,and also enhanced the biotic and abiotic tolerance of plants.Therefore,it is essential to identify and characterize the key genes involved in plant stress responses to enhance the stress tolerance of transgenic plants.DREB,ERF and NAC transcription factors have been introduced with emphasis on their potential to enhance the tolerance of transgenic plants to biotic and abiotic stresses in genetic engineering.
