摘要 分子和遗传研究表明,转录因子在响应非生物胁迫的基因表达调控中起着重要的作用,并且大部分转录因子在禾本科植物和拟南芥中是相同的。禾本科植物包括许多重要的农作物,对禾本科植物的转录因子进行研究,可增强重要农作物对非生物胁迫的耐受性。综述了禾本科植物响应非生物胁迫的转录调控网络,包括响应寒冷胁迫的DREB1/CBF调节子、响应脱水和高盐胁迫的DREB2调节子,ABA介导反应的ABRE及其伴侣元件、响应ABA的AREB/ABF调节子,响应脱水、高盐和寒冷胁迫的NAC调节子。 Molecular and genetic studies provided evidence that transcription factors play important roles in the regulation of gene expression in response to abiotic stresses and most transcription factors are common between grasses and Arabidopsis.The grasses include many agriculturally important plants,the studies on these transcription factors can be used to improve stress tolerance to abiotic stresses in various grasses.In this review,the transcriptional regulatory networks in response to abiotic stresses in grasses were described,including DREB1/CBF Regulon in response to cold stress,DREB2 regulons in response to dehydration and high salinity,ABRE and coupling elements for ABA-mediated responses,AREB/ABF regulon in response to ABA,NAC regulon for dehydration,high salinity,and cold stress.
