DREB转录因子研究进展 总被引:9,自引:1,他引:8
DREB转录因子即干旱应答元件结合蛋白质,它能特异结合启动子中含有 DRE/CRT 顺式元件,激活许多逆境诱导基因的表达,增强植物对逆境的忍耐力。介绍DREB转录因子与DRE顺式作用元件的关系,DREB 转录因子与 DRE 元件的结合特异性,DREB 的结构特点和功能,DREB 转录因子的表达调控,DREB 转录因子的克隆及鉴定等方面的研究进展,简述 DREB 转录因子对调控逆境诱导基因的表达具有非常重要的作用,在提高植物综合抗逆性方面将有巨大的应用前景。同时,指出 DREB 转录因子在信号转导、作用机理及基因表达等方面的复杂性。

In plants, a cis-acting element, DRE/CRT, is involved in ABA-independent gene expression in response to dehydration and low-temperature stress. To understand signal transduction pathways from perception of the dehydration stress signal to gene expression, we characterized a gene family for DRE/CRT-binding proteins DREB2A and DREB2B in Arabidopsis thaliana. Northern analysis showed that both genes are induced by dehydration and high-salt stress. Organ-specific northern analysis with gene-specific probes showed that these genes are strongly induced in roots by high-salt stress and in stems and roots by dehydration stress. The DREB2A gene is located on chromosome 5, and DREB2B on chromosome 3. We screened an Arabidopsis genomic DNA library with cDNA fragments of DREB2A and DREB2B as probes, and isolated DNA fragments that contained 5-flanking regions of these genes. Sequence analysis showed that both genes are interrupted by a single intron at identical positions in their leader sequence. Several conserved sequences were found in the promoter regions of both genes. The -glucuronidase (GUS) reporter gene driven by the DREB2 promoters was induced by dehydration and high-salt stress in transgenic Arabidopsis plants. 相似文献

DREB1A是DREB转录因子的一员,它们都含有一段与DNA结合的保守区域,由58个氨基酸组成,称为EREBP/AP2结构域(EREBP/AP2 domain)。一个DREB转录因子可以调控多个与植物干旱、高盐及低温耐性有关的功能基因表达。从拟南芥中克隆了DREB1A转录因子基因,成功构建了DREB1A基因的原核表达载体,转化E.coliBL21(DE3),经1 mmol/L IPTG诱导表达获得了DREB1A蛋白,但以包涵体形式存在。为以后深入研究DREB转录因子与DRE顺式作用元件相互作用的具体机制奠定了基础。 相似文献
