Summary We characterized the expression of genes that correspond to a cDNA clone, RD29, which is induced by desiccation, cold and high-salt conditions in Arabidopsis thaliana. Northern analysis of desiccation-induced expression revealed a two-step induction process. Early induction occurs within 20 min and secondary induction occurs 3 h after the start of desiccation. Exogenous abscisic acid (ABA) induces RD29 mRNA within 3 h. Two genes corresponding to RD29, rd29A and rd29B, are located in tandem in an 8 kb region of the Arabidopsis genome and encode hydrophilic proteins. Desiccation induces rd29A mRNA with two-step kinetics, while rd29B is induced only 3 h after the start of desiccation. The expression of both genes is stimulated about 3 h after application of ABA. It appears that rd29A has at least two cis-acting elements, one involved in the ABA-associated response to desiccation and the other induced by changes in osmotic potential. The -glucuronidase (GUS) reporter gene driven by the rd29A promoter was induced at significant levels by desiccation, cold, high-salt conditions and ABA in both transgenic Arabidopsis and tobacco. Histochemical analysis of GUS activity revealed that the rd29A promoter functions in almost all the organs and tissues of vegetative plants during water deficiency. 相似文献

Overexpression of two chrysanthemum DgDREB1 group genes causing delayed flowering or dwarfism in Arabidopsis 总被引:1,自引:0,他引:1

We isolated 13 DREB1 (dehydration responsive element binding factor 1) genes from chrysanthemum and further divided them into three groups, DgDREB1A, DgDREB1B and DgDREB1C, based on the phylogenetic analysis. Each group showed their unique expression patterns under cold, dehydration and salt stress conditions. Arabidopsis plants overexpressing DgDREB1A (1A plants) exhibited significantly stronger tolerance to freezing and drought than those overexpressing DgDREB1B (1B plants) and the control plants. In addition, 1A plants showed delayed flowering, but not dwarfism; while 1B plants showed dwarfism, but not delayed flowering. In 1A plants, the expression of three stress-related DREB1-downstream genes, COR47, COR15A, and RD29A, was strongly induced while the expression of CO and FT, two photoperiod responsive flowering-time genes, was inhibited. In 1B plants, the expression of GA2ox7, a GA-deactivation enzyme gene, was dramatically enhanced. The results above strongly suggest that members from different DgDREB1 groups may have distinct effects on plant development: DgDREB1A may be involved in photoperiod-related flowering-time determination and DgDREB1B in GA-mediated plant development. 相似文献
