It plays an important role in the regulation responses of plants to abiotic stress. To explore the abiotic stress tolerance role of DREB(ThDREB) from Tamarix hispida, the recombinant plasmid(named as pYES2-ThDREB) was constructed by inserting the ThDREB gene into the yeast expression vector pYES2. The plasmid pYES2-ThDREB was transformed into the yeast Saccharomyces cerevisiae, and the yeast transformed with empty pYES2 was used as the control. The pYES2-ThDREB and pYES2 recombinant yeast were treated with sorbitol, H2O2, CdCl2, NaCl, Na2CO3, MgCl2, and -20℃, respectively. The pYES2-ThDREB recombinant yeast was tolerant to all above abiotic treatments, suggesting that ThDREB maybe an important stress-regulating genes in T.hispida. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2017.01.009
