摘  要:
用PCR方法从拟南芥和荠菜中分别克隆了DREB1A基因。序列分析发现从拟南芥中克隆的AtDREB1A基因与已发表的AtDREB1A基因序列(DQ372533)的同源性为99.69%,首次从荠菜中克隆的CbDREB1A基因序列(EF156749)与DQ372533的同源性为99.54%。利用这两个基因分别构建了两个诱导表达载体(prd29A/AtDREB1A,prd29A/CbDREB1A)和两个组成型表达载体(pCaMV35S/AtDREB1A,pCaMV35S/CbDREB1A),以便进一步开展植物抗旱基因工程研究。

摘  要:
The AtDREB1A and CbDREB1A genes were isolated from Arabidopsis thaliana and Capsella bursa-pastoris respectively by the method of PCR.Sequencing analysis of AtDREB1A indicated that the cloned fragment showed 99.69% identity to the published sequence(DQ372533).The sequence of firstly cloned CbDREB1A gene(EF156749)shared 99.54% identity with that of DQ372533.By using of AtDREB1A and CbDREB1A genes,two induced expression vectors(prd29A/AtDREB1A,prd29A/CbDREB1A)and two constitutive expression vectors(pCaMV35S/AtDREB1 A,pCaMV35S/CbDREB1A)in plant were constructed.The obtained expression vectors can be applied on plants genetic engineering for drought-tolerance improvement.
