摘要: 根据文献上发表的逆境诱导型启动子rd29A 序列设计并合成了一对引物, 通过PCR 的方法从拟南芥基因组中扩增到rd29A 的启动子序列。根据GenBank 中已发表的转录因子DREB1A基因的cDNA 序列设计并合成了一对引物, 通过RT-PCR 的方法从低温处理的拟南芥总RNA 中扩增出DREB1A 基因的全长cDNA 片段。以植物表达载体pBch 为基础, 构建了由rd29A 调控的DREB1A 基因的植物表达载体pBDR29A, 为利用DREB1A 基因改良植物抗逆性奠定了物质基础。

Abstract: According to the reported sequence of inducible expression promoter rd29A a pair of primer was designed and synthesized.Using the genomic DNA of Arabdopsis thaliana as templet, fragment of rd29A promoter was amplified through method of PCR.According to the cDNA sequence of transcription factor DREB1A gene in GenBank a pair of primer was designed and synthesized.Using the total RNA of low temperature treated Arabdopsis thaliana seedling as templet, the full length of cDNA of DREB1A gene was amplified through method of RT-PCR.The plant express vector pBch was digested and ligated with the DREB1A cDNA fragment and rd29A promoter fragment and got the DREB1A gene plant express vector pBDR29A regulated by inducible promoter.

Key words: inducible promoter, rd29A, transcription factor, DREB1A, construction of express vector
