- 摘要:
- 采用PCR 方法克隆大豆光周期GmGBP1 基因启动子,构建含有GmGBP1 启动子驱动报告基因GUS 的融合性表达载体pBI121-pGmGBP1: : GUS,通过花序浸泡法,转化野生型拟南芥获得pBI121-pGmGBP1: : GUS 转基因植株,对T3代转基因拟南芥进行GUS 染色,研究了GmGBP1 启动子受激素和外源环境诱导的表达规律。结果表明: 大豆GmGBP1启动子受水杨酸( SA) 和干旱( PEG) 以及高温等外源环境的诱导,与生物信息学预测GmGBP1 启动子序列存在的逆境胁迫响应元件的结果相一致。
- Abstract:
- The expression pattern of the GmGBP1 promoter under hormone and environment were obtained. The GmGBP1 promoterwas cloned by PCR and the fusion expression vector was constructed,including the GmGBP1 promoter and the reportergene GUS. The fusion expression vector was used to infect Arabidopsis thaliana,and T3 generation of transgenic Arabidopsiswas obtained,then the GUS staining was used to research the expression pattern of the GmGBP1 promoter in Arabidopsis thaliana.The results showed that the expression of the GmGBP1 promoter was regulated by GA,SA,drought and high temperature,consistent with the predictions of GmGBP1 promoter element by bioinformatics analysis. Our experiment provide theoreticalbasis for the cultivation of resistant crops in the future.
