摘  要:
玉米是拥有转基因转化体数量最多的作物,多样的转化体增加了玉米中转基因成分筛查的难度。为了建立玉米中转基因成分的快速筛查方法,利用Taqman探针实时荧光PCR方法,通过对玉米样品中CaMV35S启动子(P-35S)和NOS终止子(T-NOS)2个元件组合的检测,完成对现有玉米转化体的筛查。建立的Taqman探针实时荧光PCR方法灵敏度可达到0.1%,检测时间较普通PCR方法缩短1h以上。同时提出了转基因玉米转化体鉴定路线图。该筛查方法可对玉米中的转基因成分进行快速、高灵敏度的筛查。

摘  要:
Maize is the crop of having the largest amount of genetically modified(GM)events.Varied GM events make it difficult to screen GM ingredients in maize.In order to establish a rapid screening method for GM maize,the combination of CaMV35Spromoter(P-35S)and NOS terminator(T-NOS)was used to screen all the commercial GM maize events based on Taqman real-time fluorescence PCR.The sensitivity of the method was of 0.1%.The time cost in Taqman real-time fluorescence PCR was one hour less than conventional PCR.In addition,the identification pathway of genetically modified maize event was presented in this article.In conclusion,this Taqman real-time fluorescence PCR method can be used for rapid and sensitive screening of GM maize events.
