摘要: 在克隆获得磷高效相关转录因子基因GmPTF1的基础上,构建基因的超表达载体pGN-GmPTF1和无标记(Marker-free)表达载体pX6-GmPTF1;利用农杆菌介导子叶节与花粉管通道转化技术,将表达载体pGN-GmPTF1和pX6-GmPTF1分别转入冀豆12、冀豆16和五星1号大豆品种。转化后的大豆植株经PCR检测,有11株转化植株可扩增出目的条带,其中5株转有pGN-GmPTF1载体和6株转有pX6-GmPTF1载体,表明GmPTF1转录因子基因已初步整合至大豆基因组中。

Abstract: The over-expression vector pGN-GmPTF1and marker-free expression vector pX6-GmPTF1were constructed in this study base on the cloning and identification of GmPTF1,a soybean high phosphorus-efficiency transcription factor gene,and the vectors were introduced into different soybean varieties(Ji-dou 12, Ji-dou 16,Wu-xing 1) by Agrobacterium-mediated cotyledonary-node and pollen tube pathway transformation methods. PCR analysis results of transformation plants showed that the GmPTF1was successfully incorporated into the soybean genome. Total five PCR positive plants of vector pGN-GmPTF1and six PCR positive plants of vector pX6-GmPTF1were obtained from T0generation, respectively.
