- 摘要:
- 采用花粉管通道法,将外源基因lkt50向大豆品种东农48和品系东农96-02导入。通过卡那霉素筛选,从所获得的种子苗中初选转化植株,进一步进行PCR、Southern blot及RT-PCR分子生物学检测。结果表明:在14株卡那霉素抗性材料中利用nptII基因的特异性引物有7株PCR阳性,利用lkt-50基因特异性引物有2株PCR阳性,并且2株Southern blot及RT-PCR检测均呈现阳性,因此认为花粉管通道法可以用于大豆的转基因研究和应用。
- Abstract:
- lkt50 gene was introduced into soybean cultivar Dongnong 48 and strain Dongnong 96-02 via pollen tube pathway.The transformed plants were primary screened from seedling by spraying kanamycin,and further the transformed plants was determined by molecular biological methods including PCR,Southern blot and RT-PCR.The results indicated that the identification of 14 Km resistant plants was determined by PCR with the use of the primers of nptII and lkt50,and seven and two plants were found to be positive respectively.Furthermore,the detections by Southern blot and RT-PCR revealed that the two plants were found to be positive.The pollen tube pathway is an effective,feasible method for soybean transgene.
