Normal phenotype sugarbeet plants transformed with Agrobacterium rhizogenes were produced using direct regeneration from explants without hairy root phase. Kanamycin resistant plants and Ri-roots carrying the genes of neomycin phosphotransferase II and b-glucuronidase have been obtained. Integration of transgenes into sugarbeet genome was confirmed with GUS-assay and PCR using primers for the introduced genes.
利用外植体直接再生法,在不经过毛状根阶段的情况下,培育出了用发根农杆菌转化的具有正常表型的甜菜植株。已获得了携带新霉素磷酸转移酶II基因和β-葡萄糖醛酸酶基因的卡那霉素抗性植株和发根。通过GUS检测和使用导入基因引物的PCR,证实了转基因已整合到甜菜基因组中。
