| 摘 要： | 以大豆"黑农37"胚尖为外植体,利用农杆菌介导法将抗除草剂基因EPSPS转入大豆,并对转化各培养阶段6-苄氨基腺嘌呤(6-BA)浓度进行了优化。结果表明:在预培养和共培养培养基中加入较高浓度6-BA有利于抗性芽的诱导;1mg/L6-BA和0.2mg/L吲哚丁酸(IBA)配合使用有利于抗性芽的伸长且提高了抗性芽的再生率;将抗性芽添加在1mg/L IBA的培养基中培养7d后转入不加任何激素的培养基中生根快且移栽后成活率高。PCR结果初步证明将EPSPS基因转入到大豆中。 |

| Abstract: | The herbicide resistant gene(EPSPS)was transferred into soybean embryonic tip using the Agrobacterium-mediated transformation,and the transformation system was optimized.The results showed that higher 6-BA concentrations in the pre-culture and co-culture medium could induce resistant shoots.The results also indicated that 1mg/L 6-BA and 0.2mg/L IBA could improve regeneration rate of the resistant shoots and elongate resistant shoots length.The shoots rooted quickly when cultured in medium with 1mg/L IBA for 7 days and then transferred to the medium without any hormones.PCR results indicated that the EPSPS gene had been transferred into soybean. |
