通过基因枪转化法将外源抗虫基因导入 1个玉米 (ZeamaysL .)优良自交系。对受体愈伤的制备 ,抗性愈伤的筛选分化和转基因植株的移栽等方面的研究 ,采用一系列的措施 ,有效地降低了转化植株的畸形率 ,提高了转化植株的成活率 Exogenous insect-resistant genes were introduced into one maize (Zea mays L.) elite inbred line by the gene gun transformation method. The preparation of receptor callus, selection of resistant callus, transplanting of transgenic plants and so on, a series of measures were adopted to effectively reduce the rate of deformity of transformed plants and increase the survival rate of transformed plants
