| 摘 要： | 设计了含有不同2,4-D浓度的6种培养基用于玉米胚性愈伤组织的继代培养,对影响转化效率的侵染条件进行了研究,根据转化后所得的抗性愈伤组织数目及其分化率的评估结果表明,选用N6为基本培养基,添加1mg/L 2,4-D时,胚性愈伤组织继代长势较好,且在真空渗透的情况下,侵染5min,抗性愈伤组织数最多。经初步的PCR鉴定,利用优化的玉米遗传转化体系得到了转基因玉米植株。

| Abstract: | Six culture medias with different concentration of 2,4-D were designed and used for subculture of embryogenic callus of maize to investigate infection conditions that affect the efficiency of genetic transformation and to evaluate the number of antibiotic resistant callus and differentiation ratio after transformation.The results showed that N6 media supplemented with 2,4-D 1mg/L was suitable for subculture of embryogenic callus,If a vacuum pen-etration treatment and infection for 5min were also used,the mo... |
