| 摘 要： | 以烟草叶片为试材,用转入植物表达载体pBI121的根癌农杆菌EHA105进行遗传转化。通过分析菌液不同浓度、侵染时间、乙酰丁香酮浓度及共培养时间对GUS基因表达的影响,研究其瞬时表达的最佳条件。结果显示:用OD600值为0.6的农杆菌侵染6min,在培养基中添加120μmol.L-1的乙酰丁香酮,共培养2d,能够得到高效的GUS基因瞬时表达。

| Abstract: | An experiment was conducted to investigate the transient expression mediated by Agrobacterium using the leaves of tobacco (Nicotiana tabacum L.) as explants and the Agrobacterium tumefaciens EHAl05 containing the plant expression vector pBI121 for genetic transformation.Effects of A.tumefaciens concentration,infection time,acetosyringone concentration,and co-culture length on the transient expression of GUS gene were analysed to determine the optimal transformation condition.A higher transient expression le... |
