摘要
利用改进的冻融法和电击法成功地将带有编码DREB转录因子GmDREB基因的prdGm-200双元载体分别导入根癌农杆菌EHA101、EHA105和LBA4404菌株中,同时探讨了影响冻融法和电击法转化效率的因素。结果表明:农杆菌细胞OD600约为0.6时冻融法和电击法的转化效率均较高。在利用冻融法转化农杆菌时,新制备的感受态细胞有利于提高转化效率。在进行电击法转化农杆菌时,电场强度和脉冲时间都对农杆菌的转化效率有影响。
The binary vector prdGM-200 with GmDREB gene coding for translation factor DREB was transformed into Agrobacterium tumefaciens strains EHA101, EHA105 and LBA4404 by using freeze-thaw method and electmporation respectively. The factors influencing transformation efficiencies through freezethaw and electmporation methods were studied. The results showed that higher transformation efficiency was observed when the value of OD600 reached 0.6. The new competent cell could increase transformation efficiency using freeze-thaw method. While transformation efficiency was influenced by electric field intensity and pulse time when electmporation method was applied.
