摘要: 选黑田五寸胡萝卜栽培种,通过农杆菌介导的转化方法,获得转基因植株。结果表明:抗性愈伤和芽分化用不同浓度Kan筛选,Kan抗性芽的分化频率可达52%,Carb 500 mg/L能够完全抑制农杆菌的生长并能促进芽的分化;适当浓度的Cef对根形成有一定促进作用。转基因植株炼苗,采用塑料布覆盖并逐渐打开通风口通风的方法,抗性植株长势好,抗性强,成活率可以提高35%。低温春化,大棚和陆地相比,死亡率降低了49.5%。对7个株系T1植株的PCR分析,得出其中两株系接近1:1,另两株系为1:3。

Abstract: Seeds of carrots were selected for transformation via Agrobacterium to obtain transgenic plants.The results showed that frequency of the resistant callus and shoot regeneration in different concentration of Kanamycin(Kan) reached 52%.Carbenicillin(Carb) 500 mg/L completely inhibited the growth of Agrobacterium and promoted the growth of the resistant shoots.Moderate concentration of Cefotamine(Cef) could promote the growth of root.The resistance of plants covered with plastic membrane and gradually uncovered grew well and the survival rate enhanced 35%.Compared plants in the fields with those in the greenhouse,the death rate of carrot seedlings in the greenhouse reduced 49.5% in low temperature vernalization.PCR analysis for 7 transgenic plants in T-1 generation showed two lines of them were close to 1:1 and other two lines almost close to 1:3.

Key words: Carrots, Transgenic transformation, Vernalization, Agrobacterium mediated
