摘要: 利用前期构建的P450基因的RNAi植物表达载体侵染蓖麻受体材料,旨在获得转P450基因的阳性株。以蓖麻品种通蓖5号为试验材料,利用根癌农杆菌介导法转化蓖麻子叶节,研究影响子叶节遗传转化的若干因素。结果表明:子叶节对Kan较为敏感,适宜筛选质量浓度为250mg/L;外植体预培养2—3d,侵染用农杆菌菌液OD600=0.8,侵染时间10min,共培养3d,可获得较高的遗传转化效率。再生植株经PCR和Southern Blot检测,证明为转基因植株。

Abstract: In order to gain positive strains of transgenic using pre-built RNAi expression vector infection castor receptor material. In this study,several factors affecting transformation rate were studied by Agrobacterium mediated in Tong bi No. 5 castor. The results showed that : cotyledonary node of castor were rather sensitive to kanamycin, and corresponding concentration was 250 mg/L. The pre-cuhure time of 2 - 3 days, the bacterial concentration of OD600=0.8 was the best inoeulum density and 10 minutes was the best inoculation time,co-culture for 3 days were bene- ficial to improve transformation frequency. The PCR and Southern blot analysis proved that the target gene was suc- essfully integrated into the genome of castor.

Key words: Castor, Cotyledonary node, Genetic transformation
