摘　　要：[ Objective] The study is to generate pharmaceutical protein via plant transgenic technique. [Methed] Using the cotyledons with petiole as transformation receptor, the fusion gene of rapeseed oil-body gene and bFGF was introduced into the rapeseed （ Brassica campestris L. ） by Agrobacterium tumefaciens-mediated transformation; meanwhile regeneration conditions of rapeseed were also optimized, and the regenerated resistant plantlets were detected by PCR and Southern blot. [ Result] This fusion gene had been integrated into rapeseed genome successfully, and the optimized conditions of transformation and regeneration were as follows： explants pre-culture for 2 d, co-culture for 3 d, bacteria solution OD600 for 0.3 and infection time for 5 min. [ Conclusion] The results laid a solid foundation for extraction, isolation and purification of protein in transgenic plant seeds.1材料与方法1．1材料1．1．1供试材料。白菜型油菜苏州青，市售。1．1．2菌株及质粒。采用根癌农杆菌LBA4404，该菌株含有植物双元表达载体pCAMBIA1390，油菜油体基因与bFGF的融合基因已整合到该载体上，该融合基因由油菜油体基因启动子启动。植物基因组提取试剂盒购自北京百泰克生物技术有限公司，Southern检测试剂盒为DIG High Prime DNA Labeling and Detection Starter Kit I，购于Roche公司。
