摘要: 通过根癌农杆菌( Agrobacterium tumefaciens) 介导, 利用特异表达的phaseolin 基因
的启动子与人类野生型抗癌基因p 53 构建嵌合基因, 对􀀂 美味樱桃 番茄进行遗传转化, 获
得转化番茄再生植株。通过组织化学法、PCR 扩增及Southern 杂交检测, 证明人类野生型p 53基因已整合到转基因番茄植株的基因组。

关键词: 番茄, 人类野生型抗癌基因p 53, 遗传转化

Abstract: The strain GV3101 of Agrobacterium tumerf aciens harboring a plasmid carrying a human wild􀀁type tumor suppressor gene p 53 driven by the promoter of phaseolin was used to transform cv. Meiwei Cherry of tomato. Leaves of transgenic tomato plants were used for assaying the existence of foreign gene. Results of histochemical assay, PCR amplification and Southern blotting showed that the human wild􀀁type p 53 gene was integrated into the genome of transgenic tomato plants.

Key words: Tomato, Human wild􀀁, type p 53 gene, Genetic transformation
