摘要: 将可以诱发植物对病原菌抗性的甜椒hrap基因置于35S启动子的驱动下, 经农杆菌介导引入
番茄。再生植株经过含卡那霉素的培养基的选择, 后经PCR 检测和Southern杂交鉴定含有目标基因。Northern杂交检测其表达后, 初步的抗菌检验显示其提高了对青枯病原菌的抵抗力。

关键词: 番茄, 遗传转化

Abstract: Sweet pepper hrap gene under the control of CaMV 35S promoter has been transformed into tomato via Agrobacterium tumefaciens mediated procedure. Plantletswere regenerated onMSmedium with 3.0mg·L - 1 6-BA, 0.2 mg·L-1 IAA, and 50 mg·L-1 kanamycin1 The transgenic plants had been identified by
PCR procedure and Southern blot, and their exp ression was showed by Northern hybridization. A preliminary assay with leaf disc infected by tomato pathogen Ralstonia solanacea rum Smith showed that transgenic plants
had higher resistance to the pathogen than wild2type tomato.

Key words: Tomato, Genetic transformation
