摘    要: 将含有魔芋AGPase反义基因的质粒pBAGP通过冻融法转化到根癌农杆菌(Agrobacterium tumefaciens)菌株LBA4404中,再采用叶盘法将其转化进番茄(Lycopersicon esculentum Mill.)栽培品种“合作908”中,获得含AGPase基因的番茄抗性植株。最后,经卡那抗性鉴定、NPTⅡ基因和AGPase基因PCR扩增和PCR-Southern杂交检测表明,反义AGPase基因成功整合到番茄基因组,为番茄改良品质育种奠定了材料基础。

关 键 词:腺苷二磷酸葡萄糖焦磷酸化酶  反义载体  遗传转化  番茄

Abstract:Carrying an Amorphophallus adenosine diphosphate glucose pyrophosphorylase (AGPase) anti-sense gene under the drive of CaMV35S promoter,the plasmid pBAGP was transferred into tomato (Lycopersicon esculentum Mill) cultivar “Hezuo908” via agrobacterium-mediated transformation. The results of anti-kanamycin test, PCR amplifications of AGPase gene and NPTⅡ gene and PCR-southern blotting proved that AGPase anti-sense gene was successfully integrated into genome of tomato, which provided a material basis for improving tomato breed.
Keywords:Adenosine diphosphate glucose pyrophosphorylase(AGPase)  anti-sense vector  genetic transformation  Lycopersicon esculentum
