摘要: 用根癌农杆菌(Agrobacterium tumefaciens )和基因枪两种方法,以桃(Prunus persica L. Batsch)幼胚子叶为受体,转化桃ACC氧化酶(ACO)反义基因片段,经筛选培养获得了卡那霉素抗性芽。微芽嫁接培养抗性芽部分可成株。PCR、Southern 杂交和GUS基因表达等分子检测,初步表明外源反义ACO基因已经整合到桃基因组中。

Abstract: Genetic transformation of peach immature cotyledons with its ACO antisense gene was studied by using particle bombardment method through Agrobacterium tumefaciens. Kanr shoots and Kanr plantlet were obtained. The plantet with ACO antisenes gene through Agrobacterium tumefaciens was obtained by micrografting technique and survived for nearly one month. The results of the PCR, PCR-southern, genomes southern hybridization analysis and GUS color reaction of some Kanr materials showed in some degree that the peach ACO antisens gene was integrated into peach genomes.
