- 摘要:
- 以 3 个大豆品种的体细胞胚为受体,以 PSY 为目的基因 ,应用基因枪法对大豆进行了遗传转化 ,实验结果表明 :不同大豆基因型的体细胞胚对抗性选择标记(Hyg)的敏感性存在极显著差异;高渗处理的培养基加入 0. 4mol /L 甘露醇有利于 PSY 基因的导入;对已获得 10 株抗性再生苗,经 PCR 和 PCR- Southern 分析鉴定 ,有 4 株为阳性,初步证明外源基因 PSY 已整合到大豆的基因组中。
- Abstract:
- Using somatic embryogenesis of three varieties of soybean as acceptor , PSY gene were trans-formed into soybean via particle bombardment. The results showed:the sensitivity of somatic embryo ofsoybean with different genotypes to resistance selective marker(Hyg) is significantly different ;high os-motic pressure medium with 0. 4mol /L mannitol was beneficial for the transformation of target gene. 10resistant regenerated plants were obtained from the three varieties, 4 plants gave positive reaction in PCRand PCR- Southern analysis from the gene transferred plants ,indicating that PSY has been transferred intogenome of soybean.
