摘要
以pAHC20(含Bar基因)和pWRG1515(含GUS基因和潮霉素抗性基因)以及含Bar基因和雪莲凝集素(GNA)基因的pCAMBIA3300 RG为供体DNA,选用水稻品系87203、上农香糯及鄂宜105的成熟胚诱导出的愈伤组织及微不定芽为受体材料,分别采用基因枪和根癌农杆菌(LBA4404,含pAM404)导入法进行基因转化;经抗性筛选、GUS检测和PCR分析。结果表明,外源基因已通过基因枪法导入水稻鄂宜105,并获得再生植株;
Using pAHC20 (containing Bar gene), pWRG1515 (containing GUS gene and hygromycin phosphotransferase gene), and pCAMBIA3300 RG with Bar gene and snowdrop lectin (GNA) gene as donor DNA, the micro-adventitious shoots and the calli induced from mature embryos of Oryza sativa 87203. Eyil05. Shangnong aromatic glutinous rice as recipients were transformed with particle bombardment and Agrobacterium tumefaciens strain LBA4404 containing PAM404, respectively. After chosen with phosphinothricin and antibiotic, GUS detection and PCR analysis, The results showed that the foreign genes had been transformed microprojectile-mediated to Oryza sativa Eyil05, the regeneration plants were obtained, and, 5 transgenic calli of Oryza sativa Eyil05 were obtained with Agrobacterium-mediated transformation.
