农杆菌介导CBL基因对菊花品种‘C008’的转化
发布时间:2018-09-07 07:25
【摘要】:以菊花品种‘C008’无菌苗叶片作为外植体,在建立了菊花高效再生体系的基础上,通过农杆菌介导法将CBL基因导入菊花品种‘C008’中。试验共获得抗性植株41株,PCR检测表明,阳性植株为5株,证明CBL基因已转化到菊花‘C008’的基因组DNA中,转化率为12.2%。遗传转化过程中,预培养2d后,将OD_(600)=0.5~0.6的农杆菌稀释50倍后侵染叶片8min,再共培养2d、延迟筛选2d,有利于获得较高的转化率。
[Abstract]:The leaves of aseptic seedling of chrysanthemum were used as explants. On the basis of establishing the efficient regeneration system of chrysanthemum, the CBL gene was introduced into chrysanthemum variety C008'by Agrobacterium tumefaciens. A total of 41 resistant plants were obtained. The results showed that there were 5 positive plants, which indicated that the CBL gene had been transformed into the genomic DNA of chrysanthemum C008', and the transformation rate was 12.2. In the process of genetic transformation, after 2 days of pre-culture, 50 times of Agrobacterium tumefaciens (OD_ _ (600) was diluted 50 times, then infected with leaves for 8 min, and then co-cultured for 2 days, then delayed screening for 2 days, which was beneficial to obtain higher conversion rate.
