摘要: |
基于植物的抗性基因具有保守序列,根据已克隆基因的保守序列设计探针,利用菌落杂交的方法,对东乡野生稻大片段基因组文库进行筛选,得到两个候选克隆。序列比对发现其中含有NB-ARC的保守序列,可用于后续转基因鉴定。 |

Abstract: |
The resistant gene of plants has conservative sequence. Probes were designed in terms of the sequences of known resistance gene. With the colony hybridization method, the genomic library of Dongxiang wild rice was screened and two candidate clones were obtained. The sequences were analyzed with the blast program to the GenBank database and a conservative NB-ARC domain was found in both of the sequences. The clones would be transferred into rice for a further analysis. |
Keywords: NBS-LRR resistance gene colony hybridization genomic library |
