| 7. | 2 . the potato transformation system that was mediated by agrobacterium fumefaciens ehalos . was established , the optimal callus - forming mediums and callus - differentiating medium were selected and found for potato transformation system . the rates of calli and shoot differentiation were respectively 100 % and more than 90 % for transgenic potato with si gene of infectious bronchitis virus 2建立了马铃薯农杆菌介导的遗传转化体系,确定了马铃薯最佳愈伤诱导培养基及最佳分化培养基,愈伤形成率达100 ,芽的分化率达90以上。 |
| 8. | The sequences of the structural protein genes and deduced a mino acid sequence of isolate lx4 were compared . by computer software , complete main structural genes sequence of ibv domestic strain and molecular characteristic genetic - variant analyses , and probably t cell and b cell epitopes of the main structural protein of infectious bronchitis virus were analyzed premently 通过计算机分析软件,对我国ibv地方流行毒株lx4的主要结构基因全序列、分子特征及遗传变异进行分析比较,并初步分析预测传染性支气管炎病毒主要结构蛋白上可能存在的t细胞和b细胞表位。 |
| 9. | In this paper , a field strain of infectious bronchitis virus was isolated from proventriculus tissue , morphological observation by electron - microscope and the biological characterizations of the virus were studied , pairs of specific primers are designed and synthesized in correspondence with them , according to the published sequences of infectious bronchitis virus three structural protein ( spike protein s membrane protein m nucleocapsid protein n ) genes , the cdna of si gene , s2 gene , m gene . n gene of ib v isolate lx4 were amplified by rt - pcr and full sequences were first reported 在此基础上,根据国内外已发表的ibv基因序列,分别设计特异性引物,应用不同引物进行反转录合成cdna ,分片段对ibv的主要结构基因进行pcr扩增,并分别将各个目的片段克隆到puc19载体上,在大肠杆菌dh5中实现目的基因的分子克隆,经蓝白斑筛选、限制性内切酶分析、 pcr鉴定,筛选出重组阳性质粒,并对各个目的基因片段进行序列测定,从而获得ibv主要结构基因全序列。 |
