Bovine herpesvirus 1 has been reported to contain a thymidine kinase (tk) gene which is nonessential for virus replication. We have isolated a thymidine kinase-negative mutant of the virus and localized the mutation by marker rescue experiments to a 1.1-kilobase BglII-SalI fragment which maps at 0.47 to 0.48 on the bovine herpesvirus 1 genomic map. A thymidine kinase-negative bovine cell line isolated in our laboratory was used in these studies.
据报道,牛疱疹病毒1含有一个对病毒复制非必需的胸苷激酶(tk)基因。我们已分离出该病毒的一个胸苷激酶阴性突变体,并通过标记拯救实验将突变定位到一个1.1千碱基的BglII-SalI片段上,该片段在牛疱疹病毒1基因组图谱上的位置为0.47至0.48。这些研究中使用了我们实验室分离的一个胸苷激酶阴性牛细胞系。
