摘要:
为研究家蚕杆状病毒(BmNPV)编码的 Bm 122基因的生物学功能,利用Red重组技术和Bac to Bac系统分别构建了Bm122 ko bacmid和Bm122 re bacmid,实现对 Bm 122基因的敲除和异位补回。进而将Bm122 ko bacmid、Bm122re bacmid、wtbacmid(野生型)分别转染BmN细胞,病毒滴度测定结果显示: Bm 122缺失后,病毒无法形成正常水平的芽生型病毒粒子(budded virus,BV),表明该基因是病毒生成有感染力的BV所必需的基因;透射电子显微镜观察发现, Bm 122敲除后细胞内未观察到杆状病毒粒子,进一步证实 Bm 122的缺失影响了BV的生成。qPCR结果显示, Bm 122缺失后病毒DNA复制水平降低。结果表明, Bm 122是病毒生成正常水平的BV所必需的基因。
