Microplitis demolitor bracovirus transcription in infected hosts

Polydnaviruses in the genus Bracovirus (BV) are associated with parasitoid wasps in the family Braconidae. BV-carrying wasps rely on their associated viruses to parasitize permissive hosts but also occasionally oviposit into host species that are non-permissive. Here, we studied Microplitis demolitor and M. demolitor bracovirus (MdBV) in Chrysodeixis includens, a permissive host, and Trichoplusia ni, which is usually non-permissive. These deep sequencing data quantify transcript abundance for viral genes in C. includens and T. ni.

茧蜂病毒属（Bracovirus，BV）的多分DNA病毒（Polydnaviruses）与茧蜂科（Braconidae）寄生蜂存在共生关联。携带BV的寄生蜂依赖其共生病毒才能完成对易感宿主（permissive host）的寄生，同时偶尔也会将卵产至非易感宿主（non-permissive host）物种体内。本研究以螟黄足盘绒茧蜂（Microplitis demolitor）及其共生病毒螟黄足盘绒茧蜂多分DNA病毒（MdBV）为研究对象，分别选取易感宿主大豆尺夜蛾（Chrysodeixis includens）以及通常为非易感宿主的粉纹夜蛾（Trichoplusia ni）作为实验材料。本研究获得的深度测序（deep sequencing）数据可量化分析两种宿主体内病毒基因的转录本丰度。
