Deep sequencing identifies viral and wasp genes with potential roles in replication of Microplitis demolitor Bracovirus.

ABSTRACT: Viruses in the genus Bracovirus (BV) (Polydnaviridae) are symbionts of parasitoid wasps that specifically replicate in the ovaries of females. Recent analysis of expressed sequence tags from two wasp species, Cotesia congregata and Chelonus inanitus, identified transcripts related to 24 different nudivirus genes. These results together with other data strongly indicate that BVs evolved from a nudivirus ancestor. However, it remains unclear whether BV-carrying wasps contain other nudivirus-like genes and what types of wasp genes may also be required for BV replication. Microplitis demolitor carries Microplitis demolitor bracovirus (MdBV). Here we characterized MdBV replication and performed massively parallel sequencing of M. demolitor ovary transcripts. Our results indicated that MdBV repl
