초록

A polydnavirus, Cotesia plutellae bracovirus (CpBV), is symbiotic to an endoparasitoid wasp, C.plutellae, which specifically parasitizes young larvae of the diamondback moth, Plutella xylostella. A recent study on CpBV replication by analysis of ovary transcriptome of C.Plutellae suggests several candidate coat protein genes. This study was conducted to confirm the coat protein genes by analyzing coat proteins of CpBV viral particles by a tandem mass MALDI-TOF. Immunoprecipitation of ovary protein extract with a polyclonal CpBV antibody captured three proteins named as p35, p60, and p70. More number of coat proteins were resolved in a protein extract directly from viral particles. All candidate coat proteins are analyzed in amino acid sequences by MALDI-TOF. A comprehensive analysis of viral proteomics and ovary transcriptome determined novel viral coat proteins from CpBV
