“…Since viral transcription has been observed in host after parasitization (Blissard et al, 1986a,b;Strand et al, 1992;Hayakawa et al, 1994;Trudeau and Strand, 1998;Cui et al, 2000), the expression time and pattern vary in many polydnavirus-host systems. For CsIV, C. sonorensis developed endoparasitically and at least 12 viral mRNAs were detected (Fleming et al, 1983;Blissard et al, 1986b).…”

Polydnavirus was isolated from oviduct calyx in the parasitoid wasp Campoletis chlorideae (Hymenoptera: Ichneumonidae), and termed CcIV. The virus particles consist of fusiform nucleocapsids surrounded by two unit membrane envelopes. The DNAs purified from these viruses were found diversified in molecular weight and existed in nonequimolar concentrations. At least 20 different-sized bands were present after electrophoresis, and they ranged from approximately 3 to 26 kb. Persistence and gene expression of CcIV were examined in parasitized and virus-injected Helicoverpa armigera larvae. Viral DNA could be detected in the hemocyte of H. armigera at 30 min post-parasitization (p.p.), and persisted for 6 days. While no viral DNA increase was found, CcIV transcripts were first detected in host hemocytes at day 1 p.p. and continued for 5 days. Similar transcripts were observed in hemocytes from larvae that had been injected with calyx fluid or CcIV 24 h earlier. CcIV viral DNAs hybridized only with certain first-strand cDNAs from hemocytes, suggesting that only part of the CcIV genome was expressed in H. armigera. The pattern of CcIV gene expression was consistent with that of the inhibition of encapsulation for Sephadex G-10 and parasitoid eggs by host larvae. The recovery of host immune response at day 4 p.p. indicated that CcIV exhibited a partial and temporal effect on the host immune system and the developing parasitoid appeared to avoid encapsulation via different mechanisms.

“…The genome of Campoletis sonorensis ichnovirus (CsIV) contains five gene families, cysteine motif, vankyrin, repeat element, N family, and vinnexin, and a putative sixth family, encoding polar-residue-rich proteins (53,60). While the cysteine motif (12,36) and vankyrin (31,32) proteins have been linked to disruption of host immunity, the roles of the other gene families have not been reported. The vinnexins (Vnx) are homologous to the innexins (54,55), one of two gene families which encode the structural units of gap junctions.…”

“…These multigene families were characterized based on similarities in sequence, protein structure, expression pattern and function (Cui, Soldevila, and Webb, 1997;Cui, Soldevila, and Webb, 2000;Cui and Webb, 1996;Kroemer and Webb, 2005). Here we focus on the viral ankyrin or vankyrin gene family, in C. sonorensis IV.…”
