title: Polydnavirus genome segment families in the ichneumonid parasitoid Hyposoter fugitivus.
abstract: Sequences homologous to encapsidated polydnavirus genome segments are routinely detected in parasitoid chromosomal DNA; typically, each viral genome segment hybridizes to a single cognate chromosomal locus. In the present study, we show that in some cases, two or more viral genome segments may hybridize to the same chromosomal locus. Genome segments of this type invariably share a majority of restriction enzyme sites, a fact suggesting derivation from a common template. Families of viral genome segments appear to be relatively common in the Hyposoter fugitivus polydnavirus genome.
