Multiple horizontal transfers of a Helitron transposon associated with a parasitoid wasp.

ABSTRACT: In a previous study we described a Helitron transposon that apparently became one of the segments in the symbiotic Cotesia vestalis bracovirus (CvBV) from the parasitoid wasp C. vestalis. We presented evidence that this Helitron, named Hel_c35, invaded the C. vestalis genome through a horizontal transfer (HT) event from a dipteran and was later transferred horizontally from C. vestalis to a lepidopteran species. Based on the phylogeny of Hel_c35, we suggested that both HTs occurred in East Asia. We have also anticipated that, as more sequenced genomes from new species become available, more HTs involving Hel_c35 would be detected. Although the inclusion of Hel_c35 as a CvBV segment turned out to be a methodological artifact, the fact that Hel_c35 copies are present in the genomes of C. ves
