Cosupression of Transposable Elements and Hybrid Dysgenesis

We studied a system of hybrid dysgenesis in Drosophila virilis in which at least four unrelated transposable elements are all mobilized following a dysgenic cross. The data are largely consistent with the loss of cosuppression of different families of transposable elements. These families include Ulysses and Telemac (both LTR-containing retrotransposon), Helena (a non-LTR retrotransposon), Paris (a cut-and-paste DNA transposon) and Penelope (a transposable element of uncertain functional affiliation).
