Interpretive Summary:

Technical Abstract: Vascular wilt pathogens in the genus Verticillium show considerable variation with respect to their host ranges, genomic organization, and the variety and number of transposable elements (TEs) that they carry. These families of TE sequences were first documented in the wide host range, plant pathogenic species V. dahliae. They have since been shown in V. dahliae to comprise a small number of class I elements (retrotransposons), and relatively larger numbers of genetically diverse class II elements (DNA transposons). Subsequent analysis and use of these sequences in Verticillium research have contributed much to our knowledge of this genus, and particularly of V. dahliae. The TEs are involved not only in sequence transposition, but are also associated with insertions and deletion of genetic material, and consequent inter-and intra-chromosomal rearrangements. Such events have the potential to effect the changes in genome content and structure that have been hypothesized to drive genetic adaptation of V. dahliae to new hosts.
