Transposable elements in phytopathogenic Verticillium spp.: insights into genome evolution and inter- and intra-specific diversification.

ABSTRACT:

Background

Verticillium dahliae (Vd) and Verticillium albo-atrum (Va) are cosmopolitan soil fungi causing very disruptive vascular diseases on a wide range of crop plants. To date, no sexual stage has been identified in either microorganism suggesting that somatic mutation is a major force in generating genetic diversity. Whole genome comparative analysis of the recently sequenced strains VdLs.17 and VaMs.102 revealed that non-random insertions of transposable elements (TEs) have contributed to the generation of four lineage-specific (LS) regions in VdLs.17.

Results

We present here a detailed analysis of Class I retrotransposons and Class II "cut-and-paste" DNA elements detected in the sequenced Verticillium genomes. We report also of their distribution in other Vd and Va is
