Abstract:
Transposable elements are ubiquitous genomic elements across the eukaryotic tree of life. Since their first discovery, growing evidence demonstrates that transposable elements have a great impact on genome evolution to the extent of representing a driving force for rapid adaptation. In fungi, transposable elements content varies with fungal life-styles, population demography and the efficacy of genomic defenses. Transposable elements activity drives genetic variability either directly, by insertion in coding or regulatory regions, or indirectly, by triggering epigenetic modifications. This article aims at providing an overview of how coevolution between transposable elements and host genomes have shaped fungal genome evolution, architecture and plasticity.
