Abstract:
The phylum Basidiomycota includes filamentous fungi and yeast species with different ecological and genomic characteristics. Transposable elements (TEs) are abundant components of most eukaryotic genomes, and their transition from being genomic parasites to key drivers of genomic architecture, functionality, and evolution is a subject receiving much attention. In light of the abundant genomic information released during the last decade, the aims of this mini-review are to discuss the dynamics and impact of TEs in basidiomycete fungi. To do this, we surveyed and explored data from 75 genomes, which encompass the phylogenetic diversity of the phylum Basidiomycota. We describe annotation approaches and analyze TE distribution in the context of species phylogeny and genome size. Further, we review the most relevant literature about the role of TEs in species lifestyle, their impact on genome architecture and functionality, and the defense mechanisms evolved to control their proliferation. Finally, we discuss potential applications of TEs that can drive future innovations in fungal research.
