Tyrosine recombinase elements (YREs) are relatively rare and poorly understood, despite sharing characteristics with both DNA and RNA elements. Previously, the Nematoda have been reported to have a substantially different diversity of YREs compared to other animal phyla: the Dirs1-like YRE retrotransposon was encountered in most animal phyla but not in Nematoda, and a unique Pat1-like YRE retrotransposon has only been recorded from Nematoda. We explored the diversity of YREs in Nematoda by sampling broadly across the phylum and including 34 genomes representing the three classes within Nematoda. We developed a method to isolate and classify YREs based on both feature organization aPloS oneThe evolution of tyrosine-recombinase elements in Nematoda.PMC4157794NE/J011355/1NE/J009423/1NBAF010003G0900740Lunt DHKoutsovoulos GBlaxter MLSzitenberg AfalseThe evolution of tyrosine-recombinase elements in Nematoda.Transposable elements can be categorised into DNA and RNA elements based on their mechanism of transposition.
