Investigating the Impact of Whole-Genome Duplication on Transposable Element Evolution in Teleost Fishes.

ABSTRACT: Transposable elements (TEs) can make up more than 50% of any given vertebrate's genome, with substantial variability in TE composition among lineages. TE variation is often linked to changes in gene regulation, genome size, and speciation. However, the role that genome duplication events have played in generating abrupt shifts in the composition of the mobilome over macroevolutionary timescales remains unclear. We investigated the degree to which the teleost genome duplication (TGD) shaped the diversification trajectory of the teleost mobilome. We integrate a new high coverage genome of Polypterus bichir with data from over 100 publicly available actinopterygian genomes to assess the macroevolutionary implications of genome duplication events on TE evolution in teleosts.
