Accumulation and ineffective silencing of transposable elements on an avian W Chromosome.

ABSTRACT: One of the defining features of transposable elements (TEs) is their ability to move to new locations in the host genome. To minimize the potentially deleterious effects of de novo TE insertions, hosts have evolved several mechanisms to control TE activity, including recombination-mediated removal and epigenetic silencing; however, increasing evidence suggests that silencing of TEs is often incomplete. The crow family experienced a recent radiation of LTR retrotransposons (LTRs), offering an opportunity to gain insight into the regulatory control of young, potentially still active TEs. We quantified the abundance of TE-derived transcripts across several tissues in 15 Eurasian crows (Corvus (corone) spp.) raised under common garden conditions and find evidence for ineff
