Mosquito long non-coding RNAs are enriched with Transposable Elements.

ABSTRACT: Long non-coding RNAs (lncRNAs) lack coding capacity and mounting evidence suggests that they have a regulatory role in diverse organisms. Most knowledge about lncRNAs comes from studies on vertebrates, including a structural association between lncRNAs and transposable elements (TEs). TE sequences are genomic parasites found in all branches of life and are particularly active and abundant in insect genomes. Here we investigate the contribution of TEs to lncRNA biogenesis in Aedes albopictus and Culex quinquefasciatus. We found that a large fraction of lncRNA loci co-occurs with TE loci in both species. Around 40% of A. albopictus and 52% of C. quinquefasciatus lncRNAs show some association with TEs. Most of the lncRNA/TE associations are represented by TE-derived sequences that are express
