Highlights•Endogenous viral elements (EVEs) account for a substantial fraction (∼ 10%) of
mammalian genomes.•EVEs represent an abundant source of coding and noncoding …

Mammalian genomes have accumulated millions of retrotransposed sequences during
evolution. This material can be divided into long terminal repeat (LTR) retrotransposons that …

Bats are distinctive among mammals due to their ability to fly, use laryngeal echolocation,
and tolerate viruses. However, there are currently no reliable cellular models for studying bat …

It is becoming clear that most eukaryotic transposable elements (TEs) owe their evolutionary
success in part to horizontal transfer events, which enable them to invade new species …

Transposable elements are the largest individual constituent of mammalian genomes.
These elements are highly diverse, a consequence of the multiplicity of genomic habitats …

Abstract Background Human endogenous retroviruses (HERVs) occupy a substantial
fraction of the genome and impact cellular function with both beneficial and deleterious …

Horizontal transfer of transposable elements (TEs) is an important mechanism contributing
to genetic diversity and innovation. Bats (order Chiroptera) have repeatedly been shown to …

Despite a small genome size, bats have comparable diversity of retroviral and non-retroviral
endogenous sequences to other mammals. These include Class I and Class II retroviral …

Little is known about the evolution of repeated sequences over long periods of time. Using
two independent approaches, we show that the majority of the repeats found in the …

Rolling-circle transposons (Helitrons) are a newly discovered group of mobile DNA
widespread in plant and invertebrate genomes but limited to the bat family Vespertilionidae …
