The rapid rates of viral evolution allow us to reconstruct the recent history of viruses in great
detail. This feature, however, also results in rapid erosion of evolutionary signal within viral …

Endogenous retroviruses are a common ancestral feature of mammalian genomes with most
having been inactivated over time through mutation and deletion. A group of more intact …

Viruses of the subfamily Orthoretrovirinae are defined by the ability to reverse transcribe an
RNA genome into DNA that integrates into the host cell genome during the intracellular virus …

Summary Antisense Piwi-interacting RNAs (piRNAs) guide silencing of established
transposons during germline development, and sense piRNAs drive ping-pong amplification …

Koala retrovirus (KoRV) is a newly described endogenous retrovirus and is unusual in that
