The remarkable evolutionary history of endornaviruses Roossinck, Marilyn J. and Sabanadzovic, Sead and Okada, Ryo and Valverde, Rodrigo A.,, 92, 2674-2678 (2011), doi = https://doi.org/10.1099/vir.0.034702-0, publicationName = Microbiology Society, issn = 0022-1317, abstract= The family Endornaviridae contains several members from diverse hosts, including plants, fungi and oomycetes. They are found as large dsRNA elements with a nick in the coding strand. All members encode a conserved RNA-dependent RNA polymerase, but no other domain that is conserved among all members. Based on the conserved domain database comparison the various domains have different origins, indicating a highly modular evolutionary history. In some cases, domains with similar putative functions are found that are derived from different protein families, indicating convergent evolution for a required function., language=, type=
