Abstract
Complete genome sequencing of a virus from a white snakeroot plant (Ageratina altissima (L.) King & H. Rob.) collected in the Great Smoky Mountains National Park, USA, revealed a quadricistronic organization resembling that of umbraviruses. ORFs 1 and 2 are putatively translated via a −1 ribosomal frameshift mechanism as a single polypeptide with a role in viral replication, whereas the 3′-proximal and extensively overlapping ORFs 3 and 4 code for proteins involved in long distance trafficing and cell-to-cell movement within the host. Sequence comparisons and phylogenetic analysis strongly suggested that this virus is a previously undescribed member of the genus Umbravirus (family Tombusviridae), for which the name “white snakeroot virus A” (WSVA) is proposed. In addition, we identified and initiated characterization of its possible helper virus, a putative new member of the genus Luteovirus.
期刊介绍:
Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
