Abstract
Using degenerate primers and an overlap PCR approach, we identified a new densovirus (family Parvoviridae, subfamily Densovirinae) in an asexual clone of the leaf-curl plum aphid, Brachycaudus helichrysi, collected in Baoji, China, in June 2021. A nearly complete genome sequence of 5,551 nucleotides (nt) was obtained. The virus, with the proposed name “Brachycaudus helichrysi densovirus” (BhDV), has an ambisense genome organization with two ORFs in the sense strand encoding the nonstructural proteins NS1 and NS2 and one ORF at the antisense strand encoding the virion capsid protein VP. These proteins share 37–70% and 10–33% amino acid sequence identity with homologs of the other aphid densoviruses and non-aphid densoviruses, respectively. Phylogenetic analysis suggested that this virus is a member of a new species in the genus Hemiambidensovirus.
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.
