Abstract

Aspergillus flavus partitivirus 2 (AfPV2) isolate XC-8 from the fungus Aspergillus flavus strain XC-8 was sequenced and analyzed. AfPV2 contains four segments, dsRNA1 to 4. dsRNA1 is 1907 bp in length with an open reading frame (ORF) encoding a putative RNA-dependent RNA polymerase (RdRp) of 565 amino acids (aa). dsRNA2 is 1936 bp in length with an ORF encoding a putative capsid protein (CP) of 508 aa. dsRNA3 is 1799 bp in length with an ORF encoding a hypothetical protein of 482 aa. dsRNA4 is 1650 bp in length with an ORF encoding a hypothetical protein of 400 aa. Phylogenetic analysis showed that AfPV2 is a member of the genus Alphapartitivirus of the family Partitiviridae. BLASTp analysis showed that AfPV2 isolate XC-8 belongs to the same species as AfPV2 isolate UniPR6, which only has two dsRNA segments (GenBank nos. MZ600060.1 and MZ600061.1). Infection by AfPV2 isolate XC-8 did not cause any obvious significant phenotypic changes in A. flavus.

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.
