Abstract
Citrus is one of the most widely cultivated and economically important fruit crops globally. However, the postharvest pathogen Penicillium digitatum causes green mold decay in citrus fruits, leading to significant economic losses. Here, a novel mycovirus, Penicillium digitatum mitovirus 1 (PdMV1), was isolated from the phytopathogenic fungus P. digitatum, and its molecular characteristics were determined. PdMV1 has a genome that is 2,517 nt in length with an A+U content of 62.7%. The single ORF encodes a putative RNA-dependent RNA polymerase (RdRp) of 734 amino acids with a molecular mass of 84.116 kDa. A BLASTp comparison of the RdRp sequence showed the highest similarity (65.01% identity) to that of Sclerotinia sclerotiorum mitovirus 32. Phylogenetic analysis revealed that PdMV1 is a new member of the genus Unuamitovirus within the family Mitoviridae. To the best of our knowledge, this is the first report of a mitovirus infecting Penicillium digitatum.
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.
