Characterization of mint virus C, a new member of the genus Carlavirus
Here, we report the complete genome sequence of a new carlavirus causing mosaic on mint plants in Italy, which we have tentatively named "mint virus C" (MVC). Flexuous particles of around 600 nm were observed using transmission electron microscopy, and next-generation sequencing was performed to determine the nucleotide sequence of the MVC genome, which was found to be 8558 nt long, excluding the poly(A) tail, and shows the typical organization of a carlavirus. The putative proteins encoded by MVC are 44–56% identical to the closest matches in the NCBI database, suggesting that MVC should be considered a member of a new species in the genus Carlavirus. MVC was detected in independent mint samples from different regions of Italy, collected in 2023 and 2024. Two MVC isolates, identified in 2023 (Me1) and in 2024 (Me2), have been included in the Plant Virus Italy (PLAVIT) collection.
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.
