Complete genome sequence of tobacco mosqueado virus

We describe the genomic characteristics of a new potyvirus isolated from tobacco plants showing mottling ("mosqueado" in Portuguese) in southern Brazil. The complete genomic sequence consists of 9896 nucleotides, without the poly(A) tail, and shares the highest pairwise nucleotide sequence identities of 68.5 % with pepper yellow mosaic virus and 68.2 % with Brugmansia mosaic virus isolate D437. These identity values are below the level of 76.0 % used as a criterion for species demarcation in the genus Potyvirus based on the complete genome sequence. The viral genomic organization and sequence comparison thus suggest that this virus, tentatively named "tobacco mosqueado virus" (TMosqV), represents a new potyvirus species.
