Commelina mosaic virus (CoMV) is a plant pathogenic virus [1] in the genus Potyvirus and the virus family Potyviridae. Like other members of the Potyvirus genus, CoMV is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein. The virus is a filamentous particle that measures about 707-808 nm in length. This virus is transmitted by two species of aphids, Myzus persicae and Aphis gossypii, and by mechanical inoculation.[2]
Commercial antiserum is not available for this virus. However, diagnosis in this plant can be made by symptoms and by the presence of plate-like inclusions.[3]

(Potyviruses make proteinaceous inclusions in infected plant cells. These inclusions can be seen in the light microscope in leaf strips of infected plant tissue stained with Orange-Green (protein stain) but not Azure A (nucleic acid stain) [4][5] .[6] There are four different kinds of Potyvirus inclusions.[7] (CoMV belongs to group II. )
