Commelina mosaic virus

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]

Symptoms and Inclusions of Commelina mosaic virus in Commelina diffusa.

(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. )
