Description
Peanut mottle virus (PeMoV) is a plant pathogenic virus of the family Potyviridae. As with other members of this virus family, PeMoV is a flexuous filamentous virus with particles 740-750 nm long. It is transmitted by several species of aphids and by mechanical inoculation. It was first given its name in 1965 when it was isolated from peanuts (Arachis hypogaea) in Georgia, USA. This virus was found to be seed transmitted in this host.
The symptoms of this virus in peanuts appear as irregular dark islands on young leaves. The symptoms are not as clear on older leaves and thus can be easily missed even when the virus is in epidemic proportions in the field.
In infected plant cells, the virus makes characteristic potyvirus cylindrical inclusions. that are visible in the light microscope with proper staining
