Pea enation mosaic virus

Pea enation mosaic virus (PEMV) is a plant pathogenic virus.[1]

Pea enation mosaic virus (PEMV)
Virus classification
Group:
Group IV ((+)ssRNA)
Order:
Unassigned
Family:
Luteoviridae
Genus:
Enamovirus
Species:
Pea enation mosaic virus

The two RNAs of the disease are now categorised as two separate, mutualistic viruses: PEMV-1 is an Enamovirus, while PEMV-2 is an Umbravirus.

It is spread by green or pea aphids and affects legumes as pea, alfalfa, broadbean or sweet pea mostly in temperate regions.[2]

Symptoms include chlorotic, translucent or necrotic lesions, malformation of leaves and stipules, and plant distortion. However, the most characteristic symptom is the formation of enations on the abaxial, i.e. downy, leaf side. Enations are derived from the cells of vascular bundles undergoing hyperplasia.[3]
