Pea enation mosaic virus

Pea enation mosaic virus (PEMV) is really two plant pathogenic viruses. The two RNAs of the disease are now categorised as two separate, mutualistic viruses:[1]

Phylum: Kitrinoviricota
Class: Tolucaviricetes
Order: Tolivirales
Family: Tombusviridae
Genus: Umbravirus
Species:
Pea enation mosaic virus 2

They are spread by green- or pea aphids and affects such legumes as pea,[2] alfalfa, broadbean or sweet pea mostly in temperate regions.[1]

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]
