Pea enation mosaic virus
Pea enation mosaic virus is a plant pathogenic 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.
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.
