Interpretive Summary: Pea enation mosaic virus (PEMV) was first reported in 1914 in Delaware and is an important virus on pea worldwide. Alternative hosts for this virus are primarily confined to the Fabaceae family. Major yield losses in U.S. pea production areas of the Pacific Northwest occur every 5 to 9 years. Symptoms of the virus include translucent spots and vein clearing associated with affected leaves. Plants and pods of infected plants are often stunted and distorted. PEMV is caused by the combination of an obligate single-stranded RNA positive-sense enamovirus and umbravirus. PEMV is transmitted by at least 13 aphid species but can also be mechanically transmitted. There are mixed results on whether PEMV is seed transmitted or only seedborne. PEMV is managed by elimination of aphid vectors and host genes that provide either tolerance or resistance to the virus.
