Bean yellow mosaic virus (BYMV) is a plant pathogenic virus[1] in the genus Potyvirus and the virus family Potyviridae. Like other members of the Potyvirus genus, BYMV is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein. The virus is a filamentous particle that measures about 750 nm in length. This virus is transmitted by species of aphids and by mechanical inoculation.[2]

Geographic distribution and host range

A mosaic disease, believed to be BYMV, was first reported in the early 1900s infecting garden peas (Pisum sativum) in the Northeastern United States.[3] Today the virus is believed to be distributed worldwide.

In addition to peas this virus is known to infect many other legumes (family Fabaceae) including green beans (Phaseolus vulgaris),[4] peanuts (Arachis hypogaea),[5] soybeans (Glycine max),[6] Faba beans (Vicia faba), several species of clover (Trifolium hybridum, T. vesiculosum, T. incarnatum, T. pratense, T. repens, T. subterraneum), alfalfa (Medicago sativa), vetch (Vicia sativa), lupine (Lupinus luteus),[7] Black Locust (Robinia pseudoacacia), Fenugreek (Trigonella foenum-graecum), and Crotalaria spectabilis.

It also is known to infect several non-leguminous plants including Gladiolus sp.,[8] Fressia sp., Opium Poppy (Papaver somniferum), Canna spp. and Eustoma russellianum.

Symptoms in these plants include mosaic, leaf malformation and leaf mottling.[9] This virus makes two kinds of viral inclusions, laminiated aggregates and a nuclear inclusion.[1]
