bean virus 2
Bean yellow mosaic virus (BYMV) is a plant pathogenic virus  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.
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. 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), peanuts (Arachis hypogaea), soybeans (Glycine max), 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), Black Locust (Robinia pseudoacacia), Fenugreek (Trigonella foenum-graecum),and Crotalaria spectabilis.
