Bean yellow mosaic virus

Bean yellow mosaic virus is a plant pathogenic virus[1] in the genus Potyvirus and the virus family Potyviridae. Like other members of the Potyvirus genus, it 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 bean yellow mosaic virus, was first reported in the early 1900s infecting garden peas (Pisum sativum) in the Northeastern United States.[3] The virus is currently believed to be distributed worldwide.[4]

In addition to peas, this virus is known to infect many other legumes (family Fabaceae) including green beans (Phaseolus vulgaris),[5] peanuts (Arachis hypogaea),[6] soybeans (Glycine max),[7] 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),[8] black locust (Robinia pseudoacacia), fenugreek (Trigonella foenum-graecum), and Crotalaria spectabilis.

It also is known to infect several non-leguminous plants including Gladiolus sp.,[9] Fressia sp., opium poppy (Papaver somniferum), Canna spp. and Eustoma russellianum.

Symptoms in these plants include mosaic, leaf malformation and leaf mottling.[10] This virus makes two kinds of viral inclusions, laminated aggregates and a nuclear inclusion.[1]
