White clover mosaic virus (WClMV) is a plant pathogenic virus[1] in the genus Potexvirus and the family Alphaflexiviridae. WClMV is a filamentous, flexuous rod, 480 nm in length and 13 nm wide.
The virus is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made from a single viral encoded protein. The genome has been completely sequenced[2] and is 5845 nucleotides long. It is transmitted by mechanical inoculation, contact between plants and sometimes by seed (6% in Trifolium pratense). No insect vector is known.
Its major host is clover (Trifolium spp).[3] It was first reported in Trifolium repens in 1935.[4] In the western United States and south western Canada it had been found in clover in a mixed infection with another potexvirus, Clover yellow mosaic virus.[5][6] It is also known to infect peas (Pisum sativum), faba beans (Vicia faba), green beans (Phaseolus vulgaris), cowpea (Vigna unguiculata), cucumbers (Cucumis sativus), squash ( Cucurbita pepo ), and tomatoes (Lycopersicon esculentum).[7]
This virus is believed to be distributed in temperate regions worldwide.[8]
