Turnip yellow mosaic virus (TYMV) is an isometric tymovirus of the family Tymoviridae. Its host range is confined almost entirely to plants in the Brassica genus in western Europe, which includes cabbages, cauliflower and broccoli. Infection causes bright yellow mosaic disease showing vein clearing and molting of plant tissues.
