General Description
Tomato black ring virus (TBRV) is a plant pathogenic virus of the family Secoviridae infecting several hosts including potato, almond, caneberry, strawberry, peach and nectarine, grapes and Narcissus.
TBRV is RNA-containing virus which has isometric particles about 30 nm in diameter and occurs in Europe. It is readily sap-transmissible, has a wide host range, infects the seed of many host plants, and is transmitted in soils by nematodes (Longidorus spp.). In addition to black ring of tomato, the various strains of this virus cause ringspot diseases of bean, sugar beet, lettuce, raspberry and strawberry, yellow vein of celery, 'bouquet' and pseudo-aucuba of potato, shoot-stunting of peach, one type of mosaic of Robinia pseudoacacia and unnamed diseases of leek and onion. It occurs in many other plants, including cabbage, grapevine, lucerne and Sambucus nigra.
