==Description and significance==
Tomato Black Ring Virus (TBRV) is a RNA-containing virus which as isometric particles about 30nm in diameter and occurs in Europe. It infects a wide range of herbaceous and wood monocotyledonous and dicotyledonous species including many that are important crop plants. In addition to black ring of tomato, the various strains of this virus cause ringspot diseases of bean, sugarbeet, lettuce, raspberry and strawberry, yellow vein of celery,shoot-stunting of peach and unnamed diseases of leek and onion. It occurs in many other plants, including cabbae, grapevine and lucerne.
Describe the appearance, habitat, etc. of the organism, and why you think it is important.
