Beet necrotic yellow vein virus (BNYVV) is a plant virus, transmitted by the plasmodiophorid[1] Polymyxa betae. The BNYVV is a member of the genus Benyvirus[2] and is responsible for rhizomania, a disease of sugar beet (Rhizo: root; Mania: madness) that causes proliferation of thin rootlets, and leads to a smaller tap root with reduced sugar content. Infected plants are less able to take up water, and wilting can be observed during the warm period of the year. If the infection spreads to the whole plant, vein yellowing, necrosis and yellow spots appear on the leaves, giving the virus its name.
