Beet soil-borne mosaic virus (BSBMV)
This Benyvirus infects beet and is transmitted by the soil-inhabiting fungus Polymyxa betae. Infected plants show leaf symptoms with light yellow vein banding, mottling, and mosaic patterns. Growth of the plants may be reduced, but the roots appear normal, unlike in the closely related Beet necrotic yellow vein virus, which causes rhizomania symptoms.
BSBMV is widely distributed and has been mainly reported in mixed infections, together with other members of the genus Benyvirus (Wisler et al., 2003). Yield losses caused by BSBMV have not been thoroughly studied, but are assumed to be small.
