Varicosavirus

Description and Significance

Varicosavirus is a nonenveloped, rod-shaped virus with helix symmetry. It infects veins in lettuce leaves and is associated with causing big-vein disease in field-grown lettuce. The type species and only member of the genus is Lettuce big-vein associated virus (LBVaV).

Transmission of the virus is through moist soil via zoospores from an obligate parasitic soil-borne fungus. LBVaV causes deformities in affected leaves that make them unmarketable.
