Virus classification
Group: Group V ((−)ssRNA)
Order: Mononegavirales
Family: Rhabdoviridae
Genus: Varicosavirus
Species: Lettuce big-vein associated varicosavirus

The genus Varicosavirus is a group of related plant viruses associated with the swelling in plant vein tissues. They are negative single stranded RNA[1] viruses. Infection occurs through soil by the spores of the fungus Olpidium brassicae.


The genome of the only member of the only species of this genus (lettuce big-vein associated virus (LBVaV)) consists of a bi-segmented linear, single-stranded negative sense RNA. The first segment is about 6350–7000 nucleotides in length; the second, about 5630–6500 nucleotides in length.[2]


Virions consist of a non-enveloped rod-shaped capsid, having a helical symmetry of 120–360 nm in length, and a width of 18–30 nm.
