| 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.
Genome
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]
Structure
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.
