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 with no specific assigned family. Infection occurs through soil by the spores of the fungus Olpidium brassicae.
Genome
The genome 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.
