Varicosavirus is a genus of plant viruses. The virus is associated with swelling in plant vein tissues. They are negative single stranded RNA viruses.[1] The genus contains three species.
The genus contains the following species:[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.
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.[3]
