text: # Varicosavirus
  
  Varicosavirus is a genus of plant viruses. The virus is associated with swelling in plant vein tissues. They are negative single stranded RNA viruses. The genus contains three species.
  
  ## Taxonomy
  
  The genus contains the following species:
  
  * Alopecurus varicosavirus
  * Lettuce big-vein associated varicosavirus
  * Trifolium varicosavirus
  
  ## 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.
  
  ## 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.
