Varicosavirus

Varicosavirus is a genus of plant viruses that currently consists of one recognised species: Lettuce big-vein associated varicosavirus. The virus is associated with 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.

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.[2]

gollark: Alternatively, it says you can build it with their `koch` tool.
gollark: * .
gollark: Oh, do you have `~/.nimble/bin` on your path? It mentions this?
gollark: > Nimble is now bundled with Nim (since Nim version 0.15.0). This means that you should have Nimble installed already, as long as you have the latest version of Nim installed as well. Because of this you likely do not need to install Nimble manually.???
gollark: You can do everything nimble does with a bunch of `git clone`s and `nim c` but that's bee.
