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: Matlab has a genetic-algorithm-thing builtin? And it isn't concurrent? Weird.
gollark: What I meant was that you could change your code to use parfor or something when iterating over the possible configurations at each stage.
