Sclerotinia gemycircularvirus 1 is a single stranded DNA virus with a circular genome that infects the fungus Sclerotinia sclerotiorum.[1] Infection with this virus decreases the virulence of this fungus. The mechanism of this effect is not known.

Virology

[edit]

The virions are isometric particles, 20–22 nanometers in diameter. The capsid is composed on the viral coat protein (VCP).

Genome

[edit]

The genome encodes only two proteins—a replicase and the coat protein. The genes are encoded on complementary strands.

Taxonomy

[edit]

This virus appears to be related to but distinct from members of the Geminiviridae. Unlike geminiviruses, this virus does not have a movement protein. It has been officially classified into the genus Gemycircularvirus within the new family Genomoviridae.[2]
