Genomoviridae


Genomoviridae is a family of single stranded DNA viruses. The genomes of this family are small. The genomes are circular single-stranded DNA and encode rolling-circle replication initiation proteins and unique capsid proteins. In Rep-based phylogenies, genomoviruses form a sister clade to plant viruses of the family Geminiviridae. Nine genera are currently recognized in this family.
The family name is an acronym derived from geminivirus-like, no movement protein.
The genus name Gemycircularvirus stands for Gemini-like myco-infecting circular virus. The type species of the genus Gemycircularvirus—Sclerotinia sclerotiorum hypovirulence associated DNA virus 1—is currently the only cultivated member of the family. The other genomoviruses are uncultivated and have been discovered using metagenomics techniques.

Taxonomy

The genera in this family are:
These viruses have single stranded genomes of 2.1–2.2 kilobases in length. The genome encodes two proteins—a Rep and a CP protein. The Rep protein has some homology with the Rep protein of the Geminiviridae. In contrast the CP protein has no known homologues.
