Genomoviridae

Genomoviridae is a family of single stranded DNA viruses that mainly infect fungi. The genomes of this family are small (2.2–2.4 kilobases in length). The genomes are circular single-stranded DNA and encode rolling-circle replication initiation proteins (Rep) and unique capsid proteins. In Rep-based phylogenies, genomoviruses form a sister clade to plant viruses of the family Geminiviridae. Ten genera are 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. Sclerotinia sclerotiorum hypovirulence associated DNA virus 1 (ssHADV-1), of the genus Gemycircularvirus, was the first cultivated member of the family. Most other genomoviruses are uncultivated and have been discovered using metagenomics techniques, although more genomoviruses are being isolated as interest grows.
