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.[1][2] 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.[1][2] The type species of the genus Gemycircularvirus—Sclerotinia sclerotiorum hypovirulence associated DNA virus 1—is currently the only cultivated member of the family.[3] The other genomoviruses are uncultivated and have been discovered using metagenomics techniques.[4] TaxonomyThe genera in this family are:[4]
BiologyThese viruses have single stranded genomes of 2.1–2.2 kilobases in length. The genome encodes two proteins—a Rep (replicator) and a CP (capsid) protein. The Rep protein has some homology with the Rep protein of the Geminiviridae. In contrast the CP protein has no known homologies.
