Marafivirus
''Marafivirus'' is a genus of viruses in the order ''Tymovirales'', in the family ''Tymoviridae''. Plants serve as natural hosts. There are 11 species in this genus. Taxonomy The genus contains the following species: * ''Alfalfa virus F'' * '' Bermuda grass etched-line virus'' * '' Blackberry virus S'' * ''Citrus sudden death-associated virus'' * '' Grapevine asteroid mosaic associated virus'' * '' Grapevine Syrah virus 1'' * '' Maize rayado fino virus'' * '' Nectarine marafivirus M'' * ''Oat blue dwarf virus'' * '' Olive latent virus 3'' * ''Peach marafivirus D'' Structure Viruses in ''Marafivirus'' are non-enveloped, with icosahedral and isometric geometries, and T=3 symmetry. The diameter is around 30 nm. Genomes are linear, around 6-7kb in length. Life cycle Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcript ...

Tymoviridae
''Tymoviridae'' is a family of single-stranded positive sense RNA viruses in the order ''Tymovirales''. Plants serve as natural hosts. There are 42 species in this family, assigned to three genera, with two species unassigned to a genus. Taxonomy The family includes the following three genera: * ''Maculavirus'' * ''Marafivirus'' * ''Tymovirus'' Additionally, the following two species are not assigned to a genus: * ''Bombyx mori latent virus'' * ''Poinsettia mosaic virus'' Proposed viruses * Culex tymovirusWang L, Lv X, Zhai Y, Fu S, Wang D, Rayner S, Tang Q, Liang G (2012) Genomic characterization of a novel virus of the family tymoviridae isolated from mosquitoes. PLoS One 7(7):e39845. * Fig fleck-associated virus Virology The virions are non-enveloped and isometry, isometric with a diameter of around 30 nm, with an icosahedral structure and a Capsid#Triangulation number, triangulation number T=3.
