Tepovirus is a genus of viruses in the order Tymovirales , in the family Betaflexiviridae . Plants as well as some other root and tuber crops in the andes serve as natural hosts. There are two species in this genus. [1] [2]
The following species are assigned to the genus: [2]
Viruses in Tepovirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12 nm. Genomes are linear, around 6.5kb in length. The genome codes for 3 proteins. [1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Tepovirus | Filamentous | Non-enveloped | Linear | Monopartite |
Viral replication is cytoplasmic. 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 transcription. Plants as well as some other root and tuber crops in the Andes serve as the natural host. Transmission routes are seed borne and pollen associated. [1]

Closteroviridae is a family of viruses. Plants serve as natural hosts. There are four genera and 59 species in this family, seven of which are unassigned to a genus. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem.
Closterovirus, also known as beet yellows viral group, is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are 17 species in this genus. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem. This genus has a probably worldwide distribution and includes among other viral species the Beet yellows virus and Citrus tristeza virus, rather economically important plant diseases. At least some species require vectors such as aphids or mealybugs for their transmission from plant to plant.
Nepovirus is a genus of viruses in the order Picornavirales, in the family Secoviridae, in the subfamily Comovirinae. Plants serve as natural hosts. There are 40 species in this genus. Nepoviruses, unlike the other two genera in the subfamily Comovirinae, are transmitted by nematodes.
Pomovirus is a genus of viruses, in the family Virgaviridae. Plants and dicotyledons serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: dwarfing of shoots (mop-top) and potato spraing disease. The name of the genus is derived from Potato mop-top virus, Potato mop-top virus, giving rise to Pomovirus.
Trichovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants, specifically angiosperms such as pome fruits, citrus, and pear, serve as natural hosts for this plant pathogen. There are seven species in this genus.
Alphaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 65 species in this family, assigned to six genera. Diseases associated with this family include: mosaic and ringspot symptoms.
Betaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 108 species in this family, assigned to 13 genera in two subfamilies. Diseases associated with this family include mosaic and ringspot symptoms.
Gammaflexiviridae is a family of viruses in the order Tymovirales. Fungi serve as natural hosts. There is only one genus in the family, Mycoflexivirus, which has one species: Botrytis virus F.
Macluravirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are ten species in this genus.
Brambyvirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There is only one species in this genus: Blackberry virus Y.
Capillovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants, pome fruits, citrus, and pear serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: abnormal graft union, possibly black necrotic leaf spot disease.
Comovirus is a genus of viruses in the order Picornavirales, in the family Secoviridae, in the subfamily Comovirinae. Plants serve as natural hosts. There are 15 species in this genus.
Rymovirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are three species in this genus.
Tymovirus is a genus of viruses in the order Tymovirales, in the family Tymoviridae. Plants serve as natural hosts. There are 28 species in this genus.
Carmotetraviridae is a family of positive-strand RNA viruses. There is only one genus in this family, Alphacarmotetravirus, which has one species: Providence virus. Lepidopteran insects serve as natural hosts.
Alphanecrovirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There are four species in this genus.
Betanecrovirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There are three species in this genus.
Citrivirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There is only one species in this genus: Citrus leaf blotch virus.
Gallantivirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There is only one species in this genus: Galinsoga mosaic virus. Diseases associated with this genus include: chlorotic or necrotic local lesions, systemic mosaic; leaf malformation.
Macanavirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There is only one species in this genus: Furcraea necrotic streak virus. Diseases associated with this genus include: macana disease.
