Aureusvirus is a genus of viruses, in the family Tombusviridae . Plants serve as natural hosts. There are six species in this genus. [1] [2]
The genus contains the following species: [2]
Viruses in Aureusvirus are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The diameter is around 30 nm. Genomes are linear, around 4.4kb in length. [1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Aureusvirus | Icosahedral | T=3 | Non-enveloped | Linear | Monopartite |
Viral replication is cytoplasmic, and is lysogenic. 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, using the premature termination model of subgenomic RNA transcription is the method of transcription. Translation takes place by leaky scanning, and suppression of termination. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. Transmission routes are mechanical, seed borne, and contact. [1]

Tombusviridae is a family of single-stranded positive sense RNA plant viruses. There are three subfamilies, 17 genera, and 95 species in this family. The name is derived from Tomato bushy stunt virus (TBSV).
Furovirus is a genus of viruses, in the family Virgaviridae. Graminae, winter wheat, wheat, triticale, oat, sorghum bicolor, and plants serve as natural hosts. There are six species in this genus. Diseases associated with this genus include: (SBWMV): green and yellow mosaic.
Tombusvirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There are 17 species in this genus. Symptoms associated with this genus include mosaic. The name of the genus comes from Tomato bushy stunt virus.
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.
Dianthovirus is a genus of viruses, in the family Tombusviridae. Dianthoviruses are plant viruses. There are three species in this genus. The virus probably has a worldwide distribution, and can be transmitted via nematodes, by mechanical inoculation, by grafting of plants and by contact between infected hosts with previously uninfected host.
Tobravirus is a genus of viruses, in the family Virgaviridae. Plants serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: SBWMV: green and yellow mosaic.
Cucumovirus is a genus of viruses, in the family Bromoviridae. Plants serve as natural hosts. There are four 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.
Qubevirus is a genus of positive-strand RNA viruses, in the family Fiersviridae. Enterobacteria serve as natural hosts. There are two species in this genus. In 2020, the genus was renamed from Allolevivirus to its current name.
Avenavirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There is only one species in this genus: Oat chlorotic stunt virus.
Enamovirus is a genus of viruses, in the family Solemoviridae. Plants serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: pea enation disease: if both PEMV-1 and PEMV-2 are present.
Panicovirus is a genus of viruses, in the family Tombusviridae. Panicae serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: systemic mosaic.
Polerovirus is a genus of viruses, in the family Solemoviridae. Plants serve as natural hosts. There are 26 species in this genus. Diseases associated with this genus include: PLRV causes prominent rolling of the leaves of potato and a stiff upright habit of the plants; necrosis of the phloem and accumulation of carbohydrates in the leaves.
Rymovirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are three species in this genus.
Tritimovirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are six 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.
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.
Zeavirus is a genus of viruses, in the family Tombusviridae. Monocots plants serve as natural hosts. There is only one species in this genus: Maize necrotic streak virus.
