Benyvirus is a genus of viruses, in the family Benyviridae. [2] [3] Plants serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: BNYVV: rhizomania. [3] [4] [5]
Viruses in the genus Benyvirus are non-enveloped, with rod-shaped geometries. The diameter is around 20 nm, with a length of 85–390 nm. Genomes are linear and segmented, around 6.7kb in length. [3] [4]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Benyvirus | Rod-shaped | Non-enveloped | Linear | Segmented |
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. The virus exits the host cell by tripartite non-tubule guided viral movement. Plant serve as the natural host. The virus is transmitted via a vector (protozoan). Transmission routes are vector. [3] [4]

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).
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.
Crinivirus, formerly the lettuce infectious yellows virus group, is a genus of viruses, in the family Closteroviridae. They are linear, single-stranded positive sense RNA viruses. There are 14 species in this genus. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem.
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.
Luteovirus is a genus of viruses, in the family Tombusviridae. There are 13 species in this genus. Plants serve as natural hosts. The geographical distribution of Luteoviruses is widespread, with the virus primarily infecting plants via transmission by aphid vectors. The virus only replicates within the host cell and not within the vector. The name 'luteovirus' arises from the Latin luteus, which is translated as 'yellow'. Luteovirus was given this name due to the symptomatic yellowing of the plant that occurs as a result of infection.
Fijivirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Plants serve as natural hosts. Diseases associated with this genus include: galls (tumours) in infected plants and Fiji disease, with severe stunting, deformation and death. The group name derives from Fiji island the place where the first virus was isolated. There are nine species in this genus.
Cheravirus is a genus of viruses in the order Picornavirales, in the family Secoviridae. Plants serve as natural hosts. There are five species in this genus.
Pecluvirus is a genus of viruses, in the family Virgaviridae. Cereal crops and graminaceous weeds serve as natural hosts. There are two species in this genus. Diseases associated with this genus include: (SBWMV): green and yellow mosaic. The name of the genus is derived from Peanut clump virus: Peanut clump virus, giving rise to Pecluvirus.
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.
Sadwavirus is a genus of viruses in the order Picornavirales, in the family Secoviridae. Plants serve as natural hosts. There are three subgenera and five species in this genus. Diseases associated with this genus include: satsuma dwarf virus disease which causes spoon-shaped leaves on citrus tree. Symptoms are enations, multiple flushing, stunting or dwarfing, reduction in number and size of leaves and fruits. The name of this genus comes from one of its species: Satsuma dwarf virus.
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.
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.
Endornaviridae is a family of viruses. Plants, fungi, and oomycetes serve as natural hosts. There are 31 species in this family, assigned to 2 genera. Members of Alphaendornavirus infect plants, fungi and the oomycete Phytophthora sp., members of Betaendornavirus infect ascomycete fungi.
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.
Aquabirnavirus is a genus of viruses, in the family Birnaviridae. Salmonid fish serve as natural hosts. There are three species in this genus. A disease associated with this genus, Infectious pancreatic necrosis (IPN) in salmonid fish, causes significant losses to the aquaculture industry. Chronic infection in adults, and acute viral disease in young salmonid fish can occur.
Bymovirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are six species in this genus.
Oryzavirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Member viruses infect plants and are transmitted by planthoppers. Diseases associated with this genus include: rice stunting, enations on veins of leaves and leaf sheaths, ragged leaves, and flower suppression. There are two species in this genus.
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.
Torradovirus is a genus of viruses in the order Picornavirales, in the family Secoviridae. Plants serve as natural hosts. There are six species in this genus. Diseases associated with this genus include: torrado disease: severe necrosis of leaves and fruits.
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.
