Grapevine virus B is plant virus species in the genus Vitivirus . It is associated with rugose wood (corky bark) symptoms in grapevine. [1]
Enterovirus is a genus of positive-sense single-stranded RNA viruses associated with several human and mammalian diseases. Enteroviruses are named by their transmission-route through the intestine.
Echovirus is a polyphyletic group of viruses associated with enteric disease in humans. The name is derived from "enteric cytopathic human orphan virus". These viruses were originally not associated with disease, but many have since been identified as disease-causing agents. The term "echovirus" was used in the scientific names of numerous species, but all echoviruses are now recognized as strains of various species, most of which are in the family Picornaviridae.
Lasiodiplodia theobromae is a plant pathogen with a very wide host range. It causes rotting and dieback in most species it infects. It is a common post harvest fungus disease of citrus known as stem-end rot. It is a cause of bot canker of grapevine. It also infects Biancaea sappan, a species of flowering tree also known as Sappanwood.
Grapevine fanleaf virus (GFLV) is a plant pathogenic virus of the family Secoviridae. It infects grapevines, causing chlorosis of the leaves and lowering the fruit quality. Because of its effect on grape yield, GFLV is a pathogen of commercial importance. It is transmitted via a nematode vector, Xiphinema index. This nematode acquires the virus through feeding on roots of an infected plant, and passes it on in the same manner.
Citrus psorosis ophiovirus is a plant pathogenic virus infecting citrus plants worldwide. It is considered the most serious and detrimental virus pathogen of these trees.
Flavescence dorée is one of the most important and damaging phytoplasma diseases of the vine with the potential to threaten vineyards. The bacterial agent has recently been named Candidatus Phytoplasma vitis, and its vector is the leafhopper, Scaphoideus titanus. Infection may kill young vines and greatly reduce the productivity of old vines. It is classified as a phytoplasma disease belonging to the group generically termed grapevine yellows. Occurrences are in sporadic epidemics, and varieties vary in their sensitivity to it.
Grapevine yellows (GY) are diseases associated to phytoplasmas that occur in many grape growing areas worldwide and are of still increasing significance. The most important grapevine yellows is flavescence dorée.
The hop stunt viroid is a viroid species that infects the common hop plant, citrus plants and grapevines, among others. It is a member of the Pospiviroidae family and the Hostuviroid genus. There are quite a few different sub-species of the hop stunt viroid.
Grapevine leafroll-associated virus (GLRaV) is a name for a group of viruses that infect grapevine.
Grapevine virus A (GVA) is a moderately common genetic virus that affects Vitis vinifera and American Vitis grapevine species throughout the world and can be fatal if not treated. Grapevine virus A is in the family Betaflexiviridae and genus Vitivirus. The common name for this virus is grapevine closterovirus. Common symptoms in infected grapevines include stem pitting. Although there is a treatment available to cure infected grapevines, it is not one hundred percent effective, so preventative measures are the best solution to the virus. Every inhabited continent on the globe has had breakouts of grapevine closterovirus due to the complex genetic makeup of the virus. Grapevine virus A has a single-stranded RNA genome, which is similar to that of Grapevine virus B. There are multiple strains of the virus that vary both molecularly and biologically which account for the slightly different symptoms exhibited by infected plants.
Grapevine virus D (GVB) is a plant virus species in the genus Vitivirus, associated with rugose wood condition of grapevine.
Grapevine leafroll-associated virus 2 (GRLaV2) is a virus infecting grapevine in the genus Closterovirus. It is associated with rugose wood condition of grapevine.According to Bosciai, 1995, grapevine corky bark-associated virus (GCBaV) is a variant of GRLaV2.
Grapevine leafroll-associated virus 3 (GLRaV-3) is a grapevine infecting virus in the family Closteroviridae, genus Ampelovirus.
Ampelovirus is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are 13 species in this genus. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem.
Foveavirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There are eight species in this genus. Diseases associated with this genus include: mosaic and ringspot symptoms.
Velarivirus is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are eight species in this genus. Diseases associated with this genus include: GLRaV-7: symptomless in white-berried grapevine cultivar from Albania. However, it induces leafroll symptoms onto grafted cv. cabernet.
Grapevine red blotch disease (GRBD), also known simply as red blotch, is a viral disease of grapevine. The disease is caused by a single-stranded circular DNA virus, the species grapevine red blotch virus, also known as grapevine red blotch-associated virus, GRBaV. First identified in California, the disease affects grapevines of all varieties and is internationally present. Symptoms typically include red blotches on the leaves of red varieties and in pale green or pale yellow blotches on white varieties. It significantly reduces the value of juice collected from the berries of affected vines, costing vineyard owners as much as $65,000 per acre.
Tomato brown rugose fruit virus (ToBRFV) is a plant virus in the genus Tobamovirus that was first described in 2015. It has spread rapidly since it was first noted in Jordan and Israel. The main hosts are tomato and peppers. The virus causes symptoms including mosaic and distortion of leaves and brown, wrinkly spots (rugose) on fruits. Outbreaks can be severe and leave fruit unmarketable.
Rubodvirus is a recently described plant virus genus belonging to the family Phenuiviridae in the order Bunyavirales. These plant viruses are transmitted from plant to plant through graft transmission.
