Potexvirus
''Potexvirus'' is a genus of pathogenic viruses in the order ''Tymovirales'', in the family ''Alphaflexiviridae''. Plants serve as natural hosts. There are 52 species in this genus, three of which are assigned to a subgenus. Diseases associated with this genus include: mosaic and ringspot symptoms. The genus name comes from ''POTato virus X''). Taxonomy ''Potexvirus'' contains one subgenus that has three species and 49 additional species unassigned to a subgenus. The following 52 species are assigned to the genus, listed by scientific name and followed by their common names: * Subgenus: '' Mandarivirus'' ** ''Potexvirus citriflavimaculae'', Citrus yellow mottle-associated virus ** ''Potexvirus citriflavivenae'', Citrus yellow vein clearing virus ** '' Potexvirus citrindicum'', Indian citrus ringspot virus The following species are unassigned to a subgenus: * ''Potexvirus alternantherae'', Alternanthera mosaic virus * ''Potexvirus babaci'', Babaco mosaic virus * ''Potexvir ...

Lily Virus X
Lily virus X (LVX) is a pathogenic ssRNA(+) plant virus of the family ''Alphaflexiviridae'' and the order ''Tymovirales''. Description LVX is described in the 4th report of the International Committee on Taxonomy of Viruses, ICTV (1982). It is found primarily in lilies, although more plants are susceptible, and the virus is thought to be only transmitted mechanically. There are no known vectors; however, the application of insecticides effectively reduced the spread of LVX, from which it may be gathered that the virus’ transmission is insect-mediated. Symptoms of this virus are as of yet unknown, obfuscating the capability to examine the extent of natural infection and spread. Structure LVX is a non-enveloped virus with helical symmetry. All potexviruses, including LVX are believed to have slightly less than 9 protein subunits per helical turn. This pattern of nucleocapsid formation causes the nucleocapsid to be an elongated, flexible, filamentous virus like most plant viruses ...

Alternanthera Mosaic Virus
Alternanthera mosaic virus (AltMV) is a plant pathogenic virus. AltMV belongs to the virus genus '' Potexvirus'' and the virus family ''Alphaflexiviridae''. AltMV was first identified in 1999 in Queensland, Australia. The virus was found in ''Alternanthera pugens'' ''(Amaranthaceae)'', a weed found in both the southern USA and Australia. Since then, AltMV has been identified in various ornamental plants in Italy, the United States (Maryland and Pennsylvania, Florida, and New York), and Brazil. This virus has a close serological relationship (ELISA/antiserum to the capsid protein) with another well known ''Potexvirus'' called '' Papaya mosaic virus'' (PapMV). This relationship has led to several examples of misdiagnosis in the past.Eshenaur, B.C., V.E. Jarlfors, K.A. Kelly and J. O'Mara. 1995.

Cymbidium Mosaic Virus
Cymbidium mosaic virus (CymMV) is a plant pathogenic virus of the family ''Alphaflexiviridae''. Cymbidium mosaic virus and the Odontoglossum ringspot virus (ORSV) are two of the most common viruses affecting cultivated orchids worldwide. Infected plants can have less desirable flowers or other problems, causing significant financial losses to orchid growers. The virus has not often been reported in wild orchid populations. It can be found in a wide variety of orchid genera but does not infect plants other than orchids. Once an orchid is infected, the virus spreads throughout the infected plant in a number of weeks. Control measures may include sanitizing pruning equipment between plants. There is an ELISA test available to test for presence of the virus. It is related to the Narcissus mosaic virus (NMV), the Scallion virus X (SVX), the Pepino mosaic virus (PepMV) and the Potato aucuba mosaic virus (PAMV). Importance Orchids are composed of nearly 200,000 species of pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Bamboo Mosaic Virus
Bamboo mosaic virus (BaMV) is a plant pathogenic virus in the genus ''Potexvirus'' and the family ''Alphaflexiviridae''. BaMV is a filamentous, flexuous rod, 490 nm in length and 15 nm in width. The virus has been fully sequenced and it is 6366 nucleotides long. Like other members of the genus ''Potexvirus'', BaMV is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein. No insect vector is known. However, it is easily mechanically transmitted on contaminated tools used for propagation or harvesting. Distribution It was first isolated in 1974 from two species of bamboo (''Bambusa multiples'' and '' B. vulgaris'') in Brazil. In 1991 it was reported in two other bamboo species (''B. oldhammi'' and ''Dendrocalamus latiflorus'') in Taiwan. Bamboo plants infected with this virus have been found in other Pacific Islands like Hawaii and the Philippines. It has also been found in bamboo plants in Australia. I ...

Papaya Virus X
The papaya (, ), papaw, () or pawpaw () is the plant species ''Carica papaya'', one of the 21 accepted species in the genus ''Carica'' of the family Caricaceae, and also the name of its fruit. It was first domesticated in Mesoamerica, within modern-day southern Mexico and Central America. It is grown in several countries in regions with a tropical climate. In 2022, India produced 38% of the world's supply of papayas. Etymology The word ''papaya'' derives from the Caribbean Taíno "paapaía" and is also the name for the plant. Some etymologists argue that the word comes from the Mayan "páapay-ya", which means "mottled sapote". However, the most commonly accepted etymology is the Taíno one, although it is possible that both word origins are interrelated. The name ''papaw'' or ''pawpaw'' is used alternatively for the fruit only in some regions, that name generally referring to ''Asimina triloba'', an unrelated tree and fruit.

Schlumbergera Virus X
''Schlumbergera'' is a small genus of cacti with six to nine species found in the coastal mountains of south-eastern Brazil. These plants grow on trees or rocks in habitats that are generally shady with high humidity, and can be quite different in appearance from their desert-dwelling cousins. Most species of ''Schlumbergera'' have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti. Common names for these cacti generally refer to their flowering season. In the Northern Hemisphere, they are called Christmas cactus, Thanksgiving cactus, crab cactus and holiday cactus. In Brazil, the genus is referred to as (May flower), reflecting the period in which they flower in the Southern Hemisphere. Most of the popular houseplants are cultivars of ''Schlumbergera'', rather than species, with flowers in white, pink, yellow, orange, red or purple. ...

Alstroemeria Virus X
''Alstroemeria'' (), commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants in the family Alstroemeriaceae. They are all native to South America, although some have become naturalized in the United States, Mexico, Australia, New Zealand, Madeira and the Canary Islands. Almost all of the species are restricted to one of two distinct centers of diversity: one in central Chile and southern Argentina, the other in eastern Brazil. Species of ''Alstroemeria'' from Patagonia are winter-growing plants, while those of Brazil are summer growing. All are long-lived perennials except ''A. graminea'', a diminutive annual from the Atacama Desert of Chile. Description Plants of this genus grow from a cluster of tubers. They send up fertile and sterile stems, the fertile stems of some species reaching in height. The leaves are alternately arranged and resupinate, twisted on the petioles so that the undersides face up. The leaves are variable in shape and th ...
