Canna Virus
The genus '' Canna'' is susceptible to certain plant viruses, which may result in spotted or streaked leaves, in a mild form, but can finally result in stunted growth and twisted and distorted blooms and foliage. Known species of virus are: * Canna yellow mottle badnavirus (CYMV) infecting ''canna'' species. * Bean yellow mosaic virus (BYMV) infecting cannas, gladiolus, freesia and many legumes. * Tomato aspermy virus (TAV), causes mosaic in cannas, but it has not been reported affecting cannas in the UK. * Cucumber mosaic virus (CMV), cannas are susceptible to this virus, but none found yet in England. * Canna yellow streak virus (CaYSV), recently discovered by scientists at the Central Science Laboratory in England. Dr Rick Mumford, senior virologist at CSL is quoted as stating "Typical virus symptoms include flecking, mosaic, leaf streaking and necrosis, which in severe cases render plants unsaleable." The reference to this quoted article is shown below. Known facts Overall, ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canna (plant)
''Canna'' or canna lily is the only genus of flowering plants in the family Cannaceae, consisting of 10 species.The Cannaceae of the World, H. Maas-van der Kamer & P.J.M. Maas, BLUMEA 53: 247-318 Cannas are not true lilies, but have been assigned by the APG II system of 2003 to the order Zingiberales in the monocot clade Commelinids, together with their closest relatives, the gingers, spiral gingers, bananas, arrowroots, heliconias, and birds of paradise. The plants have large foliage, so horticulturists have developed selected forms as large-flowered garden plants. Cannas are also used in agriculture as a source of starch for human and animal consumption. Khoshoo, T.N. & Guha, I. - Origin and Evolution of Cultivated Cannas. Vikas Publishing House Although plants of the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries of the world, as long as they receive at least 6–8 hours average sunlight during the summer, and ar ...

Virus
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisting of (i) the genetic material, i. ...

Bean Yellow Mosaic Virus
''Bean yellow mosaic virus'' is a plant pathogenic virus in the genus ''Potyvirus'' and the virus family ''Potyviridae''. Like other members of the Potyvirus genus, it is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein. The virus is a filamentous particle that measures about 750 nm in length. This virus is transmitted by species of aphids and by mechanical inoculation. Geographic distribution and host range A mosaic disease, believed to be bean yellow mosaic virus, was first reported in the early 1900s infecting garden peas (''Pisum sativum'') in the Northeastern United States. The virus is currently believed to be distributed worldwide. In addition to peas, this virus is known to infect many other legumes (family Fabaceae) including green beans (''Phaseolus vulgaris''), peanuts (''Arachis hypogaea''), soybeans (''Glycine max''), Faba beans (''Vicia faba''), several species of clover (''Trifolium hy ...

Cucumber Mosaic Virus
''Cucumber mosaic virus'' (CMV) is a plant pathogenic virus in the family ''Bromoviridae''. This virus has a worldwide distribution and a very wide host range, having the reputation of the widest host range of any known plant virus. It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion. It can also be transmitted in seeds and by the parasitic weeds, ''Cuscuta sp.'' (dodder). Hosts and symptoms This virus was first characterized in cucumbers (''Cucumis sativus'') showing mosaic symptoms in 1934, hence the name ''Cucumber mosaic''. Since then, it has been found to infect a great variety of other plants. These include other vegetables such as squash, melons, peppers, eggplants,tomatoes, beans, carrots, celery, lettuce, spinach, beets, many ornamentals and bedding plants, such as '' Narcissus'', and various weeds. Its presence has been confirmed on every continent of the world, including Antarctica. Symptoms seen with this virus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banana Streak Virus
Banana streak virus (BSV) is a name given to various plant viruses in the genus ''Badnavirus''. Banana streak was first identified in 1958 in Côte d’Ivoire and is now in many countries in the tropics. The primary symptoms of disease are chlorotic streaks on the banana leaves and splitting of their pseudostem. In later stages of the disease, these streaks may become necrotic, and the heart of the pseudostem may rot, ultimately leading to death of the plant. Although not necessary to complete the life cycle, members of ''Caulimoviridae'' (as well as ''Geminiviridae'') have been shown to integrate into their host genomes. When the host is stressed, the integrated genome of BSV may be able to recombine out into its episomal form, though the mechanism is not well understood. While there are several copies of BSV in ''Musa Musa may refer to: Places * Mūša, a river in Lithuania and Latvia * Musa, Azerbaijan, a village in Yardymli Rayon * Musa, Iran, a village in Ilam Province * ...

List Of Canna Species
''Canna (plant), Canna'' species have been categorised by two different taxonomists in the course of the last three decades. They are Paulus Johannes Maria Maas, Paul Maas, from the Netherlands and Nobuyuki Tanaka from Japan.Tanaka, N. (2001) Taxonomic revision of the family Cannaceae in the New World and Asia. Both reduced the number of species from the 50-100 that had been accepted previously, and assigned most to being synonym (taxonomy), synonyms. Inevitably, there are some differences in their categorisations, and the individual articles on the species describe the differences. The reduction in the number of species is also confirmed by work done by Kress and Prince at the Smithsonian Institution, however, this only covers a subset of the species range.Prince, Linda M.* and W. John Kress. Smithsonian Institution Tanaka's 2001 ''Taxonomic revision of the family Cannaceae in the New World and Asia'' is one source of species names, allied with the proposal to conserve the name ...

List Of Canna Cultivars This list of ''Canna'' cultivars is a gallery of named cultivars of plants in the genus '' Canna'' that are representative of the various ''Canna'' cultivar groups (i.e., groups of very similar cultivars). Names of cultivars conform to the rules of the International Society for Horticultural Science (ISHS) Commission for Nomenclature and Cultivar Registration, as laid down in the International Code of Nomenclature for Cultivated Plants. They are registered with an International Cultivar Registration Authority (ICRA), which for the genus ''Canna'' is the Royal General Bulbgrowers' Association of the Netherlands (KAVB). Foliage group Cultivars, F1 and F2 hybrids, normally with small species-like flowers, but grown principally for their foliage. This group has occasionally been referred to as the Année Group, after the originator, Théodore Année, the world's first ''Canna'' hybridizer. However, the use of an accented character in the name creates problems, both in pronunciatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
