Strawberry Mild Yellow Edge Virus
Strawberry mild yellow-edge virus (SMYEV) is a pathogenic plant virus. Transmission The virus is transmitted by aphid species in the genus '' Chaetosiphon'', mainly '' C. fragaefolii'', '' C. thomasi'', ''C. jacobi''. The virus cannot be transmitted through seeds, contact, grafting, or pollen. It is also a vector for the strawberry yellow edge-associated potexvirus. Host and symptoms Symptoms of this virus mainly include cupped leaflets and reduced in Fragaria species. In some plants such as Fragaria chiloensis and Fragaria × ananassa infection appears symptomless. Susceptible hosts The susceptible host species are mainly in the families Rosaceae and Rutaceae. * Citrus aurantium * '' Duchesnea indica'' * ''Fragaria chiloensis'' * ''Fragaria vesca'' * ''Fragaria virginiana'' * ''Fragaria × ananassa'' * ''Sanguisorba minor'' See also * List of strawberry diseases This article is a list of diseases of strawberry (''Fragaria × ananassa'').

Pathogen
In biology, a pathogen (, "suffering", "passion" and , "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a Germ theory of disease, germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or Transmission (medicine), transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time ...

Plant Virus
Plant viruses are viruses that have the potential to affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses can be pathogenic to vascular plants ("higher plants"). Many plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. They rarely have an envelope. The great majority have an RNA genome, which is usually small and single stranded (ss), but some viruses have double-stranded (ds) RNA, ssDNA or dsDNA genomes. Although plant viruses are not as well understood as their animal counterparts, one plant virus has become very recognizable: '' tobacco mosaic virus'' (TMV), the first virus to be discovered. This and other viruses cause an estimated US$60 billion loss in crop yields worldwide each year. Plant viruses are grouped into 73 genera and 49 families. However, these fi ...

Fragaria
''Fragaria'' () is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many Hybrid plant, hybrids and cultivars. The most common strawberries grown commercially are cultivars of the strawberry, garden strawberry, a hybrid known as ''Fragaria'' × ''ananassa''. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world. Description Strawberries are not Berry (botany), berries in the botanical sense.Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. The fleshy and edible part of the "fruit" is a receptacle (botany), receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits.

Fragaria Chiloensis
''Fragaria chiloensis'', the beach strawberry, Chilean strawberry, or coastal strawberry, is one of two species of wild strawberry that were hybridized to create the modern garden strawberry (''F. × ananassa''). It is native to the Pacific Ocean coasts of North and South America. Description It is an evergreen plant growing to 15–30 centimetres (6–12 inches) tall. The relatively thick leaves are glossy green and trifoliate, each leaflet around 5 cm (2 in) long. The stems are covered with long hairs and the leaves sometimes have a dense fringe of hairs. The flowers are white, produced in spring and early summer. The fruit, a strawberry, is edible, red on the surface and white inside. Genetics All strawberries have a base haploid count of 7 chromosomes. ''F. chiloensis'' is octoploid, having eight sets of these chromosomes for a total of 56. These eight genomes pair as four distinct sets, of two different types, with little or no pairing between sets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fragaria × Ananassa
The garden strawberry (or simply strawberry; ''Fragaria × ananassa'') is a widely grown hybrid plant cultivated worldwide for its fruit. The genus ''Fragaria'', the strawberries, is in the rose family, Rosaceae. The fruit is appreciated for its aroma, bright red colour, juicy texture, and sweetness. It is eaten either fresh or in prepared foods such as jam, ice cream, and chocolates. Artificial strawberry flavourings and aromas are widely used in commercial products. Botanically, the strawberry is not a berry, but an aggregate accessory fruit. Each apparent 'seed' on the outside of the strawberry is actually an achene, a botanical fruit with a seed inside it. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of '' F. virginiana'' from eastern North America and '' F. chiloensis'', which was brought from Chile by Amédée-François Frézier in 1714. Cultivars of ''F.'' × ''ananassa'' have replaced the woodland strawberry '' F. vesca'' in co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family are '' Alchemilla'' (270), '' Sorbus'' (260), ''Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds.

Citrus Aurantium
The bitter orange, sour orange, Seville orange, bigarade orange, or marmalade orange is the hybrid citrus tree species ''Citrus'' × ''aurantium'', and its fruit. It is native to Southeast Asia and has been spread by humans to many parts of the world. It is a cross between the pomelo, ''Citrus maxima'', and the wild type mandarin orange, ''Citrus reticulata''. The bitter orange is used to make essential oil, used in foods, drinks, and pharmaceuticals. The Seville orange is prized for making British orange marmalade. Definition In some proposed systems, the species ''Citrus'' × ''aurantium'' includes not only the bitter orange proper, but all other Hybrid (biology), hybrids between the pomelo and the wild type mandarin orange, mandarin, namely the sweet orange, the grapefruit, and all cultivated mandarin orange, mandarins. p. 69–70 This article only deals with the bitter orange proper.

Duchesnea Indica
''Potentilla indica'', known commonly as mock strawberry, Indian strawberry, or snakeberry in North America, is a flowering plant in the family Rosaceae. It has ternate foliage and an aggregate accessory fruit, similar to true strawberries of the genus ''Fragaria''. Unlike the white or slightly pink flowers of true strawberries, ''Potentilla indica'' has yellow flowers, as do many other Potentilla species. It is native to eastern and southern Asia, but has naturalized in many regions worldwide. They are considered to be an invasive species and weed by some. Many sources consider this plant part of the genus ''Potentilla'' due to evidence from chloroplast genetic sequence data that the genus ''Duchesnea'' is included within ''Potentilla'', though some still list it as ''Duchesnea indica''. Description The herbaceous plant spreads along creeping stolons, rooting and producing plantlets at each node. The leaves are trifoliate, dark green, and somewhat thick. The flowers are produc ...
