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. thomasi 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 ''Sanguisorba minor'', the salad burnet, garden burnet, small burnet, burnet (also used for '' Sanguisorba'' generally), pimpernelle, T ...

Pathogen
In biology, a pathogen ( el, πάθος, "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. 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 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 frames, but soil has the ...

Plant Virus
Plant viruses are viruses that 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 higher plants. Most 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 figures relate only to cultivated plants, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 hybrids and cultivars. The most common strawberries grown commercially are cultivars of the 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 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, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits. Etymology The genus name derives from ("strawberry") and , a suffix used to create feminine nouns and plant names. The Latin name is tho ...

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 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. The genome composition of the octoploid strawberry species has generally been indicated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fragaria × Ananassa
The garden strawberry (or simply strawberry; ''Fragaria × ananassa'') is a widely grown hybrid species of the genus '' Fragaria'', collectively known as the strawberries, which are cultivated worldwide for their fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in such prepared foods as jam, juice, pies, ice cream, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in products such as candy, soap, lip gloss, perfume, and many others. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of ''Fragaria virginiana'' from eastern North America and ''Fragaria chiloensis'', which was brought from Chile by Amédée-François Frézier in 1714. Cultivars of ''Fragaria'' × ''ananassa'' have replaced, in commercial production, the woodland strawberry ('' Fragaria vesca''), which was the first stra ...

Rosaceae
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are '' Alchemilla'' (270), '' Sorbus'' (260), '' Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and '' Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Citrus Aurantium
Bitter orange, Seville orange, bigarade orange, or marmalade orange is the citrus tree ''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 probably a cross between the pomelo, ''Citrus maxima'', and the mandarin orange, ''Citrus reticulata''. History Wild trees are found near small streams in generally secluded and wooded parts of Florida and the Bahamas after it was introduced to the area from Spain, where it had been introduced and cultivated heavily beginning in the 10th century by the Moors. Identification Citrus × aurantium can be identified through its orange fruit with a distinctly bitter or sour taste. The tree has alternate simple leaves and thorns on its petiole. Usage Many varieties of bitter orange are used for their essential oil, and are found in perfume, used as a flavoring or as a solvent, and also for consumption. The Seville orange variety is used in the production of marma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duchesnea Indica
''Potentilla indica'' known commonly as mock strawberry, Indian-strawberry, or false strawberry, often referred to as a backyard strawberry, mainly in North America, is a flowering plant in the family Rosaceae. It has foliage and an aggregate accessory fruit similar to that of a true strawberry. It has yellow flowers, unlike the white or slightly pink flowers of true strawberries. It is native to eastern and southern Asia, but has been introduced to many other areas as a medicinal and an ornamental plant, subsequently naturalizing in many regions worldwide. 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 leaves are trifoliate, roughly veined beneath, dark green, and often persisting through the winter, arising from short crowns. The plant spreads along creeping stolons, ...
