Strawberry Vein Banding Virus
''Strawberry vein banding virus'' (SVBV) is a plant pathogenic virus and a member of the family '' Caulimoviridae''. History Strawberry vein banding virus (SVBV) was first described by Frazier (1955) after differential aphid transmission to susceptible wild strawberries. He described disease symptomatology, identified wild strawberry plants as suitable virus indicators, and demonstrated virus transmission by various aphids, dodder (Cuscuta subinclusa), and grafting. Virus-vector interactions (i.e., specificity of aphid species, acquisition access and retention times, semi-persistent manner of transmission, and transmission efficiency), and the inability to transmit the virus via sap were established by Frazier (1955). Similar studies focusing on aphid vectors of SVBV and symptomatology were used as the basis for naming the virus (Prentice, 1952; Schöniger, 1958; Frazier and Posnette, 1958; Frazier, 1960; Mellor and Forbes, 1960; Miller and Frazier, 1970; Frazier and Converse, ...

Caulimoviridae
''Caulimoviridae'' is a family of viruses infecting plants. There are 94 species in this family, assigned to 11 genera. Viruses belonging to the family ''Caulimoviridae'' are termed double-stranded DNA (dsDNA) reverse-transcribing viruses (or pararetroviruses) i.e. viruses that contain a reverse transcription stage in their replication cycle. This family contains all plant viruses with a dsDNA genome that have a reverse transcribing phase in their lifecycle. Taxonomy The following genera are recognized: *'' Badnavirus'' *'' Caulimovirus'' *'' Cavemovirus'' *'' Dioscovirus'' *'' Petuvirus'' *'' Rosadnavirus'' *'' Ruflodivirus'' *'' Solendovirus'' *'' Soymovirus'' *'' Tungrovirus'' *'' Vaccinivirus'' Virus particle structure All viruses of this family are non-enveloped. Virus particles are either bacilliform or isometric. The type of nucleocapsid incorporated into the virus structure determines the size of the viral particles. Bacilliform particles are approximately 35–50 ... [...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 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 strawbe ...

Fragaria Vesca
''Fragaria vesca'', commonly called the wild strawberry, woodland strawberry, Alpine strawberry, Carpathian strawberry or European strawberry, is a perennial herbaceous plant in the rose family that grows naturally throughout much of the Northern Hemisphere, and that produces edible fruits. The Latin specific epithet ''vesca'' means "thin, feeble". Description Five to eleven soft, hairy white flowers are borne on a green, soft fresh-hairy stalk that usually lifts them above the leaves. The light-green leaves are trifoliate (in threes) with toothed margins. The plant spreads mostly by means of runners ( stolons), but the seeds are viable and establish new populations. Taxonomy Vilmorin-Andrieux (1885) makes a distinction between wild or wood strawberries (''Fragaria vesca'') and alpine strawberries (''Fragaria alpina''), a distinction which is not made by most seed companies or nurseries, which usually sell ''Fragaria vesca'' as "alpine strawberry". Under wild or wood strawb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aphid
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
