Raspberry Ringspot Virus
Raspberry ringspot virus (RRSV) is a plant pathogenic virus of the family ''Secoviridae''. It was first described by Cadman in 1958. It causes ringspots in raspberries and strawberries and can cause rasp-leaf symptoms in cherry. It also has been found in many other plants including those in the Vitis ''Vitis'' (grapevine) is a genus of 81 accepted species of vining plants in the flowering plant family Vitaceae. The genus consists of species predominantly from the Northern Hemisphere. It is economically important as the source of grapes, bot ... and Narcissus genera. There are many strains of the virus, the most important including the Scottish strain, the English strain, and the Lloyd George yellow blotch strain. The Scottish strain is the type virus. This virus can be transmitted by nematode vectors. The Scottish strain is mostly spread by '' Longidorus elongatus'', and the English strain by '' Longidorus macrosoma''.

Secoviridae
''Secoviridae'' is a family of viruses 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. Viruses are found in almo ... in the order '' Picornavirales''. Plants serve as natural hosts. There are 10 genera in the family, four of which are assigned to a subfamily. The family was created in 2009 with the grouping of families ''Sequiviridae'', now dissolved, and ''Comoviridae'', now subfamily ''Comovirinae'', along with the then unassigned genera ''Cheravirus'', ''Sadwavirus'', and ''Torradovirus''. Taxonomy The family includes the following genera (-''virinae'' denotes subfamily and -''virus'' denotes genus): * '' Comovirinae'' ** '' Comovirus'' ** '' Fabavirus'' ** '' Mersevirus'' ** '' Nepovirus'' * Unassigned to a subfamily: ** '' Cheravirus'' ** '' Sadwavirus'' ** '' Sequivirus'' ** '' Stralarivirus'' *** St ...

Vitis
''Vitis'' (grapevine) is a genus of 81 accepted species of vining plants in the flowering plant family Vitaceae. The genus consists of species predominantly from the Northern Hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine. The study and cultivation of grapevines is called viticulture. Most cultivated ''Vitis'' varieties are wind-pollinated with hermaphroditic flowers containing both male and female reproductive structures, while wild species are dioecious. These flowers are grouped in bunches called inflorescences. In many species, such as ''Vitis vinifera'', each successfully pollinated flower becomes a grape berry with the inflorescence turning into a cluster of grapes. While the flowers of the grapevines are usually very small, the berries are often large and brightly colored with sweet flavors that attract birds and other animals to disperse the seeds contained within the berries ...

Narcissus (plant)
''Narcissus'' is a genus of predominantly spring flowering perennial plant, perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil,The word "daffodil" is also applied to related genera such as ''Sternbergia'', ''Ismene (plant), Ismene'', and ''Fritillaria meleagris''. It has been suggested that the word "Daffodil" be restricted to the wild species of the British Isles, ''Narcissus pseudonarcissus, N. pseudonarcissus''. narcissus (plural narcissi), and jonquil, are used to describe some or all members of the genus. ''Narcissus'' has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped Corona (plant structure), corona. The flowers are generally white and yellow (also orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona. ''Narcissi'' were well known in ancient civilisation, both medicinally and botanically, but were formally described by Carl Linnaeus, Lin ...

Raspberry Diseases
The raspberry is the edible fruit of several plant species in the genus ''Rubus'' of the Rosaceae, rose family, most of which are in the subgenus ''Rubus#Modern classification, Idaeobatus''. The name also applies to these plants themselves. Raspberries are perennial with woody plant, woody stems. World production of raspberries in 2022 was 947,852 tonnes, led by Russia with 22% of the total. Raspberries are cultivated across northern Europe and North America and are consumed in various ways, including as whole fruit and in Fruit preserves, preserves, cakes, ice cream, and liqueurs. Description A raspberry is an aggregate fruit, developing from the numerous distinct carpels of a single flower. Each carpel then grows into individual drupelet, drupelets, which, taken together, form the body of a single raspberry fruit. As with blackberry, blackberries, each drupelet contains a seed. What distinguishes the raspberry from its blackberry relatives is whether or not the torus (rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
