Raspberry Ringspot Virus

	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 79 accepted species of vining plants in the flowering plant family Vitaceae. The genus is made up of species predominantly from the Northern Hemisphere. It is economically important as the source of grapes, ... 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 in the order ''Picornavirales''. Plants serve as natural hosts. There are 8 genera and 86 species in this family, one of which is unassigned to a genus. 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 ''Comovirinae'' is a subfamily of viruses in the order ''Picornavirales'', in the family ''Secoviridae''; its genera were formerly classified in the family ''Comoviridae''.

picture info	Vitis ''Vitis'' (grapevine) is a genus of 79 accepted species of vining plants in the flowering plant family Vitaceae. The genus is made up 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 dieceous. 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 berrie ...

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, ''N. pseudonarcissus''. narcissus, and jonquil are used to describe all or some 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. ''Narcissus'' were well known in ancient civilisation, both medicinally and botanically, but formally described by Carl Linnaeus, Linnaeus in his ''Species Plantarum'' (1753). The genus ...

picture info	Raspberry Diseases The raspberry is the edible fruit of a multitude of plant species in the genus ''Rubus'' of the rose family, most of which are in the subgenus '' Idaeobatus''. The name also applies to these plants themselves. Raspberries are perennial with woody stems. World production of raspberries in 2020 was 895,771 tonnes, led by Russia with 20% of the total. Description A raspberry is an aggregate fruit, developing from the numerous distinct carpels of a single flower. What distinguishes the raspberry from its blackberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) the fruit. When picking a blackberry fruit, the torus stays with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit. Raspberries are grown for the fresh fruit market and for commercial processing into individually quick frozen (IQF) fruit, purée, juice, or as dried fruit used in a variety of grocery products such as ras ...
