Tomato Ringspot Virus
Tomato ringspot virus (ToRSV) is a plant pathogenic virus of the family '' Secoviridae''. It affects species of cucumber, tobacco, tomato, cowpea, among others. It causes ringspots in tobacco plants and raspberries, yellow bud mosaic in peaches, yellow vein in grapes, and stunted growth in ''gladiolus'' and '' Narcissus''. Its range is in the temperate regions of North America, especially where its vector Vector most often refers to: * Euclidean vector, a quantity with a magnitude and a direction * Disease vector, an agent that carries and transmits an infectious pathogen into another living organism Vector may also refer to: Mathematics a ..., '' Xiphinema americanum'' is present. Along with the adult and larval stages of this nematode, the virus is also spread by seed. This type of infection is more common in strawberries and soybeans than any other susceptible plant.

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 ...

Gladiolus
''Gladiolus'' (from Latin, the diminutive of ''gladius'', a sword) is a genus of perennial cormous flowering plants in the iris family (Iridaceae). It is sometimes called the 'sword lily', but is usually called by its generic name (plural ''gladioli''). The genus occurs in Asia, Mediterranean Europe, South Africa, and tropical Africa. The center of diversity is in the Cape Floristic Region.Goldblatt, P. &, J.C. Manning. ''Gladiolus'' in Southern Africa : Systematics, Biology, and Evolution. Fernwood Press, Cape Town; 1998. The genera ''Acidanthera'', ''Anomalesia'', ''Homoglossum'', and ''Oenostachys'', formerly considered distinct, are now included in ''Gladiolus''. Description Gladioli grow from round, symmetrical corms (similar to crocuses) that are enveloped in several layers of brownish, fibrous tunics. Their stems are generally unbranched, producing 1 to 9 narrow, sword-shaped, longitudinal grooved leaves, enclosed in a sheath. The lowest leaf is shortened to a catap ...

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 ...

Vector (epidemiology)
In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. Agents regarded as vectors are mostly blood-sucking (Hematophagy, hematophagous) arthropods such as mosquitoes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected the stomach tissue of a mosquito. Arthropods Arthropods form a major group of pathogen vectors with mosquitoes, Fly, flies, Sandfly, sand flies, lice, fleas, ticks, and mites transmitting a huge number of pathogens. Many such vectors are haematophagous, which feed on blood at some or all stages of their lives. When the insects and ticks feed on blood, the pathogen enters the blood stream of the host. This can happen in different ways. The ''Anopheles'' mosquito, a vector for malaria, filariasis, and various arthropod-borne-viruses (arboviruses), inserts its delicate mouthpart under ...

Xiphinema Americanum
''Xiphinema americanum'', the American dagger nematode, is a species of plant pathogenic nematodes. It is one of many species that belongs to the genus '' Xiphinema''. It was first described by N. A. Cobb in 1913, who found it on both sides of the United States on the roots of grass, corn, and citrus trees.Cobb, N. A. (1913). "New nematode genera found inhabiting freshwater and non-brackish soils.". J. Wash. Acad. Sci. 3: 432–435.4 Not only is ''Xiphinema americanum'' known to vector plant viruses, but also ''X. americanum'' has been referred to as "the most destructive plant parasitic nematode in America", and one of the four major nematode pests in the Southeastern United States.Christie, J. R. (1952). "Some new nematodes of critical importance to Florida growers.". ''Proc. Soil Sci. Soc. Fla.'' 30: 39Thorne, G. (1961). ''Principles of Nematology''. McGraw-Hill.

Stone Fruit Tree Diseases
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing rocks. M ...
