Émile Blanchard
Charles Émile Blanchard (6 March 1819 – 11 February 1900) was a French zoologist and entomologist. Career Blanchard was born in Paris. His father was an artist and naturalist and Émile began natural history very early in life. When he was 14 years old, Jean Victoire Audouin (1797—1841), allowed him access to the laboratory of the Muséum national d'Histoire naturelle. In 1838, he became a technician or ''préparateu''r in this then, as now, famous institution. In 1841, he became assistant-naturalist. He accompanied Henri Milne-Edwards (1800—1885) and Jean Louis Armand de Quatrefages de Breau (1810—1892) to Sicily on a marine zoology expedition. He published, in 1845 a ''Histoire des insectes'', or History of the insects and, in 1854—1856 ''Zoologie agricole'' or Agricultural Zoology. This last work is remarkable: it presents in a precise way the harmful or pest species and the damage they cause to various crop plants. This work was illustrated by his father. Bl ...

Brassica Oleracea
''Brassica oleracea'' is a plant species from family Brassicaceae that includes many common cultivars used as vegetables, such as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, Savoy cabbage, kohlrabi, and gai lan. Its uncultivated form, wild cabbage, native to coastal southern and western Europe, is a hardy plant with high tolerance for salt and lime. However, its intolerance of competition from other plants typically restrict its natural occurrence to limestone sea cliffs, like the chalk cliffs on both sides of the English Channel. Wild ''B. oleracea'' is a tall biennial plant that forms a stout rosette of large leaves in the first year. The leaves are fleshier and thicker than other ''Brassica'' species—an adaptation that helps it store water and nutrients in its difficult growing environment. In its second year, it uses the stored nutrients to produce a flower spike tall with numerous yellow flowers. A 2021 study suggested that the Eastern Medite ...

Glycine Max
Glycine (symbol Gly or G; ) is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable), with the chemical formula NH2‐ CH2‐ COOH. Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG). Glycine is integral to the formation of alpha-helices in secondary protein structure due to its compact form. For the same reason, it is the most abundant amino acid in collagen triple-helices. Glycine is also an inhibitory neurotransmitter – interference with its release within the spinal cord (such as during a ''Clostridium tetani'' infection) can cause spastic paralysis due to uninhibited muscle contraction. It is the only achiral proteinogenic amino acid. It can fit into hydrophilic or hydrophobic environments, due to its minimal side chain of only one hydrogen atom. History and etymology Glycine was discovered in 1820 by the French chemist Henri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorghum Bicolor
''Sorghum bicolor'', commonly called sorghum () and also known as great millet, broomcorn, guinea corn, durra, imphee, jowar, or milo, is a Poaceae, grass species cultivated for its grain, which is used for food for humans, animal feed, and ethanol production. Sorghum originated in Africa, and is now cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth-most important cereal crop after rice, wheat, maize, and barley, with 59.34 million metric tons of annual global production in 2018. ''S. bicolor'' is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 2 to 4 mm in diameter. Sweet sorghums are sorghum cultivars that are primarily grown for forage, syrup production, and ethanol; they are taller than those grown for grain. ''Sorghum bicolor'' is the cultivated species of sorghum; its wild relatives make up the botanical genus ''Sorghum''. History The first archae ...

Secale Cereale
Rye (''Secale cereale'') is a grass grown extensively as a grain, a cover crop and a forage crop. It is a member of the wheat tribe (Triticeae) and is closely related to both wheat (''Triticum'') and barley (genus ''Hordeum''). Rye grain is used for flour, bread, beer, crispbread, some whiskeys, some vodkas, and animal fodder. It can also be eaten whole, either as boiled rye berries or by being rolled, similar to rolled oats. Rye is a cereal grain and should not be confused with ryegrass, which is used for lawns, pasture, and as hay for livestock. Distribution and habitat Rye is one of a number of species that grow wild in the Levant, central and eastern Turkey and in adjacent areas. Evidence uncovered at the Epipalaeolithic site of Tell Abu Hureyra in the Euphrates valley of northern Syria suggests that rye was among the first cereal crops to be systematically cultivated, around 13,000 years ago. However, that claim remains controversial; critics point to inconsistencie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oryza Sativa
''Oryza sativa'', commonly known as Asian rice or indica rice, is the plant species most commonly referred to in English as ''rice''. It is the type of farmed rice whose cultivars are most common globally, and was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago. ''Oryza sativa'' belongs to the genus '' Oryza'' of the grass family Poaceae. With a genome consisting of 430 Mbp across 12 chromosomes, it is renowned for being easy to genetically modify and is a model organism for the botany of cereals. Classification ''Oryza sativa'' contains two major subspecies: the sticky, short-grained ''japonica'' or ''sinica'' variety, and the nonsticky, long-grained ' rice variety. ''Japonica'' was domesticated in the Yangtze Valley 9–6,000 years ago, and its varieties can be cultivated in dry fields (it is cultivated mainly submerged in Japan), in temperate East Asia, upland areas of Southeast Asia, and high elevations in South Asia, while ''indica'' w ...

Capsicum Annuum
''Capsicum annuum'' is a species of the plant genus ''Capsicum'' native to southern North America, the Caribbean, and northern South America. This species is the most common and extensively cultivated of the five domesticated capsicums. The species encompasses a wide variety of shapes and sizes of peppers, including sweet bell peppers and some chili pepper varieties such as jalapeños, New Mexico chile, and cayenne peppers. Cultivars descended from the wild American bird pepper are still found in warmer regions of the Americas. In the past, some woody forms of this species have been called '' C. frutescens'', but the features that were used to distinguish those forms appear in many populations of ''C. annuum'' and are not consistently recognizable features in ''C. frutescens'' species. Characteristics Although the species name ''annuum'' means 'annual' (from the Latin ''annus'' "year"), the plant is not an annual but is frost tender. In the absence of winter frosts it can survive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachis Hypogaea
The peanut (''Arachis hypogaea''), also known as the groundnut, goober (US), pindar (US) or monkey nut (UK), is a legume A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock f ... crop grown mainly for its edible Seed, seeds. It is widely grown in the tropics and subtropics, important to both small and large commercial producers. It is classified as both a grain legume and, due to its high oil content, an oil crop. World annual production of shelled peanuts was 44 million tonnes in 2016, led by China with 38% of the world total. Atypically among legume crop plants, peanut pods develop underground (geocarpy) rather than above ground. With this characteristic in mind, the botanist Carl Linnaeus gave peanuts the specific epithet ''hypogaea'', which means "under the earth." The peanut bel ...

Pisum Sativum
The pea is most commonly the small spherical seed or the seed-pod of the flowering plant species ''Pisum sativum''. Each pod contains several peas, which can be green or yellow. Botanically, pea pods are fruit, since they contain seeds and develop from the ovary of a (pea) flower. The name is also used to describe other edible seeds from the Fabaceae such as the pigeon pea (''Cajanus cajan''), the cowpea (''Vigna unguiculata''), and the seeds from several species of ''Lathyrus''. Peas are annual plants, with a biological life cycle, life cycle of one year. They are a cool-season crop grown in many parts of the world; planting can take place from winter to early summer depending on location. The average pea weighs between 0.1 and 0.36 gram. The immature peas (and in snow peas the tender pod as well) are used as a vegetable, fresh, frozen or canned; varieties of the species typically called field peas are grown to produce dry peas like the split pea shelled from a matured ...

Avena Sativa
The oat (''Avena sativa''), sometimes called the common oat, is a species of cereal grain grown for its seed, which is known by the same name (usually in the plural, unlike other cereals and pseudocereals). While oats are suitable for human consumption as oatmeal and rolled oats, one of the most common uses is as livestock feed. Oats are a nutrient-rich food associated with lower blood cholesterol when consumed regularly. Avenins are oat gluten proteins, similar to gliadin in wheat. They can trigger celiac disease in a small proportion of people. Also, oat products are frequently contaminated by other gluten-containing grains, mainly wheat and barley. Origin The wild ancestor of ''Avena sativa'' and the closely related minor crop '' A. byzantina'' is '' A. sterilis''. ''A. sterilis'' is a wild oat that is naturally hexaploid. Genetic evidence shows the ancestral forms of ''A. sterilis'' grew in the Fertile Crescent of the Near East. Oats are usually thought to have emerged a ...

Phaseolus Lunatus
A lima bean (''Phaseolus lunatus''), also commonly known as the butter bean, sieva bean, double bean, Madagascar bean, or wax bean is a legume grown for its edible seeds or beans. Origin and uses ''Phaseolus lunatus'' is found in Meso- and South America. Two gene pools of cultivated lima beans point to independent domestication events. The Mesoamerican lima bean is distributed in neotropical lowlands, while the other is found in the western Andes. They were discovered in Peru and may have been the first plant that was brought up under civilization by the native farmers. The Andes domestication took place around 2000 BC and produced a large-seeded variety (lima type), while the second, taking place in Mesoamerica around 800 AD, produced a small-seeded variety (Sieva type). By around 1300, cultivation had spread north of the Rio Grande, and, in the 1500s, the plant began to be cultivated in the Old World. The small-seeded (Sieva) type is found distributed from Mexico to Argent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vigna Unguiculata
The cowpea (''Vigna unguiculata'') is an annual herbaceous legume from the genus ''Vigna''. Its tolerance for sandy soil and low rainfall have made it an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name. Four subspecies of cowpeas are recognised, of which three are cultivated. A high level of morphological diversity is found within the species with large variations in the size, shape, and structure of the plant. Cowpeas can be erect, semierect ( trailing), or climbing. The crop is mainly grown for its seeds, which are high in protein, although the leaves and immature seed pods can also be consumed. Cowpeas were domesticated in Africa and are one of the oldest crop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
