Oats
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). Oats appear to have been domesticated as a secondary crop, as their seeds resembled those of other cereals closely enough for them to be included by early cultivators. Oats tolerate cold winters less well than cereals such as wheat, barley, and rye, but need less summer heat and more rain, making them important in areas such as Northwest Europe that have cool, wet summers. They can tolerate low-nutrient and acid soils. Oats grow thickly and vigorously, allowing them to outcompete many weeds, and compared to other cereals are relatively free from diseases. Oats are used for human consumption as oatmeal, including as steel cut oats or rolled oats. Global production is dominated by Canada and Russia; global trade is a small part of production, most of the grain being consumed within the producing countries. O ...

Rolled Oats
Rolled oats are a type of lightly processed whole-grain food. They are made from oat groats that have been dehusked and steamed, before being rolled into flat flakes under heavy rollers and then stabilized by being lightly toasted. Thick-rolled oats, or old-fashioned oats, usually remain unbroken during processing. Rolled whole oats, without further processing, can be cooked into a porridge and eaten as oatmeal; when the oats are rolled thinner and steam-cooked more in the factory, these thin-rolled oats often become fragmented but they will later absorb water much more easily and cook faster into a porridge; when processed this way are sometimes marketed as "quick" or "instant" oats. Rolled oats are most often the main ingredient in granola and muesli. They can be further processed into a coarse powder, which breaks down to nearly a liquid consistency when boiled. Cooked oatmeal powder is often used as baby food. Process The oat, like other cereals, has a hard, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oatmeal
Oatmeal is a preparation of oats that have been dehusked, steamed, and flattened, or a coarse flour of hulled oat grains ( groats) that have either been milled (ground), rolled, or steel-cut. Ground oats are also called white oats. Steel-cut oats are known as coarse oatmeal, Irish oatmeal, or pinhead oats. Rolled oats were traditionally thick old-fashioned oats, but they can be made thinner or smaller and may be categorized as quick oatmeal or instant oatmeal depending on the cooking time required, which is determined by the size of the oats and the amount of precooking. Industrial preparation and varieties The oat grains are dehusked by impact, and are then heated and cooled to stabilize the groats, the seed inside the husk. The groats may be milled to produce fine, medium, or coarse oatmeal. Rolled oats are oats that have been steamed, flattened by a "flaking roller", and dried. Old-fashioned rolled oats are made from whole oat groats and may be thick and require lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avena
''Avena'' is a genus of Eurasian and African plants in the grass family. Collectively known as the oats, they include some species which have been cultivated for thousands of years as a food source for humans and livestock. They are widespread throughout Europe, Asia and northwest Africa. Several species have become naturalized in many parts of the world, and are regarded as invasive weeds where they compete with crop production. All oats have edible seeds, though they are small and hard to harvest in most species. Ecology ''Avena'' species, including cultivated oats, are used as food plants by the larvae of some Lepidoptera species, including rustic shoulder-knot and setaceous Hebrew character. For diseases of oats, see List of oat diseases. Species Cultivated oats One species is of major commercial importance as a cereal grain. Four other species are grown as crops of minor or regional importance. * '' Avena sativa'' – the common oat, a cereal crop of global impor ...

Avena Byzantina
''Avena byzantina'', red oats, is a species of cultivated oat in the family ''Poaceae Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivate ...''. It is native to Greece, Turkey, Cyprus, the Transcaucasus, Iran, and Saudi Arabia. Cultivated for thousands of years, it is better suited to warmer conditions than white or common oats ('' Avena sativa''), but is often sown as a notill winter crop. There are 564 landraces and 203 cultivars of red oats listed in the European Plant Genetic Resources Search Catalogue (EURISCO). Approximately 10% of the millions of hectares worldwide under oats are devoted to red oats, principally for fodder.

Cereal
A cereal is a grass cultivated for its edible grain. Cereals are the world's largest crops, and are therefore staple foods. They include rice, wheat, rye, oats, barley, millet, and maize ( Corn). Edible grains from other plant families, such as amaranth, buckwheat and quinoa, are pseudocereals. Most cereals are annuals, producing one crop from each planting, though rice is sometimes grown as a perennial. Winter varieties are hardy enough to be planted in the autumn, becoming dormant in the winter, and harvested in spring or early summer; spring varieties are planted in spring and harvested in late summer. The term cereal is derived from the name of the Roman goddess of grain crops and fertility, Ceres. Cereals were domesticated in the Neolithic around 8,000 years ago. Wheat and barley were domesticated in the Fertile Crescent; rice and some millets were domesticated in East Asia, while sorghum and other millets were domesticated in West Africa. Maize was domesticat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertile Crescent
The Fertile Crescent () is a crescent-shaped region in the Middle East, spanning modern-day Iraq, Israel, Jordan, Lebanon, Palestine, and Syria, together with northern Kuwait, south-eastern Turkey, and western Iran. Some authors also include Cyprus and northern Egypt. The Fertile Crescent is believed to be the first region where agriculture, settled farming emerged as people started the process of clearance and modification of natural vegetation to grow newly domesticated plants as crops. Early human civilizations such as Sumer in Prehistory of Mesopotamia, Mesopotamia flourished as a result. Technological advances in the region include the Origins of agriculture in West Asia, development of agriculture and the use of Irrigation#History, irrigation, of History of writing#Bronze Age writing, writing, the Wheel#History, wheel, and history of glass, glass, most emerging first in Mesopotamia.

Genetic Analysis
Genetic analysis is the overall process of studying and researching in fields of science that involve genetics and molecular biology. There are a number of applications that are developed from this research, and these are also considered parts of the process. The base system of analysis revolves around general genetics. Basic studies include identification of genes and inherited disorders. This research has been conducted for centuries on both a large-scale physical observation basis and on a more microscopic scale. Genetic analysis can be used generally to describe methods both used in and resulting from the sciences of genetics and molecular biology, or to applied research, applications resulting from this research. Genetic analysis may be done to identify genetic/inherited disorders and also to make a differential diagnosis in certain somatic diseases such as cancer. Genetic analyses of cancer include detection of mutations, fusion genes, and DNA copy number changes. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are visible under a light microscope only during the metaphase of cell division, where all chromosomes are aligned in the center of the cell in their condensed form. Before this stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

Hexaploid
Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in pairs of homologous chromosomes. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis; the sporophyte generation is diploid and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avena Sterilis
''Avena sterilis'' (animated oat, sterile oat, wild oat, wild red oat, winter wild oat; syn. ''Avena ludoviciana'' Durieu; ''Avena macrocarpa'' Moench; ''Avena sterilis'' ssp. ''sterilis''; ''Avena sterilis'' ssp. ''ludoviciana'') is a species of grass weed whose seeds are edible. Many common names of this plant refer to the movement of its panicle in the wind. Description Appearance ''Avena sterilis'' is a stout, broad-leaved grass that grows up to tall. At maturity, it has leaf blades that are up to long, and wide. It has an inflorescence that is either an equilateral or a slightly one-sided panicle. The spikelets usually have 3 florets, but can have anywhere from 2 to 5. The spikelets (without awns) are long; the glumes are long. The florets can either be a straw yellow or slightly reddish in colour. Occasionally, there can be reddish hairs at the base of the floret. The lemma is usually long. The florets are elongate and taper at the top. The two florets clo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop Science
Agricultural science (or agriscience for short) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists. History In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulfate) as a fertilizer.John Armstrong, Jesse Buel. ''A Treatise on Agriculture, The Present Condition of the Art Abroad and at Home, and the Theory and Practice of Husbandry. To which is Added, a Dissertation on the Kitchen and Garden.'' 1840. p. 45. In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
