The botanical name for groundnut, Arachis hypogaea Linn., is derived from two Greek words, Arachis meaning a legume and hypogaea meaning below ground, referring to the formation of pods in the soil. Peanuts originally came to Indonesia from the Philippines, where the legume derived from Mexico in times of Spanish colonization. [16] After fertilization, a short stalk at the base of the ovary (termed a pedicel) elongates to form a thread-like structure known as a "peg". For more examples of chromosome band numbers, see the chromosome ideograms accessible from: GeneMap'99 (click on a chromosome number). [53][54], A common cooking and salad oil, peanut oil is 46% monounsaturated fats (primarily oleic acid), 32% polyunsaturated fats (primarily linoleic acid), and 17% saturated fats (primarily palmitic acid). [1] Like most other legumes, peanuts harbor symbiotic nitrogen-fixing bacteria in their root nodules.[6]. The small Spanish types are grown in South Africa, and in the southwestern and southeastern United States. [8][9], The process of domestication through artificial selection made A. hypogaea dramatically different from its wild relatives. Also, in the Peruvian city of Arequipa, a dish called ocopa consists of a smooth sauce of roasted peanuts and hot peppers (both native to the region) with roasted onions, garlic, and oil, poured over meat or potatoes. Bamba puffs are a popular snack in Israel. The groundnut, or peanut, is not a nut, but a legume. For 160 families, inferred ancestral n are provided for the first time.

Subspecies A. h. fastigiata types are more upright in their growth habit and have shorter crop cycles. For Peanut allergen powder, see, "Goober peas" redirects here. This explains their name. Peanut plants continue to produce flowers when pods are developing; therefore even when they are ready for harvest, some pods are immature. The leaves are opposite and pinnate with four leaflets (two opposite pairs; no terminal leaflet); each leaflet is 1 to 7 centimetres (1⁄2 to 2 3⁄4 in) long and 1 to 3 cm (1⁄2 to 1 1⁄4 in) across. Peanuts have a variety of industrial end uses. One of the presumed causes is that such morphologically normal embryos have an abnormal number of chromosomes (aneuploidies). These flowers self-pollinate and produce an anchor or peg which penetrates the ground. Throughout the region, many candies and snacks are made using peanuts. [26], Peanut oil is often used in cooking, because it has a mild flavor and a relatively high smoke point. Sometimes known also as Texas Red or White, the plants are similar to Valencia types, except the stems are green to greenish brown, and the pods are rough, irregular, and have a smaller proportion of kernels. It is classified as both a grain legume and, due to its high oil content, an oil crop. Peanut forage. Paint, varnish, lubricating oil, leather dressings, furniture polish, insecticides, and nitroglycerin are made from peanut oil. chromosome, chromosome number, 2n= From the website (now inactive) of Dr. Bruce Reid at Kean University: Chromosome Numbers of Selected Organisms. The pods are borne within 5 to 10 cm (2 to 4 in) of the base of the plant. Kovilpatti is known for its sweet peanut chikki or peanut brittle, which is also used in savory and sweet mixtures, such as Bombay mix. Groundnut cake is a livestock feed, mostly used by cattle as protein supplements. Also, the yield of the peanut crop itself is increased in rotations, through reduced diseases, pests and weeds. They also stated, "Refined peanut oil does not seem to pose a risk to most people with peanut allergy." [62], Some school districts in the United States and elsewhere have banned peanuts. There are many peanut cultivars grown around the world. in crosses involving cultivated groundnut and wild species (A. cardenasii). It is also used in a number of confections, such as peanut-flavored granola bars or croissants and other pastries. Apart from N, P and K, other nutrient deficiencies causing significant yield losses are Ca, Fe and B. Biotic stresses mainly include pests, diseases and weeds. Apios americana, sometimes called the potato bean, hopniss, Indian potato, hodoimo, America-hodoimo, cinnamon vine, American groundnut, or groundnut (but not to be confused with other plants sometimes known by the name groundnut) is a perennial vine that bears edible beans and large edible tubers. Today it is an important oilseed and food crop. Another use is peanut oil for cooking. In order to maximize yield, the timing of harvest is important. The protein portion is used in the manufacture of some textile fibers. Indian cuisine uses roasted, crushed peanuts to give a crunchy body to salads; they are added whole (without pods) to leafy vegetable stews for the same reason. Peanuts are also widely used in Southeast Asian cuisine, such as in Malaysia, Vietnam, and Indonesia, where they are typically made into a spicy sauce. [24][self-published source?] In general, all the chromosomes of cultivated groundnut are metacentric ... Chromosome number, morphology and their application to the problem of the origin of the cultivated forms. Molecular breeding approaches, namely, marker assisted breeding and genetic transformation helps to accelerate the breeding programme to develop high yielding cultivars with desirable attributes, through introgression of specific gene(s) identified in land races or compatible diploid wild species. In the United States, the Spanish group is primarily grown in New Mexico, Oklahoma, and Texas.[25]. Because of their widespread use in prepared and packaged foods, the avoidance of peanuts can be difficult. Our analyses revealed an ancestral haploid chromosome number for angiosperms of n = 7, a diploid status, and an ancestral 1C of 1.73 pg. The machine lifts the "bush" from the ground and shakes it, then inverts the bush, leaving the plant upside down on the ground to keep the peanuts out of the soil. In a 100-gram (3 1⁄2-ounce) reference serving, peanuts provide 2,385 kilojoules (570 kilocalories) of food energy and are an excellent source (defined as more than 20% of the Daily Value, DV) of several B vitamins, vitamin E, several dietary minerals, such as manganese (95% DV), magnesium (52% DV) and phosphorus (48% DV), and dietary fiber (right table). Common Indonesian peanut-based dishes include gado-gado, pecel, karedok, and ketoprak, vegetable salads mixed with peanut sauce, and the peanut-based sauce, satay. While descending dysploidy is equally distributed early and late across the phylogeny, polyploidy is … Crunchy coated peanuts, called kabukim in Hebrew, are a popular snack in Israel. Most Indians use mustard, sunflower, and peanut oil for cooking. Harvesting occurs in two stages. Like those of many other legumes, the leaves are nyctinastic; that is, they have "sleep" movements, closing at night. Groundnut (Arachis hypogaea L.), a self-pollinated legume is an important crop cultivated in 24 million ha world over for extraction of edible oil and food uses. With this characteristic in mind, the botanist Carl Linnaeus named the species hypogaea, which means "under the earth". [43], The protein cake (oilcake meal) residue from oil processing is used as an animal feed and as a soil fertilizer. [11][15] They are borne in axillary clusters on the stems above ground, and last for just one day. Main determinant is the karyotype, referring to the number, as well as the size and shape of the chromosomes of an individual. Copyright © 2016 Elsevier Inc. All rights reserved. [67] However, crude (unrefined) peanut oils have been shown to contain protein, which may cause allergic reactions. [37] Peanut butter is a common peanut-based food, representing half of American total peanut consumption and $850 million in annual retail sales. [72], A warning sign for the presence of peanuts and peanut dust, A bowl of sev mamra, consisting of puffed rice, peanuts and fried seasoned noodles, Peanut sweet known as chikki made from peanuts and jaggery, "Arachis hypogaea" redirects here. In the Indian subcontinent, peanuts are a light snack, usually roasted and salted (sometimes with the addition of chilli powder), and often sold roasted in pods or boiled with salt. [36] In the United States, peanuts and peanut butter are central to American dietary practices, and are typically considered as comfort foods. However, they point out that refined peanut oil can still pose a risk to peanut-allergic individuals if oil that has previously been used to cook foods containing peanuts is reused. [15] The United States Department of Agriculture initiated a program to encourage agricultural production and human consumption of peanuts in the late 19th and early 20th centuries. Lower-quality peanuts, particularly where mold is evident, are more likely to be contaminated. Ploidy (/ ˈ p l ɔɪ d i /) is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. The kernels are rich in oil (48–50%) and protein (25–28%), and are source of several vitamins, minerals, antioxidants, biologically active polyphenols, flavonoids, and isoflavones. Chromosome number in wild Arachis. By continuing you agree to the use of cookies. As a legume, the peanut belongs to the botanical family Fabaceae; this is also known as Leguminosae, and commonly known as the bean, or pea, family. [11] and by artificial selection to A. vedant. In fact, until the completion of meiosis I, the chromosome and chromatid numbers remain the same through all stages. Peanut powder is an important ingredient in the spicy coating for kebabs in Nigeria and Ghana. Most of the pods are clustered around the base of the plant, and only a few are found several inches away. 2019-10-31 at 10:35 pm . [15], Peanut is an annual herbaceous plant growing 30 to 50 cm (12 to 20 in) tall. Cytologia, 7 (1936), pp. [50][51] However, the study designs do not allow cause and effect to be inferred. For the folk song, see, Baughman, Todd; Grichar, James; Black, Mark; Woodward, Jason; Porter, Pat; New, Leon; Baumann, Paul; McFarland, Mark ". [27], Peanut butter is a food paste or spread made from ground dry roasted peanuts. 10:71086 10:72876 10:75794 I was wondering if there is an R package (or perhaps one in Bioconductor) that can take these as input values and provide the SNP rs number … Cultivars of Virginia type peanuts include 'NC 7', 'NC 9', 'NC 10C', 'NC-V 11', 'VA 93B', 'NC 12C', 'VA-C 92R', 'Gregory', 'VA 98R', 'Perry', 'Wilson, 'Hull', 'AT VC-2' and' Shulamit'. Option A is the correct answer. Traditionally, peanuts were pulled and inverted by hand. This peg grows down into the soil, and the tip, which contains the ovary, develops into a mature peanut pod. Peanuts are similar in taste and nutritional profile to "tree nuts" such as walnuts and almonds, and, as a culinary nut, are often served in similar ways in Western cuisines. In Asia, it became an agricultural mainstay and this region is now the largest producer in the world. New York: John Wiley & Sons. Successful farmers are those who apply the prescribed management practices throughout the production process. Both descending dysploidy and polyploidy played crucial roles in chromosome number evolution. Other components are crude fiber, crude protein, and fat. Peanuts are used in the Malian meat stew maafe. Thick peanut butter sauces are also made in Uganda to serve with rice and other starchy foods. The several types of peanut oil include aromatic roasted peanut oil, refined peanut oil, extra virgin or cold-pressed peanut oil, and peanut extract. [45] Poor storage of the cake may sometimes result in its contamination by aflatoxin, a naturally occurring mycotoxin that is produced by Aspergillus flavus and Aspergillus parasiticus. Atypically among legume crop plants, peanut pods develop underground (geocarpy) rather than above ground. [30], Peanuts are particularly common in Peruvian and Mexican cuisine, both of which marry indigenous and European ingredients. [11], The oldest known archeological remains of pods have been dated at about 7,600 years old, possibly a wild species that was in cultivation, or A. hypogaea in the early phase of domestication. [17] Adequate levels of phosphorus, potassium, calcium, magnesium, and micronutrients are also necessary for good yields. This plant goes by a lot of names, most of which are not particularly apt. [70] The United States Department of Agriculture tests every truckload of raw peanuts for aflatoxin; any containing aflatoxin levels of more than 15 parts per billion are destroyed. In South India, groundnut chutney is eaten with dosa and idli as breakfast. Peanuts are a common ingredient of several types of relishes (dishes which accompany nshima) eaten in Malawi and in the eastern part of Zambia, and these dishes are common throughout both countries. Mon - Sun : 07:00AM - 07:00PM Many pre-Columbian cultures, such as the Moche, depicted peanuts in their art.
