The peanut, also known as the groundnut, goober (US), pindar (US) or monkey nut (UK), is a legume crop grown mainly for its edible 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".
Arachis is a genus of about 70 species of annual and perennial flowering plants in the family (Fabaceae), native to South America, and was recently assigned to the informal monophyletic Pterocarpus clade of the Dalbergieae. At least one species, the peanut, is a major food crop species of global importance; some of the other species are cultivated for food to a small extent in South America. Other species such as A. pintoi are cultivated worldwide as forage and soil conditioner plants, with the leaves providing high-protein feed for grazing livestock and a nitrogen source in agroforestry and permaculture systems.
Arachis ipaensis is a herb in the Faboideae subfamily. This plant is cited as gene sources for research in plant biology of peanut. Its genome has been sequenced.
Arachis batizocoi is a herb native to Bolivia and Paraguay. This plant is cited as gene sources for research in plant biology of peanut. Arachis batizocoi maintains a divergent genome as well as high fertility that facilitates the upbringing of new and beneficial alleles within peanut crops. Such high crossability has increased the frequency of several advantageous alleles that have improved plant life and agricultural output. Among these are boosted resistance against groundnut yield-limiting diseases such as late leaf spot (LLS) and groundnut rosette disease (GRD), larger seeds, and a higher overall yield.
Arachis cardenasii is a herb in the Fabaceae family. This plant is cited as gene sources for research in plant biology of peanut ; for example, Cercospora leaf spot resistance.
Arachis villosulicarpa is a perennial peanut species, which is cultivated by indigenous people in Mato Grosso, a state of Brazil. Its wild progenitor is thought to be Arachis pietrarellii. Although it is related to the common peanut, Arachis hypogaea, it was separately domesticated: A. villosulicarpa is diploid, whereas A. hypogaea is tetraploid.
In biology, the BBCH-scale for cotton describes the phenological development of cotton plants Gossypium hirsutum using the BBCH-scale.
In biology, the BBCH-scale for peanut describes the phenological development of peanuts using the BBCH-scale.
Cercospora arachidicola is a fungal ascomycete plant pathogen that causes early leaf spot of peanut. Peanuts originated in South America and are cultivated globally in warm, temperate and tropical regions.
Sphaceloma arachidis is a plant pathogen infecting peanuts.
Peanut agglutinin (PNA) is plant lectin protein derived from the fruits of Arachis hypogaea. Peanut agglutinin may also be referred to as Arachis hypogaea lectin. Lectins recognise and bind particular sugar sequences in carbohydrates; peanut agglutinin binds the carbohydrate sequence Gal-β(1-3)-GalNAc. The name "peanut agglutinin" originates from its ability to stick together (agglutinate) cells, such as neuraminidase-treated erythrocytes, which have glycoproteins or glycolipids on their surface which include the Gal-β(1-3)-GalNAc carbohydrate sequence.
A crop wild relative (CWR) is a wild plant closely related to a domesticated plant. It may be a wild ancestor of the domesticated (cultivated) plant or another closely related taxon.
The Legume Information System (LIS) is legume sciences portal specifically for legume breeders and researchers, established and supported by the Agricultural Research Service of the United States Department of Agriculture. The mission of the Legume Information System is "to facilitate discoveries and crop improvement in the legumes," in particular to improve crop yields, their nutritional value, and our understanding of basic legume science.
Ara h 1 is a seed storage protein from Arachis hypogaea (peanuts). It is a heat stable 7S vicilin-like globulin with a stable trimeric form that comprises 12-16% of the total protein in peanut extracts. Ara h 1 is known because sensitization to it was found in 95% of peanut-allergic patients from North America. In spite of this high percentage, peanut-allergic patients of European populations have fewer sensitizations to Ara h 1.
Joseph ("Joe") Smartt, was a British geneticist with major contributions to the knowledge of crop evolution, especially of grain legumes.
Chryseobacterium arachidiradicis is a Gram-negative and rod-shaped bacteria from the genus Chryseobacterium which has been isolated from soil around a peanut in Alabama in the United States.
Bradyrhizobium guangdongense is a bacterium from the genus of Bradyrhizobium which has been isolated from the effective nodules of a peanut plant.
Brigida Antónia Correia is a politician from East Timor. She has been a member of the National Congress for Timorese Reconstruction (CNRT) party since 2007. Priot to that, she had been a member of the Partido Trabalhista since 2000.
Thecaphora frezzii, commonly referred to as peanut smut, is a species of smut fungus of the genus Thecaphora and the family Glomosporiaceae. It is a basidiomycete fungus that infects peanut plants. It is currently only found in South America, more specifically in Argentinian peanut farms.
