Teosinte
''Zea'' is a genus of flowering plants in the grass family. The best-known species is ''Z. mays'' (variously called maize, corn, or Indian corn), one of the most important crops for human societies throughout much of the world. The four wild species are commonly known as teosintes and are native to Mesoamerica. Etymology ''Zea'' is derived from the Greek name () for another cereal grain (possibly spelt).Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 411 Recognized species The five accepted species names in the genus are: ''Zea mays'' is further divided into four subspecies: ''Z. m. huehuetenangensis'', ''Z. m. mexicana'', '' Z. m. parviglumis'' (Balsas teosinte, the ancestor of maize), and ''Z. m. mays''. The first three subspecies are teosintes; the last is maize, or corn, the only domesticated taxon in the genus ''Zea''. The genus is divided into two sections: ''Luxuriantes'', with ''Z. diploperennis'', ''Z. lux ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zea Mays
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Zea Nicaraguensis
''Zea nicaraguensis'' is an annual, true grass species in the genus '' Zea''. It is considered to be phenotypically the most distinctive, as well as the most threatened teosinte. This teosinte thrives in flooded conditions along 200 m of a coastal estuarine river in northwest Nicaragua at the Reserva Natural de Apacunca. Virtually all populations of teosinte are either threatened or endangered with ''Z. nicaraguensis'' being the most endangered, it survives as about 6000 plants in an area of 200 x 150 m. The Mexican and Nicaraguan governments have taken action in recent years to protect wild teosinte populations, using both ''in situ'' and ''ex situ'' conservation methods. Currently, a large amount of scientific interest exists in conferring beneficial teosinte traits, such as insect resistance, perennialism, and flood tolerance, to cultivated maize lines, although this is very difficult due to linked deleterious teosinte traits.

Zea Diploperennis
''Zea diploperennis'', the diploperennial teosinte, is a species of grass (family: Poaceae) in the genus '' Zea'' and a teosinte (wild relative of maize or corn). It is perennial. Conservation Virtually all populations of this teosinte are either threatened or endangered: ''Z. diploperennis'' exists in an area of only a few square miles.

Currently, a large amount of scientific interest exists in conferring beneficial teosinte traits, such as insect resistance, perennialism, and flood tolerance, to cultivated maize lines, although this is very difficult due to linked deleterious teosinte traits.

Zea Perennis
''Zea perennis'', the perennial teosinte, is a true grass species in the genus '' Zea'' and a teosinte. Taxonomy It is one of the two perennial species in the genus ''Zea''. The other perennial, '' Z. diploperennis,'' is the sister taxon of ''Z. perennis''. Those two species also form a clade with '' Z. luxurians''. Together, the three species make up the ''Luxuriantes'' section in the genus ''Zea''. ''Z. perennis'' is the sole tetraploid in the genus and fertile hybrids with diploid ''Zea'' species are rare. Ribosomal ITS evidence suggested introgression between ''Z. perennis'' and '' Z. mays'' that must have come from either crossing the ploidy barrier or been from the diploid ancestral pool. ''Z. perennis'' is generally considered to be an autotetraploid from some ancestral population of ''Z. diploperennis''. Agriculture Due to the economic importance of maize, significant scientific interest exists in using the genes of the other ''Zea'' species for crop improvement. ''Z. pe ...

Paul Christoph Mangelsdorf
Paul Christoph Mangelsdorf (born in Atchison, Kansas on July 20, 1899; died July 22, 1989) was an American botanist and agronomist, known for his work on the origins of maize. Early life and education His father was a Prussian immigrant and his mother was also German. He studied at Kansas State University when it was still the "Kansas State Agricultural College" and received his bachelor's degree there in 1921. In 1921 he became Donald F. Jones's assistant in Connecticut and simultaneously furthered his studies at Harvard University, attaining his doctorate in 1925 under the direction of Edward Murray East, E. M. East. In 1927 Mangelsdorf became a researcher at the Texas AgriLife Research#History, Texas Agricultural Experiment Station, where he became interested in the genetic origins of maize. In 1940 he became a professor of economic botany at Harvard and continued his research there until his retirement in 1968. After his retirement, he continued his research at the University of ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (botany)
In botany, a section ( la, sectio) is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making new combinations, i.e. many new binomial names for the species involved. Examples: * ''Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * ''Plagiochila aerea'' Taylor is the type species of ''Plagiochila'' sect. ''Bursatae'' See also * Section (biology) References Section Section, Sectioning or Sectioned may refer to: Arts, entertainment and media * Section (music), a complete, but not independent, musical idea * Section (typography), a subdivision, especially ...
