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 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. 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. Researchers are studying ''Z. diploperennis'' as its genes provide resistance against ''Striga ''Striga'', commonly known as witchweed, is a genus of parasitic plants that occur naturally in parts of Africa, Asia, an ...

Zea Luxurians
''Zea luxurians'', also referred to by the common names Maíz de Monte, Florida teosinte and Guatemalan teosinte, is a species of flowering plant in the family Poaceae. It is a true grass and a teosinte. Distribution It is native to Guatemala, Honduras and Mexico, but it can also be found in areas where it has been introduced, including Brazil, Colombia, and French Guiana French Guiana ( or ; french: link=no, Guyane ; gcr, label=French Guianese Creole, Lagwiyann ) is an overseas departments and regions of France, overseas department/region and single territorial collectivity of France on the northern Atlantic ....Silva, NCdA., et al. 201Presence of ''Zea luxurians'' (Durieu and Ascherson) Bird in Southern Brazil: Implications for the Conservation of Wild Relatives of Maize.PLoS ONE 10(10): e0139034.

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 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 ...

Dioon
''Dioon'' is a genus of cycads in the family Zamiaceae. It is native to Mexico and Central America. Their habitats include tropical forests, pine-oak forest, and dry hillsides, canyons and coastal dunes. Description Dioons are dioecious, palmlike shrubs with cylindrical stems, usually with many leaves. The species in the genus Dioon are perennial, evergreen cycads with cylindrical stem axis is partially in the ground. The plant is thickened and made of soft wood, rarely having above ground branches. Leaf bases are persistent or shedding to leave smooth bark. The leaves are pinnate, spirally arranged, interspersed with cataphylls, with leaflets not articulated and lacking a midrib. The lower leaflets are often reduced to spines. The sporophylls are not in vertical rows in cones, and the megasporophyll apices are broadly flattened, upturned, and overlapping. Species in the genus Dioon have 2n = 18 chromosomes. The largest species is D. spinolosum, which are over 16 meters high an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
