What is teosinte?
Teosinte is a plant that grows in Mexico and Central America that looks like corn but they don't eat it. All species of teosinte are threatened or endangered ef extinction.
What is the name of an American grass used as forage spelled teo--- something?
Teosinte
Why doesn't corn on the cob follow the Fibonacci sequence?
...because it was domesticated from a plant called teosinte...
Where did people think popcorn came from?
Humans grow it all over the world today, but it all started in Mexico nearly 9,000 years ago. Long before maize, there was a plant called teosinte. If you saw teosinte in person, you probably wouldn't guess it's the grandparent of your popcorn.
What is corn mold?
Corn smut is a plant disease caused by the pathogenic fungus Ustilago maydis that causes smut on maize and teosinte
What is a plant that is corn's closest relative in the wild?
The plant that is corn's closest relative in the wild is teosinte. This is a wild plant that grows in Mexico.
What state did corn first come from?
It didn't really come from a state as much as it did from a country. It originally comes from a wild grass in Mexico called teosinte and was cultivated and bred into what it is today.
What is teosinte and where is it found?
Teosintes are a group of large grasses of the genus Zea found in Mexico, Guatemala, and Nicaragua. There are five recognized species of teosintes: Zea diploperennis, Zea perennis, Zea luxurians, Zea nicaraguensis and Zea mays. The last species, Zea mays, is divided into four further subspecies: ssp. huehuetenangensis, ssp. mays, ssp. mexicana, and ssp. parviglumis. Zea mays ssp. mays, also commonly known as maize or corn, is the only domesticated taxon in the genus Zea. The genus Zea includes both annual and perennial species. Zea diploperennis and Zea perennis are perennial, while all other taxa are annual, meaning they live for one to two years. Teosinte strongly resembles maize in many ways. Some populations of Zea mays ssp. mexicana have been observed having adapted to a maize-like form within cultivated maize fields. In some areas of Mexico, teosinte is regarded by maize farmers as a weed, while in other areas the farmers regard it as a beneficial companion plant, and encourage introgression. The the most significant way in which teosinte differs from maize is in its distinctively small female inflorescence, in the fact that they mature to form a two-ranked 'ear' of between five and ten hard, triangular or trapezoidal black seeds, quite unlike the characteristics of those of a maize. Not only that, but members of Zea exhibit no seed dormancy behavior - rather, they will germinate almost immediately in favorable conditions. The Mexican government has taken action in recent years to protect wild teosinte populations. The reason for this is based on the fact that virtually, all populations of teosinte are either threatened or endangered by the weeding that takes place in trying to get rid of them as a weed. For example, the species, Zea diploperennis, only exists in a very small population in a area of only a few square miles. Due to this action by the Mexican government in trying to protect the wild species of teosinte populations, scientific interests have been peaked, concerning the value and significance in the teosinte characteristics and traits, such as insect resistance and perennialism.
Who first grew corn?
Early mesoamericans living in the northern parts of what is now Mexico as long as 12,000 years ago bred, cross-bred and selected various grasses, one of which was probably teosinte, into what we now know as corn.
What is corn's original plant called?
Corn's origin may have been teosinte.From Wikipedia, page = "Maize":There are several theories about the specific origin of maize in Mesoamerica:It may be a direct domestication of a Mexican annual teosinte, Zea mays ssp. parviglumis, native to the Balsas River valley in south-eastern Mexico, with up to 12% of its genetic material obtained from Zea mays ssp. mexicana through introgression.It may have been derived from hybridization between a small domesticated maize (a slightly changed form of a wild maize) and a teosinte of section Luxuriantes, either Z. luxuriansor Z. diploperennis.It may have undergone two or more domestications either of a wild maize or of a teosinte.It may have evolved from a hybridization of Z. diploperennis by Tripsacum dactyloides. (The term "teosinte" describes all species and subspecies in the genus Zea, excluding Zea mays ssp. mays.) In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum, a related genus. However, the proposed role of tripsacum (gama grass) in the origins of maize has been refuted by modern genetic testing, refuting Mangelsdorf's model and the fourth listed above.The first model was proposed by Nobel Prize winner George Beadle in 1939. Though it has experimental support, it has not explained a number of problems, among them:how the immense diversity of the species of sect. Zeaoriginated,how the tiny archaeological specimens of 3500-2700 BC could have been selected from a teosinte, andhow domestication could have proceeded without leaving remains of teosinte or maize with teosintoid traits until ca. 1100 BC.
What was the original name for corn?
[1] The word corn came from the Old English corn, which came from the Germanic kurmo and then kornu, which came from the Indo-European gmom. The word refers to the main type of grain that's grown in an area. So corn means barley in North Africa, barley or wheat in England and Wales, and oats in Ireland and Scotland. [2] The plant corn is thought to have originated in Central America or Mexico. There are some, however, who think that the plant may have originated in the highlands of Peru. It's thought to be some 7,000-9,000 years old. It's in the grass family. And it's thought to have an unknown common ancestor with teosinte grass of Mexico. Some think that corn developed from teosinte. Some think that it developed from a relative of teosinte. And some think that it develoed from an interaction between teosinte and one of its relatives.
Where did corn first come from?
Corn was founded in Mesoamerica, modern day Mexico, with its ancestor being teosinte. The plant had great genetic motifications from its natural ancestor.
