Teosinte - Native-Seeds-Search
Teosinte is an extremely important crop, as it believed that the subspecies parviglumis is the wild progenitor of corn. About 9,000 years ago, teosinte grew wild, as a grass-like plant, with a grain in a tough shell that was dispersed only when ripe.
Scientists take major step in understanding domestication of corn ...
2022年2月2日 · Iowa State University scientists are learning how to peer back through millennia of domestication to learn how a wild grassy plant known as teosinte developed into corn, the modern cash crop grown across the globe.
Evolution of Corn - University of Utah
Through the study of genetics, we know today that corn's wild ancestor is a grass called teosinte. Teosinte doesn't look much like maize, especially when you compare its kernals to those of corn. But at the DNA level, the two are surprisingly alike.
To Decode the Mystery of Corn, Smithsonian Scientists Recreate Earth as ...
2014年2月11日 · Corn, a crop that is farmed on every continent except for Antarctica, looks very little like its ancestor, a wild grass with hard kernels that grows today in southwestern Mexico and is called...

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.
Ancient DNA Reveals The Surprisingly Complex Origin Story of Corn
2018年12月13日 · In Mexico, corn tortillas rule the kitchen. After all, maize began evolving there from a grass called teosinte some 9,000 years ago, eventually becoming a staple consumed around the world. But that spread presents a puzzle.
Teosinte | Mexican, Wild Grains, Maize | Britannica
Domesticated corn, or maize (Zea mays mays), was derived from the Balsas teosinte (Z. mays parviglumis) of southern Mexico in pre-Columbian times more than 6,000 years ago. Teosintes are solitary (single-stalked) annuals or spreading perennials.

Popped Secret: The Mysterious Origin of Corn - BioInteractive
2015年3月2日 · This film explores the genetic and archaeological evidence that suggest that corn is the result of the domestication of a wild Mexican grass called teosinte. Ten thousand years ago, corn didn’t exist anywhere in the world, and until recently scientists argued …
Corn and its untamed cousins: wild genes in domestic crops
Scientists have discovered that domestic corn and wild teosinte are evolutionary cousins — research suggests that native Americans domesticated maize from wild teosinte stocks using artificial selection — and so genes found in teosinte may also be useful in corn.
