Single gene controls key difference between maize and its wild ancestor

Madison, Wis. -- One of the greatest agricultural and evolutionary puzzles is the origin of maize -- and part of the answer may lie in a plot of corn on the western edge of Madison, where a hybrid crop gives new life to ancient genetic material.

While many biologists argue that teosinte, a wild Mexican grass, is the progenitor of maize, others believe that the differences between t......

However, the genetic changes that occurred during the domestication of corn have been a controversial issue in the field of evolutionary biology, Doebley says. "Some argue that evolution works like building up a sandstone cliff with lots of tiny grains deposited over a very long ti......

Doebley's team for the Nature paper included Huai Wang, a current postdoctoral student; Qiong Zhao, a current graduate student; Yves Vigouroux, a former postdoctoral student; Kirsten Bomblies and Lewis Lukens, former graduate students; Tina Nussbaum-Wagler, a research specialist; and Bailin Li and Mariana Faller, researchers at the DuPont corporation.
