Scientists Trace Corn Ancestry from Ancient Grass to Modern Crop

Researchers have identified corn genes that were preferentially selected by Native Americans during the course of the plant's domestication from its grassy relative, teosinte, (pronounced "tA-O-'sin-tE") to the single-stalked, large-eared plant we know today. The study revealed that of the 59,000 total genes in the corn genome, approximately 1,200 were preferentially targeted for selection during its domestication.
The study, by University of California, Irvine's Brandon Gaut and his colleagues, appears in the May 27 issue of the journal, Science.
