New research reveals the earliest evidence for corn in the New World

Among the hundreds of plants that have been domesticated in the New World, none has received as much attention or been subject to as much debate as corn, or maize (Zea mays L.), arguably the most important crop of the Americas. Controversies have existed for years over what the wild ancestor of ma...

If corn is biofuels king, tropical maize may be emperor

When University of Illinois crop scientist Fred Below began growing tropical maize, the form of corn grown in the tropics, he was looking for novel genes for the utilization of nitrogen fertilizer and was hoping to discover information that could be useful to American corn producers. Now, howe...

Increase in ethanol production from corn could significantly impact
