This figure from the paper shows the evolution of root types from teosinte to modern corn over the last 10 000 years, simulated using the modeling program OpenSimRoot, which was developed by ...

A unique confluence of archeology, molecular genetics and serendipity guided a collaboration of Mexican and Penn State researchers to a deeper understanding of how modern corn was domesticated from ...

You can’t construct a strong building on a weak foundation, and you can’t grow a great corn crop on a weak root system. From freezing temperatures to voracious underground pests and other threats, ...

A new discovery, reported in a global study that encompassed more than a decade of research, could lead to the breeding of corn crops that can withstand drought and low-nitrogen soil conditions and ...

Wondering what’s causing stunted growth and wilting in your corn field? First, examine the roots. You might find evidence of seed corn maggot or cutworm damage in the corn root system. But there are ...

Dr. Dan Quinn, Purdue Corn Agronomist, shared his experience with abnormal mesocotyl growth of corn seedlings in the most recent Pest & Crop Newsletter. As a young agronomist, one of the first things ...

Corn is a colossal grain in the global food and feed chain, with the U.S. producing roughly 30% of the world's supply, or nearly 278 million metric tons in the 2024–25 growing season alone. But its ...

Corn was domesticated from its ancestor teosinte in central Mexico beginning about 9,000 years ago by humans selectively breeding the wild plant, transforming its small, hard-shelled kernels into the ...

For decades, his research group in the College of Agricultural Sciences has been uncovering how roots play a critical role in plant development and survival. "Corn is no exception, and it turns out ...
