Getting to the Root of Corn Domestication; Knowledge May Help Plant Breeders
Published:25 Apr.2022 Source:Penn State
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 teosinte, a perennial grass native to Mexico and Central America, more than 5,000 years ago.
There is much interest in how ancient agriculturists transformed the wild grass teosinte into modern corn, one of the most important and successful crops on earth, according to team leader Jonathan Lynch, distinguished professor of plant nutrition. 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.
