Maize Strength


Maize is known in many English-speaking countries as corn but is technically a grain domesticated by indigenous peoples in Mesoamerica in prehistoric times. The leafy stalk produces ears which contain seeds called kernels. Though technically a grain, maize kernels are used in cooking as a vegetable or starch. The Olmec and Mayans cultivated it in numerous varieties throughout central and southern Mexico. Between 1700 and 1250 BC, the crop spread through much of the Americas. The region developed a trade network based on surplus and varieties of maize crops. After European contact with the Americas in the late 15th and early 16th centuries, explorers and traders carried maize back to Europe and introduced it to other countries. Now the discovery of a new provisioning gene in maize plants that regulates the transfer of nutrients from the plant to the seed could lead to increased crop yields and improve food security. Scientists from Oxford University and the University of Warwick, in collaboration with agricultural biotech research company Biogemma-Limagrain, have identified the gene, called Meg 1.
