Ancient Seeds in Mexico Help Fight Warming Effects. By Mica Rosenberg, Reuters, September 17, 2010. "More than 500 years after Spanish priests brought wheat seeds to Mexico to make wafers for the Catholic Mass, those seeds may bring a new kind of salvation to farmers hit by global warming. Scientists working in the farming hills outside Mexico City found the ancient wheat varieties have particular drought- and heat-resistant traits, like longer roots that suck up water and a capacity to store more nutrients in their stalks. They are crossing the plants with other strains developed at the International Maize and Wheat Improvement Center in El Batan to grow types of wheat that can fight off the ill effects of rising temperatures around the world."
