Dartmouth College scientists have discovered a gene in plants that’s controls how much iron the plant takes in from the soil. Mary Lou Guerinot, a professor of biological sciences at Dartmouth, was part of the team that discovered the gene. “What we’ve been studying is how plants take up iron from the soil with the goal of making food people eat more nutritious,” she said. The gene Guerinot and other researchers discovered, Upstream Regulator of I-R-T-1, also known as URI, controls when genes should be expressed in the root of the plant to begin iron uptake. Guerinot says crops like rice, wheat and cassava form the staple diets for half the world’s population. But those foods don’t have a lot of iron. About two billion people around the world...
