However, a researcher at the University of Missouri-Columbia is taking steps to help change those statistics for the betterment of society.

Elizabeth Rogers, Assistant Professor of Nutritional Sciences, is trying to understand how plants acquire iron from the soil and how to identify and characterize the genes involved in iron sensing, regulation, and transport in plants. Understanding iron uptake in plants is extremely important because one-third of the world's soils are deficient in iron.

"For most people, plant material is the major source of iron, so assisting plants to have higher stores of bioavailable iron will help both plant productivity and human nutrition," she said.

Dr. Rogers is using the modefplant Arabidopsis thalilana to examine how plants obtain iron from soil. First, the plant determines whether it has enough iron for growth or whether it needs to obtain more from soil. …
