Abstract

Fe deficiency commonly limits plant growth and crop yields. If the mechanisms of Fe uptake, distribution, and regulation were clearly understood, it might be feasible to engineer plants better able to grow in soils now considered marginal and to increase crop biomass in soils now in cultivation. Furthermore, plants that serve as better sources of this essential element would improve human nutrition because most people rely on plants as their dietary source of Fe. Here we review our current understanding of Fe homeostasis in plants, emphasizing the challenges of safely transporting and storing this essential redox-active metal.
