Iron deficiency responses. (Upper) The reduction strategy as typified by Arabidopsis is shown. An inducible ferric chelate reductase, FRO2, reduces Fe(III) chelates in the soil, releasing Fe2+ for transport across the plasma membrane by the Fe2+ transporter IRT1. Plasma membrane ATPase activity is also increased under iron deficiency, acidifying the rhizosphere and increasing Fe solubility. (Lower) The chelation strategy as typified by maize and rice is shown. Phytosiderophores (PS) are synthesized in the cytoplasm. PS are released into the soil, and Fe–PS complexes are subsequently transported across the membrane via the YS1 transporter. See Grotz and Guerinot (8) for a more detailed description of these responses.
