Iron Uptake, Translocation, and Regulation in Higher Plants

WebIron (Fe) is one of the most important micronutrient elements in plants as it is involved in many cellular functions (e.g., photosynthesis and respiration). Any defect in Fe availability will impact plant growth and development as well as crop yield and plant product quality ( Briat et al., 2015 ). WebIron sensing in mammals and plants. In mammalian cells, Fe is sensed via IRP1 and IRP2, which bind to IREs to regulate the translation of genes involved in the uptake and storage of Fe.
