Review: New routes for plant iron mining
Iron (Fe) is a frequently limiting nutrient for plant growth. Iron uptake requires that plants manipulate the extracellular environment through secretion of protons, chelators and other molecules. Curie and Mari review new studies on the importance of coumarin (phenolic compound) secretion in iron uptake, the role of the endodermis, and the role of cell walls and other apoplastic spaces as reservoirs of iron, as well as how the hormones ethylene and ABA contribute to iron homeostasis. New insights into how the developing embryo secures iron from maternal tissues are also described. New Phytol. 10.1111/nph.14364
