AbstractThe long-distance transport of metal micronutrients (e.g., Fe) is crucial for plant growth and reproduction. The path of metals to its final destination (e.g., the chloroplast) involves transport across multiple membranes mediated by different transporter proteins, as well as metal complexation by different ligands (e.g., nicotianamine and citrate) in each compartment within the path. A complete picture of this complex process is still lacking for any metal, in part because data on metal and ligand concentrations in plant fluids are still scarce.
The aim of this work was to investigate the effects of Fe deficiency and Fe resupply on the concentrations of metals and ligands in xylem sap and in apoplastic fluids and intracellular extracts of leaves (old and young) and roots in tomato.
