Abstract excerpt

Iron (Fe) is a transition metal necessary for achieving essential physiological processes throughout the plant lifecycle. In Arabidopsis thaliana, secreting Fe-mobilizing coumarins (FMC) is a key mechanism enabling roots to acquire nonbioavailable Fe present in soils. Here, we unveil the pivotal role played by NRT1/PTR FAMILY 7.2 (NPF7.2) in coumarin secretion by conducting phenotypic analyses of NPF7.2...
