Permease for high affinity iron uptake (PubMed:17138696). Expression regulated by iron through the urbs1 transcription factor (PubMed:17138696). During pathogenic development, expression is confined to the phase of hyphal proliferation inside the plant (PubMed:17138696). Strongly reduces virulence (PubMed:17138696). Belongs to the oxidase-dependent Fe transporter (OFeT) (TC 9.A.10.1) family.
