    • In vegetative organs, OsYSL18 was specifically expressed in lamina joints, the inner cortex of crown roots, and phloem parenchyma and companion cells at the basal part of every leaf sheath
    • OsYSL18 is a rice iron(III)-deoxymugineic acid transporter specifically expressed in reproductive organs and phloem of lamina joints
    • Electrophysiological measurements using Xenopus laevis oocytes showed that OsYSL18 transports iron(III)-deoxymugineic acid, but not iron(II)-nicotianamine, zinc(II)-deoxymugineic acid, or zinc(II)-nicotianamine
    • OsYSL18 promoter-beta-glucuronidase (GUS) analysis revealed that OsYSL18 was expressed in reproductive organs including the pollen tube
    • Reverse transcriptase PCR analysis revealed more OsYSL18 transcripts in flowers than in shoots or roots
    • These results suggest that OsYSL18 is an iron-phytosiderophore transporter involved in the translocation of iron in reproductive organs and phloem in joints
