• Publication
  • OsYSL18 is a rice ironIII-deoxymugineic acid transporter specifically expressed in reproductive organs and phloem of lamina joints, 2009, Plant Mol Biol.
• Genbank accession number
  • AB190926
• Key message
  • 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
