• Information
  • Symbol: OsVIT1
  • MSU: LOC_Os04g38940
  • RAPdb: Os04g0463400
• Publication
  • Vacuolar membrane transporters OsVIT1 and OsVIT2 modulate iron translocation between flag leaves and seeds in rice, 2012, Plant J.
• Genbank accession number
  • AK059730
• Key message
  • Vacuolar membrane transporters OsVIT1 and OsVIT2 modulate iron translocation between flag leaves and seeds in rice
  • In rice, OsVIT1 and OsVIT2 are highly expressed in flag leaf blade and sheath, respectively, and in contrast to OsVIT1, OsVIT2 is highly responsive to Fe treatments
  • Interestingly, functional disruption of OsVIT1 and OsVIT2 leads to increased Fe/Zn accumulation in rice seeds and a corresponding decrease in the source organ flag leaves, indicating an enhanced Fe/Zn translocation between source and sink organs, which might represent a novel strategy to biofortify Fe/Zn in staple foods
• Connection
  • OsVIT1, OsVIT2, Vacuolar membrane transporters OsVIT1 and OsVIT2 modulate iron translocation between flag leaves and seeds in rice, In this study we report the isolation and functional characterization of two rice genes OsVIT1 and OsVIT2, orthologs of the Arabidopsis VIT1
  • OsVIT1, OsVIT2, Vacuolar membrane transporters OsVIT1 and OsVIT2 modulate iron translocation between flag leaves and seeds in rice, Transient expression of OsVIT1:EGFP and OsVIT2:EGFP protein fusions revealed that OsVIT1 and OsVIT2 are localized to the vacuolar membrane
  • OsVIT1, OsVIT2, Vacuolar membrane transporters OsVIT1 and OsVIT2 modulate iron translocation between flag leaves and seeds in rice, Ectopic expression of OsVIT1 and OsVIT2 partially rescued the Fe(2+) - and Zn(2+) -sensitive phenotypes in yeast mutant Deltaccc1 and Deltazrc1, and further increased vacuolar Fe(2+) , Zn(2+) and Mn(2+) accumulation
  • OsVIT1, OsVIT2, Vacuolar membrane transporters OsVIT1 and OsVIT2 modulate iron translocation between flag leaves and seeds in rice, These data together suggest that OsVIT1 and OsVIT2 function to transport Fe(2+) , Zn(2+) and Mn(2+) across the tonoplast into vacuoles in yeast
  • OsVIT1, OsVIT2, Vacuolar membrane transporters OsVIT1 and OsVIT2 modulate iron translocation between flag leaves and seeds in rice, In rice, OsVIT1 and OsVIT2 are highly expressed in flag leaf blade and sheath, respectively, and in contrast to OsVIT1, OsVIT2 is highly responsive to Fe treatments
