• Information
  • Symbol: OsALS1
  • MSU: LOC_Os03g54790
  • RAPdb: Os03g0755100
• Publication
  • A tonoplast-localized half-size ABC transporter is required for internal detoxification of aluminum in rice, 2012, Plant J.
  • Base-Editing-Mediated Artificial Evolution of OsALS1 in planta to Develop Novel Herbicide-Tolerant Rice Germplasms., 2020, Mol Plant.
• Genbank accession number
  • AK066049
• Key message
  • OsALS1 encodes a half-size ABC transporter that is a member of the TAP (transporter associated with antigen processing) sub-group
  • Here we functionally characterized a rice gene, Os03g0755100 (OsALS1), that is regulated by ART1, a C2H2-type zinc finger transcription factor
  • Expression of OsALS1 was rapidly and specifically induced by Al in the roots, but not by other metals or low pH
  • OsALS1 was localized at all cells of the roots
  • Comparison of Al accumulation patterns between wild-type and osals1 mutants showed that there was no difference in Al levels in the cell sap of root tips between wild-type and the mutants, but the mutants accumulated more Al in the cytosol and nucleus than the wild-type
