• Information
  • Symbol: ARAG1
  • MSU: LOC_Os02g43970
  • RAPdb: Os02g0657000
• Publication
  • ARAG1, an ABA-responsive DREB gene, plays a role in seed germination and drought tolerance of rice, 2010, Ann Bot.
• Genbank accession number
  • BAG98540
  • AK108830

  • AK108830
• Key message
  • ARAG1, an ABA-responsive DREB gene, plays a role in seed germination and drought tolerance of rice
  • KEY RESULTS: ARAG1 was expressed in inflorescences, roots, immature embryos and germinating seeds, but not in coleoptiles, leaves or mature embryos
  • ARAG1 knockdown line was hypersensitive to ABA application during seed germination and seedling growth
  • CONCLUSIONS: These results indicate that ARAG1 was involved in the ABA signalling and stress responsive pathways
  • Knockdown of ARAG1 weakened tolerance of the transgenic seedlings to drought stress, while over-expression of it increased the tolerance slightly
