• Information
  • Symbol: OsIBR5
  • MSU: LOC_Os06g20340
  • RAPdb: Os06g0308100
• Publication
  • Rice MAPK phosphatase IBR5 negatively regulates drought stress tolerance in transgenic Nicotiana tabacum, 2012, Plant Sci.
• Genbank accession number
  • AK071054
• Key message
  • These results indicated that OsIBR5 is a MKP which was induced by abiotic stresses and decreased tolerance to drought stress in transgenic tobacco plants
  • Drought and ABA-induced stomatal closure was significantly reduced in OsIBR5-overexpressing tobacco plants compared with controls
  • Overexpression of OsIBR5 in tobacco plants resulted in hypersensitivity to drought and H(2)O(2) treatments
  • Moreover, OsIBR5 was found to interact with tobacco MAPKs SIPK and WIPK, and drought-induced WIPK activity was impaired in OsIBR5-overexpressing tobacco plants
