• Information
  • Symbol: DSM3,OsITPK2
  • MSU: LOC_Os03g12840
  • RAPdb: Os03g0230500
• Publication
  • Characterization of an inositol 1,3,4-trisphosphate 5/6-kinase gene that is essential for drought and salt stress responses in rice, 2011, Plant Mol Biol.
• Genbank accession number
  • AK100971
• Key message
  • ), we screened T-DNA mutants and identified a drought- and salt-hypersensitive mutant dsm3
  • Interestingly, overexpression of DSM3 (OsITPK2) in rice resulted in drought- and salt-hypersensitive phenotypes and physiological changes similar to those in the mutant
  • The expression level of DSM3 promoter-driven beta-glucuronidase (GUS) reporter gene in rice was induced by drought, salt and abscisic acid
  • These results together suggest that DSM3/OsITPK2 is an important member of the OsITPK family for stress responses, and an optimal expression level is essential for drought and salt tolerance in rice
  • Transcript level analysis of OsITPK genes revealed that they had different tempo-spatial expression patterns, and the responses of DSM3 to abiotic stresses, including drought, salinity, cold, and high temperature, were distinct from the other five members in rice
