• Information
  • Symbol: OsATX
  • MSU: LOC_Os01g61070
  • RAPdb: Os01g0826000
• Publication
  • Characterization of a novel rice gene OsATX and modulation of its expression by components of the stress signalling pathways, 2002, Physiol Plant.
• Genbank accession number
  • AJ308374
• Key message
  • Nipponbare) gene, OsATX, a single copy gene, from the JA treated rice seedling leaves cDNA library
  • Additionally, co-application of either JA or ABA with SA drastically suppressed the induced OsATX mRNA level
  • OsATX was responsive to cutting (wounding by cutting the excised leaf), over its weak constitutive expression in the healthy leaves
  • The critical signalling molecules, jasmonic acid (JA), salicylic acid (SA), abscisic acid (ABA), and hydrogen peroxide, together with protein phosphatase inhibitors, effectively up-regulated the OsATX expression with time, over the excised leaf cut control, whereas ethylene had no affect
  • Finally, the blast pathogen, Magnaporthe grisea, triggered OsATX mRNA accumulation
  • These results strongly suggest a function/role(s) for OsATX in defense/stress responses in rice
