• Publication
  • Comprehensive analysis of rice DREB2-type genes that encode transcription factors involved in the expression of abiotic stress-responsive genes, 2010, Mol Genet Genomics.
• Genbank accession number
  • AK099221
• Key message
  • Transgenic Arabidopsis plants overexpressing OsDREB2B showed enhanced expression of DREB2A target genes and improved drought and heat-shock stress tolerance
  • These results suggest that OsDREB2B is a key gene that encodes a stress-inducible DREB2-type transcription factor that functions in stress-responsive gene expression in rice
  • Only OsDREB2A and OsDREB2B showed abiotic stress-inducible gene expression
• Connection
  • OsDREB2B, OsMKK1, The mitogen-activated protein kinase cascade MKK1-MPK4 mediates salt signaling in rice., By comparing the transcription factors levels between WT and osmkk1 mutant, OsMKK1 was necessary for salt-induced increase in OsDREB2B and OsMYBS3
  • OsDREB2B, OsJRL, OsJRL, a rice jacalin-related mannose-binding lectin gene, enhances Escherichia coli viability under high-salinity stress and improves salinity tolerance of rice., Overexpression of OsJRL in rice also enhanced salinity tolerance and increased the expression levels of a number of stress-related genes, including three LEA (late embryogenesis abundant proteins) genes (OsLEA19a, OsLEA23 and OsLEA24), three Na(+) transporter genes (OsHKT1;3, OsHKT1;4 and OsHKT1;5) and two DREB genes (OsDREB1A and OsDREB2B)
