• Information
  • Symbol: HAZ1,HOX1a
  • MSU: LOC_Os06g12400
  • RAPdb: Os06g0229300
• Publication
  • Radial axis differentiation in a globular embryo is marked by HAZ1, a PHD-finger homeobox gene of rice, 2004, Gene.
  • Rice homeobox transcription factor HOX1a positively regulates gibberellin responses by directly suppressing EL1, 2011, J Integr Plant Biol.
• Genbank accession number
  • AB081340
  • AK121314
  • AB081340
  • AK121314
• Key message
  • In addition, HOX1a suppresses the transcription of early flowering1 (EL1), a negative regulator of GA signaling, and further electrophoretic mobility shift assay and chromatin immunoprecipitation analysis revealed that HOX1a directly bound to the promoter region of EL1 to suppress its expression and stimulate GA signaling
  • We here show that overexpression of rice homeobox gene HOX1a resulted in enhanced gibberellin (GA) response, indicating a positive effect of HOX1a in GA signaling
  • Rice homeobox transcription factor HOX1a positively regulates gibberellin responses by directly suppressing EL1
  • HOX1a is induced by GA and encodes a homeobox transcription factor with transcription repression activity
  • These results demonstrate that HOX1a functions as a positive regulator of GA signaling by suppressing EL1, providing informative hints on the study of GA signaling
