• Information
  • Symbol: OsPDK1
  • MSU: LOC_Os07g44330
  • RAPdb: Os07g0637300
• Publication
  • Gibberellin regulates mitochondrial pyruvate dehydrogenase activity in rice, 2006, Plant Cell Physiol.
• Genbank accession number
  • AY026039
• Key message
  • OsPDK1 was expressed in leaf blade and leaf sheath but not in callus and root, while OsPDK2 was expressed constitutively in all tissues examined
  • These results suggest that gibberellin modulates the activity of mtPDC by regulating OsPDK1 expression and subsequently controlling plant growth and development
  • Maximum expression of OsPDK1 in leaf sheath was detected by Northern blot analysis when seedlings were treated with 5 microM GA3 for 24 h
  • The beta-glucuronidase (GUS) reporter gene, driven by a 2,067 bp OsPDK1 promoter region fragment, was mainly expressed in the aleurone layer of germinating seed and leaf sheath
  • OsPDK1 was identified as a gibberellin-up-regulated gene using a cDNA microarray
