• Key message
  • OsPK4 and OsPK7 proteins produced in Escherichia coli were able to phosphorylate themselves and myelin basic proteins, the reaction requiring magnesium and/or manganese ions
  • Diverse response of rice and maize genes encoding homologs of WPK4, an SNF1-related protein kinase from wheat, to light, nutrients, low temperature and cytokinins
  • The wheat gene WPK4 encodes a 56-kDa protein kinase that belongs to group 3 of the SNF1-related protein kinase family (SnRK3), and is up-regulated by light and cytokinins and down-regulated by sucrose
  • Transcripts of OsPK4 were detected in all tissues tested, and amounts were increased upon illumination, nutrient deprivation and treatment with cytokinins
  • Both OsPK1 and OsPK4 localized to the mitochondria and cytosol and were recruited to the mitochondria by OsPK3
• Connection
  • OsPK3, PK4~OsPK4~OsCIPK19, Mitochondria-associated pyruvate kinase complexes regulate grain filling in rice., Subcellular localization analysis of OsPK3 revealed its association with mitochondria, and OsPK3 physically interacted and formed heterodimers in vivo with two other PK isozymes, OsPK1 and OsPK4
  • OsPK3, PK4~OsPK4~OsCIPK19, Mitochondria-associated pyruvate kinase complexes regulate grain filling in rice., Both OsPK1 and OsPK4 localized to the mitochondria and cytosol and were recruited to the mitochondria by OsPK3
  • OsPK3, PK4~OsPK4~OsCIPK19, Mitochondria-associated pyruvate kinase complexes regulate grain filling in rice., As observed for ospk3, disruption of OsPK1 caused pleiotropic defects, while OsPK4 loss of function led to severely chalky grains without other obvious defects
  • OsPK1, PK4~OsPK4~OsCIPK19, Mitochondria-Associated Pyruvate Kinase Complexes Regulate Grain Filling in Rice , Subcellular localization analysis of OsPK3 revealed its association with mitochondria, and OsPK3 physically interacted and formed heterodimers in vivo with two other PK isozymes, OsPK1 and OsPK4
