• Information
  • Symbol: OsNek3
  • MSU: LOC_Os07g08000
  • RAPdb: Os07g0176600
• Publication
  • Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11, 2009, Plant Cell Physiol.
• Genbank accession number
  • AK067073
• Key message
  • On the other hand, plants overexpressing OsNek3 occasionally produced a peculiar pollen structure in which the outer cell wall of four pollen grains fused together even at the mature pollen stages, which resembled that of quartet mutants in Arabidopsis
  • OsNek3 was preferentially expressed in mature pollen
  • A knockout mutant with Tos17 inserted into OsNek3 did not show any pollen-defective phenotype
  • OsNek3 was shown to interact with a LIM domain-containing protein, OsPLIM2b, whose expression was strongly specific in mature pollen, suggesting that OsNek3 might play a role in pollen germination
  • Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11
  • These results suggest that OsNek3 is downstream of DCW11 in retrograde signaling from the mitochondria to the nucleus and is involved in CW-CMS
• Connection
  • DCW11, OsNek3, Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11, Here we show the relationship between OsNek3 and DCW11
  • DCW11, OsNek3, Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11, OsNek3 was shown to be down-regulated in DCW11-knockdown lines, whereas osnek3 mutation did not result in DCW11 down-regulation
  • DCW11, OsNek3, Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11, These results suggest that OsNek3 is downstream of DCW11 in retrograde signaling from the mitochondria to the nucleus and is involved in CW-CMS
  • DCW11, OsNek3, Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11, Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11
  • OsNek3, OsPLIM2b, Cytoplasmic male sterility-related protein kinase, OsNek3, is regulated downstream of mitochondrial protein phosphatase 2C, DCW11, OsNek3 was shown to interact with a LIM domain-containing protein, OsPLIM2b, whose expression was strongly specific in mature pollen, suggesting that OsNek3 might play a role in pollen germination
