• Information
  • Symbol: OsCOM1
  • MSU: LOC_Os06g41050
  • RAPdb: Os06g0613400
• Publication
  • The role of OsCOM1 in homologous chromosome synapsis and recombination in rice meiosis, 2012, Plant J.
  • COM1, a Factor of Alternative Non-homologous End Joining NHEJ, Lagging Behind the Classic NHEJ Pathway in Rice Somatic Cells., 2020, Plant J.
• Genbank accession number
  • AK119314
• Key message
  • Several key meiotic proteins, including ZEP1 and OsMER3, were not loaded normally onto chromosomes in Oscom1 mutants, whereas the localization of OsREC8, PAIR2 and PAIR3 seemed to be normal
  • Moreover, OsCOM1 was loaded normally onto meiotic chromosomes in Osrec8, zep1 and Osmer3 mutants, but could not be properly loaded in Osam1, pair2 and OsSPO11-1(RNAi) plants
  • These results provide direct evidence for the functions of OsCOM1 in promoting homologous synapsis and recombination in rice meiosis

  • OsCOM1, OsDMC1~DMC1B~OsDMC1B, OsDMC1 is not required for homologous pairing in rice meiosis., In the absence of OsDMC1, early recombination events probably occur normally, leading to normal localization of γH2AX, PAIR3, OsMRE11, OsCOM1 and OsRAD51C
  • OsCOM1, OsDMC1~DMC1B~OsDMC1B, OsDMC1 is not required for homologous pairing in rice meiosis., Moreover, OsDMC1 was not detected in pairing-defective mutants, such as pair2, pair3, Oscom1 and Osrad51c, while it was loaded onto meiotic chromosomes in zep1, Osmer3, Oszip4 and Oshei10
  • OsCOM1, ZYGO1, The F-box protein ZYGO1 mediates bouquet formation to promote homologous pairing, synapsis, and recombination in rice meiosis., The suppressed telomere clustering in homologous pairing aberration in rice meiosis 1 (pair1) zygo1 and rice completion of meiotic recombination (Oscom1) zygo1 double mutants, together with the altered localization of OsSAD1 (a SUN protein associated with the nuclear envelope) in zygo1 showed that ZYGO1 has a significant function in bouquet formation
