• Information
  • Symbol: PPS1
  • MSU: LOC_Os12g36620
  • RAPdb: Os12g0552300
• Publication
  • Rice PPS1 encodes a DYW motif-containing pentatricopeptide repeat protein required for five consecutive RNA-editing sites of nad3 in mitochondria., 2018, New Phytol.
  • Silencing of rice PPR gene PPS1 exhibited enhanced sensibility to abiotic stress and remarkable accumulation of ROS, 2021, J Plant Physiol.
• Genbank accession number
  • XP_015618345.1
• Key message
  • Both pps1 RNAi and heterozygous plants are characterized by delayed development and partial pollen sterility at vegetative stages and reproductive stage
  • In our recent study, we found that the knockout of rice PPS1 causes pleiotropic growth disorders, including growth retardation, dwarf and sterile pollen, and finally leads to impaired C-U RNA editing at five consecutive sites on the mitochondrial nad3
  • In this study, we further investigate the roles of PPS1 in abiotic stress tolerance, we confirmed that pss1-RNAi line exhibited enhanced sensitivity to salinity and ABA stress at vegetative stage, specifically
  • Silencing of rice PPR gene PPS1 exhibited enhanced sensibility to abiotic stress and remarkable accumulation of ROS
  • These results implied that PPS1 functioned on ROS signaling network to contribute for the flexibility to abiotic stresses
• Connection
  • NAD3, PPS1, Silencing of rice PPR gene PPS1 exhibited enhanced sensibility to abiotic stress and remarkable accumulation of ROS, In our recent study, we found that the knockout of rice PPS1 causes pleiotropic growth disorders, including growth retardation, dwarf and sterile pollen, and finally leads to impaired C-U RNA editing at five consecutive sites on the mitochondrial nad3
