Gene Details:

• MSU gene ID: LOC_Os12g36620
• RAPdb gene ID: Os12g0552300
• Gene Symbol: PPS1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
