What's a GeneRIF?
  1. Underexpression of Zea mays polyamine oxidase (ZmPAO) correlates with increased thermotolerance of the photosynthetic machinery and improved biomass accumulation, accompanied by enhanced levels of the enzymatic and non-enzymatic antioxidants, whereas ZmPAO overexpressors exhibit significant impairment of thermotolerance.
    Title: Underexpression of apoplastic polyamine oxidase improves thermotolerance in Nicotiana tabacum.
  2. deregulation of the apoplastic PAO can be further examined as a potential approach to breed plants with enhanced/reduced tolerance to abiotic stress with minimal associated trade-offs.
    Title: Deregulation of apoplastic polyamine oxidase affects development and salt response of tobacco plants.
  3. data suggest that H2O2 produced through PA catabolism by ZmPAO1 plays an important role in tumor development during the maize-U. maydis interaction.
    Title: Inhibition of polyamine oxidase activity affects tumor development during the maize-Ustilago maydis interaction.
  4. Rsults indicate that the HOH309-K300 couple plays a major role in multiple steps of ZmPAO catalytic mechanism, such as correct substrate binding geometry as well as FAD reduction and reoxidation kinetics.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
