What's a GeneRIF?

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.
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.
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.
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.
Title: The structure of maize polyamine oxidase K300M mutant in complex with the natural substrates provides a snapshot of the catalytic mechanism of polyamine oxidation.
PAO contributes to sustain maize leaf elongation under saline stress.
Title: Polyamine oxidase activity contributes to sustain maize leaf elongation under saline stress.
MPAO contributes to abscisic acid-induced cytosolic antioxidant defense through hydrogen peroxide, a Spermidine catabolic product.
Title: Involvement of polyamine oxidase in abscisic acid-induced cytosolic antioxidant defense in leaves of maize.
This study evaluated the effect of wounding on polyamine oxidase expression in the outer tissues of the maize mesocotyl and provide evidence that its activity, protein, and mRNA levels increased in response to wounding as well as jasmonic acid treatment.
Title: Involvement of polyamine oxidase in wound healing.
Data indicate the importance of lysine300 and probable importance of water309 to the mechanism of flavin reduction in maize polyamine oxidase.
Title: Lys300 plays a major role in the catalytic mechanism of maize polyamine oxidase.

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.
