AtPAO2 uORF has a regulatory role in regulating AtPAO2 expression. The fact that uORFs are commonly found in plant polyamine oxidase genes is relevant, implying that regulatory elements in the 5'-UTR of polyamine biosynthetic and catabolic genes might finely control the intracellular concentration of polyamines in plant development and stress responses |

cellular iron levels robustly regulate 13 polyamine pathway proteins. Four proteins are down-regulated (i.e., acireductone dioxygenase 1, methionine adenosyltransferase 2alpha, antizyme and polyamine oxidase) and three proteins are up-regulated (i.e., S-adenosyl methionine decarboxylase, antizyme inhibitor 1 and spermidine/spermine-N1-acetyltransferase 1). Depletion of iron also markedly decreases polyamine pools, (i.e., spermidine and/or spermine, but not putrescine) |

AtPAO3 mRNA rapidly accumulats in wounded plants 1 h after wounding and returns to almost basal levels 6 h thereafter. Seedlings treated with flagellin 22, a pathogen elicitor that activates the plant basal defense, exhibits AtPAO3 induction after the 6-h time point, with constant increase up to 24 h |

expression is up-regulated by thermospermine treatment |

expression of the enzyme OsPAO1 appears to be quite low under physiological conditions, but is markedly induced in rice roots by spermine or thermospermine treatment |

| 1.5.3.17 | up |
isoforms PAO1 and PAO2 genes are transcriptionally up-regulated in plants infected by Pseudomonas syringae |

NO3- induced AtPAO2::GUS expression is quenched by the presence of NH4+ in the growth medium and abscisic acid-induced AtPAO2::GUS expression is more prominent when the plants are grown on NO3- as the only N source. PAO2OX (an AtPAO2 over-expressing transgenic line) is partially unresponsive to abscisic acid in some growth conditions depending on N-source, pao2 mutants being often more sensitive to abscisic acid than the similarly grown WT |
