Expression

EC Number Organism Comment Expression
1.4.3.21 Arabidopsis thaliana at 24 h, the transcript levels of the gene of isoform CuAO3 decrease in plants exposed to abscisic acid or salicylic acid down
1.4.3.21 Arabidopsis thaliana isoform CuAO1 expression is not significantly affected by wounding and 1-aminocyclopropane-1-carboxylic acid treatment additional information
1.4.3.21 Arabidopsis thaliana isoform CuAO2 transcript levels, which are abundant in stems but low in other organs, are not observed to increase during the developmental stages and is not affected by treatments with abscisic acid, salicylic acid, and flagellin additional information
1.4.3.21 Arabidopsis thaliana isoform CuAO3 expression is not significantly affected by wounding and 1-aminocyclopropane-1-carboxylic acid treatment additional information
1.4.3.21 Arabidopsis thaliana isoform CuAO2 expression is clearly induced (about 12fold) in wounded and methyl jasmonate-treated plants at 8 h up
1.4.3.21 Arabidopsis thaliana isoform CuAO3 transcript levels increase during plant development, reaching a peak in flowers of adult plants, followed by leaves and stems. Isoform CuAO3 transcript accumulation is induced by abscisic acid, salicylic acid, flagellin and methyl jasmonate, at 8 h post-treatment. At 24 h the transcript levels of this gene increases in methyl jasmonate-treated plants up
1.4.3.21 Arabidopsis thaliana the expression of isoform CuAO1 increases about 3fold in 28-day-old seedlings when compared with 4-day-old. The highest expression of isoform CuAO1 is observed after 24 h in salicylic acid-treated plants (about 7.5-fold higher than basal level). The isoform expression is also up-regulated in response to methyl jasmonate, flagellin and abcisic acid, although at lower degree (about 3.5fold) up

General Information

EC Number General Information Comment Organism
1.4.3.21 physiological function polyamine catabolism in the Arabidopsis apoplast is mediated predominantly by copper-containing amine oxidases, while in peroxisomes the co-localization of copper-containing amine oxidase-dependent terminal catabolism with FAD-dependent amine oxidases-back-conversion machineries contributes to modulating putrescine-mediated inhibition of the back-conversion Arabidopsis thaliana
