Effect of Temperature on Polyamine Oxidase Genes in Skeletonema dohrnii [PDF]

open access: yesInt J Mol Sci
In our experiments, we investigated the effect of temperature on diatom polyamine metabolism using Skeletonema dohrnii as an experimental algal species. We set three different temperature conditions for incubation and selected Skeletonema dohrnii in the ...

Defining novel plant polyamine oxidase subfamilies through molecular modeling and sequence analysis [PDF]

open access: yesBMC Evolutionary Biology, 2019
Background The polyamine oxidases (PAOs) catabolize the oxidative deamination of the polyamines (PAs) spermine (Spm) and spermidine (Spd). Most of the phylogenetic studies performed to analyze the plant PAO family took into account only a limited number ...

Polyamine metabolism as a regulator of cellular and organismal aging [PDF]

open access: yesAmino Acids
Polyamines - putrescine, spermidine, and spermine - are ubiquitous cationic molecules that are essential for cellular proliferation and homeostasis.

Evolution and Expression Analysis of PAO Gene Family in Cotton: Focusing on Fiber Development and Stress Response [PDF]

open access: yesPlants
Polyamines, a class of low-molecular-weight nitrogen-containing bases with high biological activity, are ubiquitous in organisms and play protective roles in plants under stress.

Responses of Polyamine-Metabolic Genes to Polyamines and Plant Stress Hormones in Arabidopsis Seedlings

open access: yesCells, 2021
In plants, many of the enzymes in polyamine metabolism are encoded by multiple genes, whose expressions are differentially regulated under different physiological conditions.

Inhibiting Copper Amine Oxidase Using L-Aminoguanidine Induces Cultivar and Age-Dependent Alterations of Polyamine Catabolism in Tomato Seedlings

open access: yesAgriculture, 2022
Many effects of polyamines (PAs) are well known in plant developmental processes; however, the significance of their catabolism is not well understood. Copper amine oxidase (CuAO) is involved in the degradation of diamine putrescine (Put).

The immunological effects of the polyamine oxidase enzyme partially cleared from the cerebrospinal fluid against secondary secondary cystitis in white mice. Coagulation factor and delayed hypersensitivity [PDF]

open access: yesمجلة التربية والعلم, 2007
The study included immune response to infection with secondary hydatid disease in BALB/c mice activated by partially purified cerebrospinal fluid-polyamine oxidase (CSF-PAO) with spermine and infected with protoscoleces of Echinococcus granulosus.

Potential role of NADPH-oxidase in early steps of lead-induced oxidative burst in Vicia faba roots [PDF]

open access: yes, 2008
The mechanism of oxidative burst induced by lead in Vicia faba excised roots was investigated by luminol-dependent chemiluminescence. Results showed that lead triggered a rapid and dose-dependent increase in chemiluminescence production.

Involvement of Polyamine Oxidase in Wound Healing [PDF]

open access: yesPlant Physiology, 2007
AbstractHydrogen peroxide (H2O2) is involved in plant defense responses that follow mechanical damage, such as those that occur during herbivore or insect attacks, as well as pathogen attack. H2O2 accumulation is induced during wound healing processes as well as by treatment with the wound signal jasmonic acid.
