Effectiveness of phenoxyl radicals generated by peroxidase/H2O2-catalyzed oxidation of caffeate, ferulate, and p-coumarate in cooxidation of ascorbate and NADH
(Springer Japan Kk, Tokyo, 2008)
The rate of ascorbate and nicotinamide adenine dinucleotide plus hydrogen (NADH) cooxidation (i.e., their nonenzymic oxidation by peroxidase/H2O2-generated phenoxyl radicals of three hydroxycinnamates: caffeate, ferulate ...
Are leaf hydrogen peroxide concentrations commonly overestimated? The potential influence of artefactual interference by tissue phenolics and ascorbate
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2002)
We have examined the authenticity of two methods for determination of H2O2 in leaf tissue. We show that the high concentrations of ascorbic acid present in leaf extracts interfere with both techniques. In the chromogenic ...
Variability of antioxidant enzyme activity and isoenzyme profile in needles of Serbian spruce (Picea omorika (Panc.) Purkinye)
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Variations were studied of the activity and isoenzyme patterns of soluble peroxidase, catalase, catechol oxidase and superoxide dismutase, in needles of the Balkan endemic conifer Serbian spruce, Picea omorika (Panc.) ...
Characterisation of phenol oxidase and peroxidase from maize silk
(Wiley-Blackwell, Hoboken, 2010)
Silk of some maize genotypes contains a high level of phenolics that undergo enzymatic oxidation to form quinones, which condense among themselves or with proteins to form brown pigments. Two phenolic oxidizing enzymes, ...
Spatial distribution of apoplastic antioxidative constituents in maize root
(Wiley, Hoboken, 2021)
Apoplastic antioxidative constituents (enzymes, primary and secondary metabolites, ROS) from different root zones of hydroponically grown maize (Zea mays L.) were investigated using a noninvasive isolation procedure: filter ...
Silicon modulates the metabolism and utilization of phenolic compounds in cucumber (Cucumis sativus L.) grown at excess manganese
(Wiley-V C H Verlag Gmbh, Weinheim, 2007)
Cucumber plants (Cucumis sativus L. cv. Chinese long) were grown in nutrient solution with increasing manganese (Mn) concentrations (0.5, 50, and 100 mu M) with (+Si) or without silicon (-Si) supplied as silicic acid at ...
Antioxidative status and acclimatization capacity of bamboo - potential use for air quality improvement in urban areas
(Fresenius Environmental Bulletin, 2013)
Phyllostachis bissetti was introduced to urban areas in Belgrade with the aim to improve the quality of air polluted by heavy traffic. Dust released from fuel combustion adsorbed on the leaves reaching up to 10% of leaf ...
Differential response of antioxidative systems of maize (Zea mays L.) roots cell walls to osmotic and heavy metal stress
(Wiley, Hoboken, 2014)
An analysis of peroxidase and ascorbate oxidase activity, phenolic content and antioxidant capacity of isolated maize root cell walls was performed in controls and plants stressed with polyethylene glycol (PEG) or heavy ...
Changes in the antioxidative metabolism induced by drought and cd excess in the leaves of houseleek (sempervivum tectorum l.)
(Fresenius Environmental Bulletin, 2013)
House leek (Sempervivum tectorum L.), as a succulent CAM plant, withstands great water stress due to a CO2-concentrating mechanism. It is traditionally used as a medical plant, partly due to high foliar concentrations of ...
Silicon ameliorates manganese toxicity in cucumber by decreasing hydroxyl radical accumulation in the leaf apoplast
(Oxford Univ Press, Oxford, 2012)
This work was focused on the role of silicon (Si) in amelioration of manganese (Mn) toxicity caused by elevated production of hydroxyl radicals (center dot OH) in the leaf apoplast of cucumber (Cucumis sativus L.). The ...
