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 ...
Enzymatic Profile of 'Willamette' Raspberry Leaf and Fruit Affected by Prohexadione-Ca and Young Canes Removal Treatments
(Amer Chemical Soc, Washington, 2017)
The influence of growth regulator prohexadione-Ca (ProCa) concurrently with young canes removal on the modification of photosynthetic pigments content and antioxidant enzymes (peroxidase, POD; catalase, CAT; polyphenol ...
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 ...
Characterization of enzymatically synthesized diferulate
(New York Acad Sciences, New York, 2005)
Horseradish peroxidase was used to synthesize diferulates by a procedure in which ethyl ferulate was used as substrate. Four different forms were obtained, of which two dominant were the 5-5' and 8-5' diferulate. Fluorescence ...
Induction of peroxidases and superoxide dismutases in transformed embryogenic calli of alfalfa (Medicago sativa L.)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
Peroxidase (POD) and superoxide dismutase (SOD) enzyme activities were analyzed in non-regenerative transformed embryogenic lines of alfalfa (Medicago sativa L.) carrying wound-inducible oryzacystatin I (OC-I), wound-inducible ...
Changes in Chenopodium rubrum seeds with aging
(New York Acad Sciences, New York, 2005)
We studied antioxidative system, germination, growth, and flowering in vitro in Chenopodium rubrum seeds of different ages. Peroxidase, superoxide dismutase, and catalase activity, as well as glutathione status, were ...
Changes in activities of antioxidant enzymes during Chenopodium murale seed germination
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2008)
The activities and isoenzyme pattern of catalase (CAT), superoxide dismutase (SOD) and peroxidase (POD) have been studied during germination of Chenopodium murale seeds. CAT and SOD activities were similar in dry seeds and ...
Changes in antioxidative enzymes activities during Tacitus bellus direct shoot organogenesis
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2012)
Changes in antioxidative enzymes activities during Tacitus bellus direct shoot organogenesis from leaf explants were examined. During the early stages of shoot organogenesis there was a decrease in superoxide dismutase ...
