Hydrogen Peroxide 154-162 peroxidase N1 Nicotiana tabacum 218-228 17993545-7 2008 The role played by ZmPAO-derived H(2)O(2) production in peroxidase-mediated wall stiffening events was further investigated by exploiting the in vivo use of N-prenylagmatine (G3), a selective and powerful ZmPAO inhibitor, representing a reliable diagnostic tool in discriminating ZmPAO-mediated H(2)O(2) production from that generated by peroxidase, oxalate oxidase, or by NADPH oxidase activity. Hydrogen Peroxide 33-41 peroxidase N1 Nicotiana tabacum 56-66 19704660-3 2008 Indeed, H(2)O(2) is the co-substrate for the peroxidase-driven reactions during cell-wall maturation and a key signalling molecule in defence mechanisms. Hydrogen Peroxide 8-16 peroxidase N1 Nicotiana tabacum 45-55 16817898-0 2006 An inserted loop region of stromal ascorbate peroxidase is involved in its hydrogen peroxide-mediated inactivation. Hydrogen Peroxide 75-92 peroxidase N1 Nicotiana tabacum 45-55 16817898-1 2006 Ascorbate peroxidase isoforms localized in the stroma and thylakoid of higher plant chloroplasts are rapidly inactivated by hydrogen peroxide if the second substrate, ascorbate, is depleted. Hydrogen Peroxide 124-141 peroxidase N1 Nicotiana tabacum 10-20 16817898-6 2006 A chimeric ascorbate peroxidase B with this sequence inserted was inactivated by hydrogen peroxide within a few minutes. Hydrogen Peroxide 81-98 peroxidase N1 Nicotiana tabacum 21-31 16181612-3 2005 We here studied the roles of the oxidative stress-responsive putative voltage-dependent Ca(2+) permeable channels, NtTPC1A and NtTPC1B, and cell cycle in H(2)O(2)-induced expression of antioxidant enzymes, glutathione peroxidase (GPX) and ascorbate peroxidase (APX), in tobacco BY-2 cells. Hydrogen Peroxide 154-162 peroxidase N1 Nicotiana tabacum 249-259 12929422-3 2003 Peroxidase/H2O2-mediated radical coupling of 4-hydroxycinnamaldehydes produces 8-O-4-, 8-5-, and 8-8-coupled dehydrodimers as has been documented earlier, as well as the 5-5-coupled dehydrodimer. Hydrogen Peroxide 11-15 peroxidase N1 Nicotiana tabacum 0-10 12966073-1 2003 Ascorbate peroxidase (APX) is a heme-containing protein that plays a central role in scavenging H(2)O(2) in higher plants. Hydrogen Peroxide 96-104 peroxidase N1 Nicotiana tabacum 10-20 12675745-1 2003 In higher plants, ascorbate peroxidase (APX; EC 1.11.1.11), the major H2O2-scavenging enzyme, occurs in several distinct isoenzymes that are localized in cytosol and various cell organelles. Hydrogen Peroxide 70-74 peroxidase N1 Nicotiana tabacum 28-38 10938860-5 2000 The results showed that SA induced the peroxidase inhibitor-sensitive production of superoxide and H2O2 in tobacco suspension culture, but no production of hydroxy radicals was detected. Hydrogen Peroxide 99-103 peroxidase N1 Nicotiana tabacum 39-49 10938860-8 2000 The results suggest that SA protect the cells from highly reactive hydroxy radicals, while producing the less reactive superoxide and H2O2 through peroxidase-catalysed reaction, as the intermediate signals. Hydrogen Peroxide 134-138 peroxidase N1 Nicotiana tabacum 147-157 24226068-4 1987 Study of the mechanism of insolubilisation of tyramine showed that the amine was integrated in regions in which peroxidase activity could be located cytochemically using 3,3"-diaminobenzidine and H2O2 as substrates. Hydrogen Peroxide 196-200 peroxidase N1 Nicotiana tabacum 112-122 10366970-5 1999 The activation of tobacco peroxidase (in presence of Ca(2+)-cations and without them) and of recombinant horseradish peroxidase (in presence of H2O2) by gamma-irradiation was really observed (respect to guaiacol as substrate). Hydrogen Peroxide 144-148 peroxidase N1 Nicotiana tabacum 117-127 9305623-7 1997 Alternative H2O2-scavenging mechanisms may have compensated for reduced catalase activity, as shown by increased ascorbate peroxidase and glutathione peroxidase levels. Hydrogen Peroxide 12-16 peroxidase N1 Nicotiana tabacum 123-133 12226176-5 1996 Surprisingly, the regenerative potentiality in dividing protoplasts was specifically correlated with a higher NADH-peroxidase activity, which resulted in a net H2O2 accumulation in the cells. Hydrogen Peroxide 160-164 peroxidase N1 Nicotiana tabacum 115-125 24311170-0 1980 The role of peroxidase isoenzyme groups of Nicotiana tabacum in hydrogen peroxide formation. Hydrogen Peroxide 64-81 peroxidase N1 Nicotiana tabacum 12-22 16662626-0 1982 Role of peroxidase in lignification of tobacco cells : I. Oxidation of nicotinamide adenine dinucleotide and formation of hydrogen peroxide by cell wall peroxidases. Hydrogen Peroxide 122-139 peroxidase N1 Nicotiana tabacum 8-18 16662627-2 1982 Coniferyl alcohol is the primary substrate for peroxidase-mediated lignification, a process which depends on the generation of H(2)O(2) by NADH oxidation. Hydrogen Peroxide 127-135 peroxidase N1 Nicotiana tabacum 47-57 24311170-1 1980 Three peroxidase isoenzyme-groups found in cell walls of tobacco were tested for their capacity to form H2O2. Hydrogen Peroxide 104-108 peroxidase N1 Nicotiana tabacum 6-16 24311170-5 1980 These facts indicate that each of the peroxidase isoenzyme groups of the cell wall is involved with different catalytic functions within the same pathways of H2O2-formation and succeeding lignification. Hydrogen Peroxide 158-162 peroxidase N1 Nicotiana tabacum 38-48 33948972-8 2021 Plant responses to the pre-treatment were notably different: (1) H2 O2 increased the activity of catalase (CAT, EC 1.11.1.6), phenylalanine ammonia lyase (PAL; EC 4.3.1.5) and peroxidase activities (POD, EC 1.11.1.7), and (2) the combined treatment induced epidermal flavonols which were key to drought tolerance.
