Role of Apoplastic and Cell-Wall Peroxidases on the Stimulation of Root Elongation by Ascorbate.

Plant physiology

Cordoba-Pedregosa M, Gonzalez-Reyes JA, Canadillas M, Navas P, Cordoba F.
PMID: 12226436
Plant Physiol. 1996 Nov;112(3):1119-1125. doi: 10.1104/pp.112.3.1119.

Elongation of onion (Allium cepa L.) roots was highly stimulated by ascorbate (ASC) and its natural precursor I-galactone-[gamma]-lactone (GL). When incubation media were supplemented with lycorine (Lyc), an inhibitor of the ASC biosynthesis, root growth was negligible even in...

Abolition of an Inducible Highly Anionic Peroxidase Activity in Transgenic Tomato.

Plant physiology

Sherf BA, Bajar AM, Kolattukudy PE.
PMID: 12231677
Plant Physiol. 1993 Jan;101(1):201-208. doi: 10.1104/pp.101.1.201.

Locally induced expression of a highly anionic peroxidase has previously been correlated temporally and spatially with suberization of tissues responding to pathogen assault, wounding, or exogenously applied abscisic acid or fungal elicitors. DNA sequences corresponding to the 5[prime] regions...

Solubilization and Separation of a Plant Plasma Membrane NADPH-O2- Synthase from Other NAD(P)H Oxidoreductases.

Plant physiology

Van Gestelen P, Asard H, Caubergs RJ.
PMID: 12223822
Plant Physiol. 1997 Oct;115(2):543-550. doi: 10.1104/pp.115.2.543.

Solubilization and ion-exchange chromatography of plasma membrane proteins obtained from bean (Phaseolus vulgaris L.) seedlings resulted in a single NAD(P)H-O2--synthase protein peak. This enzyme showed a high preference toward NADPH as a substrate (reaction rate, 27.4 nmol O2- produced...

Biodegradation of superabsorbent polymers in soil.

Environmental science and pollution research international

Stahl JD, Cameron MD, Haselbach J, Aust SD.
PMID: 19009427
Environ Sci Pollut Res Int. 2000;7(2):83-8. doi: 10.1065/espr199912.014.

Biodegradation of two superabsorbent polymers, a crosslinked, insoluble polyacrylate and an insoluble polyacrylate/ polyacrylamide copolymer, in soil by the white-rot fungus, Phanerochaete chrysosporium was investigated. The polymers were both solubilized and mineralized by the fungus but solubilization and mineralization...

Rapid Accumulation of Anionic Peroxidases and Phenolic Polymers in Soybean Cotyledon Tissues following Treatment with Phytophthora megasperma f. sp. Glycinea Wall Glucan.

Plant physiology

Graham MY, Graham TL.
PMID: 16668570
Plant Physiol. 1991 Dec;97(4):1445-55. doi: 10.1104/pp.97.4.1445.

Phytophthora megasperma Drechs. f. sp. glycinea Kuan & Erwin (PMG) cell wall glucan has been extensively characterized as an elicitor of the pterocarpan phytoalexins, the glyceollins in soybean (Glycine max L.). Just recently, this glucan was shown to be...

The Effect of Pseudomonas putida Colonization on Root Surface Peroxidase.

Plant physiology

Albert F, Anderson AJ.
PMID: 16665732
Plant Physiol. 1987 Oct;85(2):537-41. doi: 10.1104/pp.85.2.537.

Increased activities of peroxidase and indole 3-acetic acid (IAA) oxidase were detected on root surfaces of bean (Phaseolus vulgaris) seedlings colonized with a soil saprophytic bacterium, Pseudomonas putida. IAA oxidase activity increased over 250-fold and peroxidase 8-fold. Enhancement was...

Purification and Characterization of Isoperoxidases Elicited by Aspergillus flavus in Cotton Ovule Cultures.

Plant physiology

Mellon JE.
PMID: 16667941
Plant Physiol. 1991 Jan;95(1):14-20. doi: 10.1104/pp.95.1.14.

Two anionic isoperoxidases were isolated from media of Aspergillus flavus-inoculated cotton (Gossypium hirsutum L.) ovule cultures and purified about 150-fold to apparent homogeneity by treatment with Cell Debris Remover and ion exchange chromatography on Accell QMA medium. These isoperoxidases...

Peroxidases in Tobacco Abscission Zone Tissue: II. Time Course Studies of Peroxidase Activity during Ethylene-induced Abscission.

PMID: 16658858
Plant Physiol. 1974 Aug;54(2):192-6. doi: 10.1104/pp.54.2.192.

Ethylene-induced abscission in flower pedicels of Nicotiana tabacum L. cv. Little Turkish causes a progressive increase in peroxidase activity during the first 4 hours of a 5-hour time course ethylene treatment period, with decrease in peroxidase activity occurring between...

Soluble and cell wall peroxidases in reed canarygrass in relation to disease resistance and localized lignin formation.

Plant physiology

Vance CP, Anderson JO, Sherwood RT.
PMID: 16659599
Plant Physiol. 1976 Jun;57(6):920-2. doi: 10.1104/pp.57.6.920.

The relationship of peroxidases to an inducible disease-resistance mechanism involving lignification of leaf epidermal cell walls was studied. Reed canarygrass (Phalaris arundinacea L.) leaf discs were inoculated with Helminthosporium avenae Eidam and floated on water. In inoculated discs, the...

Peroxidase Release Induced by Ozone in Sedum album Leaves: Involvement of Ca.

Plant physiology

Castillo FJ, Penel C, Greppin H.
PMID: 16663520
Plant Physiol. 1984 Apr;74(4):846-51. doi: 10.1104/pp.74.4.846.

The effect of ozone was studied on the peroxidase activity from various compartments of Sedum album leaves (epidermis, intercellular fluid, residual cell material, and total cell material). The greatest increase following a 2-hour ozone exposure (0.4 microliters O(3) per...
