Nitrogen source influences the antioxidative system of soybean plants under hypoxia and re-oxygenation

Scientia Agricola
: In this work, we compared nitrate-supplied plants (non-nodulated) with non-nitrate-supplied plants (nodulated) under oxygen privation of root system (hypoxia) and re-oxygenation (post-hypoxia; recovery) in order to verify whether N sources affect the ...

Changes in ascorbate peroxidase activity during the root development of Raphanus sativus L.

, 1994
P(論文)Relatively high levels of ascorbic acid content and ascorbate peroxidase activity exist in higher plants and it has been found to be of interest for their physiological roles in detoxification of H_2O_2 inevitably produced from superoxide radicals ...

Copper accumulation, synthesis of ascorbate and activation of ascorbate peroxidase in Enteromorpha compressa (L.) Grev. (Chlorophyta) from heavy metal-enriched environments in northern Chile

, 2003
Enteromorpha compressa is the dominant species in coastal areas of northern Chile receiving copper mine wastes. Copper remains as the main heavy metal in these coastal waters and it is accumulated in E. compressa growing at the impacted sites. Algae from

Inhibition of ascorbate peroxidase under oxidative stress in tobacco having bacterial catalase in chloroplasts

, 1998
To analyze the potential of the active oxygen-scavenging system of chloroplasts, we introduced Escherichia coli catalase into tobacco chloroplasts. Photosynthesis of transgenic plants was tolerant to high irradiance under drought conditions, while the ...

Engineering the Substrate Specificity and Reactivity of a Heme Protein: Creation of an Ascorbate Binding Site in Cytochrome c Peroxidase

, 2016
The binding of substrates to heme enzymes has been widely assumed to occur at the so-called δ-heme edge. Recently, however, a number of examples have appeared in which substrate binding at an alternative site, the γ-heme edge, is also possible.
