“…It is often claimed that besides NAD(P)H oxidases, also peroxidases can serve as a source for apoplastic O 2 Á-production in vivo (e.g., Bolwell et al 2002;Minibayeva et al 2009). However, peroxidases exhibit O 2 Á--producing activity only if artificially supplied with an electron donor such as NAD(P)H at high concentrations (Chen and Schopfer 1999).…”

Production of reactive oxygen species (hydroxyl radicals, superoxide radicals and hydrogen peroxide) was studied using EPR spin-trapping techniques and specific dyes in isolated plasma membranes from the growing and the non-growing zones of hypocotyls and roots of etiolated soybean seedlings as well as coleoptiles and roots of etiolated maize seedlings. NAD(P)H mediated the production of superoxide in all plasma membrane samples. Hydroxyl radicals were only produced by the membranes of the hypocotyl growing zone when a Fenton catalyst (FeEDTA) was present. By contrast, in membranes from other parts of the seedlings a low rate of spontaneous hydroxyl radical formation was observed due to the presence of small amounts of tightly bound peroxidase. It is concluded that apoplastic hydroxyl radical generation depends fully, or for the most part, on peroxidase localized in the cell wall. In soybean plasma membranes from the growing zone of the hypocotyl pharmacological tests showed that the superoxide production could potentially be attributed to the action of at least two enzymes, an NADPH oxidase and, in the presence of menadione, a quinone reductase.

“…in addition, they found that this type ii Prx has a remarkable glutathione peroxidase activity. Plant peroxidases secreted into the apoplast are an important class of enzymes responsible for the stress-induced formation and degradation of RoS (14,35). We suppose that the peroxiredoxin identified in the present study may help to eliminate cell-toxic peroxides accumulated in the extracellular space upon UV-B exposure of Synechocystis.…”

“…4) than the control. Other studies have shown plants exposed to significant levels of stress to produce high levels of H 2 O 2 within their tissue (Valavanidis et al 2006;Minibayeva et al 2009). In the present study, H 2 O 2 production was also significantly negatively correlated with distance from the source suggesting that leaf H 2 O 2 production may represent a suitable biomarker of air pollution in B. discolor.…”

Bioindicators are useful in monitoring air pollution. This study assessed the efficacy of various tree leaf morphological, physiological and biochemical biomarkers in reflecting different intensities of air pollution. Leaves from Brachylaena discolor trees growing 0, 2.5, 6 and 11 km from an industrial hub (pollution source) in eThekwini, South Africa, were analysed for leaf area, chlorophyll (Chl) content, superoxide and hydrogen peroxide (H 2 O 2 ) production, electrolyte leakage, total antioxidant activity and concentration of selected minerals. B. discolor saplings grown under greenhouse conditions served as an ex situ control. Surface SO 2 and NO x levels which were measured at the in situ and control sites declined significantly with increasing distance from the source but were below detectable limits at the control site. At the site closest to the source, leaf area was significantly lower and Chl, electrolyte leakage, and copper (Cu) and phosphorous (P) levels were significantly higher than the control. Leaf area was significantly positively, and Chl content significantly negatively, correlated with distance from the source, while H 2 O 2 production, electrolyte leakage and Cu and P concentrations were all significantly negatively correlated with distance from the source. The aforementioned parameters represent potential biomarkers of air pollution in B. discolor and in some cases (e.g., H 2 O 2 and electrolyte leakage; leaf area and leaf Chl content) should be measured in conjunction with each other to accommodate for interactive effects. Using B. discolor leaves as bioindicators of air pollution may represent a more viable option for monitoring air pollution than monitoring stations.
