“…All the reports claim that increased activities of POD, CAT and APX were observed. Antioxidants of POD, CAT and APX are H 2 O 2 -scavengers in plants (Foyer & Noctor 2000, Pereira et al 2002. The greater activities of these three enzymes in the fronds of fern PCA, than the other plants, suggested that fern PCA was more capable of elimination of excess H 2 O 2 and of remaining in homeostasis (Fig.…”

“…However, peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) are important intrinsic antioxidative enzymes in plant cells. They control the H 2 O 2 levels through degradation of unnecessary H 2 O 2 to harmless H 2 O (Foyer & Noctor 2000, Pereira et al 2002. Whether the exposure of Sb may induce oxidative stress in Asaccumulating plants, and whether such plants are equipped with a more efficient ROS-scavenging system than found in non-As-accumulating plants, are important subjects for further investigation.…”

Antimony (Sb) toxicity and contamination has become a growing concern in recent years. Remediation of Sb contamination using plants may be an effective approach. This study aimed to investigate the potential of antimony (Sb) tolerance and accumulation by plants, as well as to understand the antioxidative responses to Sb. One set of hydroponic trials was set up using four species of fern plants, including Pteris cretica (PCA), Microlepia hancei (MH), Cyrtomium fortunei (CYF) and Cyclosorus dentatus (CYD). Ferns were grown for 2 weeks in nutrient solution containing a medium (5 mg L

“…The homogenate was centrifuged (16,000g) at 4°C for 15 min (Pereira et al 2002). The supernatant was used for the analysis of superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (GPX), ascorbate peroxidase (APX) and glutathione reductase (GR).…”

Seedlings of Camellia sinensis (L.) were grown hydroponically to study the effect of aluminium (Al) on leaf antioxidant defence system and cell ultrastructure. We found that malondialdehyde (MDA) content decreased at 0-0.32 mM Al, but increased significantly at 0.53 mM Al. Like MDA, hydrogen peroxide (H 2 O 2 ) content increased at 0.53 mM Al; however, no differences were observed at 0-0.32 mM Al. Superoxide dismutase (SOD, EC1.15.

“…Superoxide dismutase activity was determined on the gel as described by [42]. The gels were rinsed in water and incubated in the dark for 30 min at room temperature in an assay mixture containing 50 mM potassium phosphate buffer (pH 7.8), 1 mM EDTA, 0.05 mM riboflavin, 0.1 mM nitroblue tetrazolium and 0.3% N,N,N 0 ,N 0 -tetramethylethylenediamine (TEMED).…”
