Metabolic adaptations to arsenic-induced oxidative stress in Pteris vittata L and Pteris ensiformis L
This study examined the metabolic adaptations of Pteris vittata L, an arsenic
hyperaccumulator, under arsenic stress as compared to Pteris ensiformis, a non-arsenic
hyperaccumulator. Both plants were grown hydroponically in 20% Hoagland medium in
controlled conditions and were treated with 0, 133 or 267μM arsenic as sodium arsenate for
1, 5 or 10d. The fern fronds were analysed for differences in oxidative stress and antioxidant
capacities after arsenic exposure. Upon exposure to 133μM arsenic, concentrations of …
