TLDR
It is indicated that a toxic concentration of copper (50 μM) induces oxidative stress and differential responses of antioxidant enzymes in plant parts and that GPX activity increased in response to damage.About:

Plant responses to abiotic stresses: heavy metal‐induced oxidative stress and protection by mycorrhization
TL;DR: The present results indicate that mycorrhization stimulated the phenolic defence system in the Paxillus-Pinus mycorRhizal symbiosis and Plants in certain mycor rhizal associations are less sensitive to cadmium stress than non-mycorrhizal plants.

Antioxidative parameters in the seedlings of pigeonpea (Cajanus cajan (L.) Millspaugh) in response to Zn and Ni stresses.
K.V Madhava Rao,T.V.S Sresty +1 more
TL;DR: Correlation coefficients between the different antioxidant parameters and metal dose level, or dry matter accumulation, were established, assessing for an induced-oxidative stress and comparing the sensitivity of the two cultivars.

Biological effects of heavy metals: an overview.
TL;DR: Heavy metals constitute a very heterogeneous group of elements widely varied in their chemical properties and biological functions and cause reductions in plant growth, dry matter accumulation and yield.

Mercury-induced oxidative stress in tomato seedlings.
Un-Haing Cho,Jung-O Park +1 more
TL;DR: The results suggest that the phytotoxic effects of Hg in tomato seedlings may be achieved by an enhanced production of active oxygen species (AOS) and subsequent lipid peroxidation.

Copper toxicity in Ceratophyllum demersum L. (Coontail), a free floating macrophyte: response of antioxidant enzymes and antioxidants
TL;DR: Copper-induced oxidative stress, response of antioxidative enzymes and substances were investigated in Ceratophyllum demersum L. (Coontail), a free floating macrophyte to understand the mechanisms of Cu resistance and the level of tolerance depends on the antioxidative capacity of the plants.

A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding
TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.

Microsomal lipid peroxidation.
John A. Buege,Steven D. Aust +1 more
TL;DR: This chapter discusses microsomal lipid peroxidation, a complex process known to occur in both plants and animals that involves the formation and propagation of lipid radicals, the uptake of oxygen, a rearrangement of the double bonds in unsaturated lipids, and the eventual destruction of membrane lipids.
