The relationship between metal toxicity and cellular redox imbalance
TL;DR: Analysis of plants expressing targeted modifications of components of the antioxidant system and comparison of closely related plant species with different degrees of toxic metal sensitivity have established a link between the degree of plant tolerance to metals and the level of antioxidants.

Hydrogen Peroxide is Scavenged by Ascorbate-specific Peroxidase in Spinach Chloroplasts
Yoshiyuki Nakano,Kozi Asada +1 more
TL;DR: Observations confirm that the electron donor for the scavenging of hydrogen peroxide in chloroplasts is L-ascorbate and that the L-ASCorbate is regenerated from DHA by the system: photosystem I-*ferredoxin-*NADP^>glutathione and a preliminary characterization of the chloroplast peroxidase is given.
