Journal ArticleDOI
Tolerance of pea (Pisum sativum L.) to long‐term salt stress is associated with induction of antioxidant defences
TL;DR: The data strongly suggest that induction of antioxidant defences is at least one component of the tolerance mechanism of peas to long-term salt-stress.
Journal ArticleDOI
Evidence for the Presence of the Ascorbate-Glutathione Cycle in Mitochondria and Peroxisomes of Pea Leaves
TL;DR: The ascorbate-glutathione cycle of mitochondria and peroxisomes could represent an important antioxidant protection system against H2O2 generated in both plant organelles.
Journal ArticleDOI
Antioxidant systems and o2.?/h2o2 production in the apoplast of pea leaves. its relation with salt-induced necrotic lesions in minor veins
TL;DR: The results suggest a strong interaction between both cell compartments in the control of the apoplastic ASC content in pea leaves, but this anti-oxidative response does not seem to be sufficient to remove the harmful effects of high salinity.
Journal ArticleDOI
Changes in oxidative processes and components of the antioxidant system during tomato fruit ripening.

TL;DR: Changes in the activities of superoxide dismutase, catalase and the enzymes involved in the ascorbate-glutathione cycle during ripening indicated that the antioxidative system plays a fundamental role in the ripening of tomato fruits.
Journal ArticleDOI

TL;DR: The mutant regulator of APX2 1-1 (rax1-1) was identified in Arabidopsis thaliana that constitutively expressed normally photooxidative stress-inducible ASCORBATE PEROXIDASE2 (APX2) and had ≥50% lowered foliar glutathione levels, suggesting that changes in glutATHione metabolism may be one means of integrating the function of several signaling pathways.
