Achieving abiotic stress tolerance in plants through antioxidative defense mechanisms
TL;DR: In this paper , the authors discuss various antioxidative defense approaches used to improve abiotic stress tolerance in plants and the mechanism of action of the genes or enzymes involved, and discuss the effect of environmental stress on plants.

Plant Glutathione Transferases and Their Role in the Mitigation of Abiotic Stresses
TL;DR: GSTs play an important role in alleviating oxidative stress from plants including H2O2 content, reactive oxygen species, and methylglyoxal, etc as discussed by the authors , and GSTs being hydrophilic, highly reactive and stable compound effectively scavenges ROS by inhibiting oxidation of thiol (SH) group and creating redox buffer that aids in the stabilization of cellular redox state while heavy metals detoxify by binding with thiol group and decreased concentration of metals in cytosol.

Oxidant and antioxidant signalling in plants: a re-evaluation of the concept of oxidative stress in a physiological context
Christine H. Foyer,Graham Noctor +1 more
TL;DR: It is proposed that the oxidative stress syndrome would be more usefully described as 'oxidative signalling', that is, an important and critical function associated with the mechanisms by which plant cells sense the environment and make appropriate adjustments to gene expression, metabolism and physiology.

Glutathione in plants: an integrated overview.
Graham Noctor,Amna Mhamdi,Sejir Chaouch,Yi Han,Jenny Neukermans,Belén Márquez-García,Guillaume Queval,Christine H. Foyer +7 more
TL;DR: How alterations in glutathione status, such as those observed during stress, may participate in signal transduction cascades are discussed and how these alterations are integrated to fine-tune photorespiratory and respiratory metabolism and to modulate phytohormone signalling pathways.
Journal ArticleDOI
Biotechnological approach of improving plant salt tolerance using antioxidants as markers.
TL;DR: The role of different antioxidants as potential selection criteria for improving plant salt tolerance has been critically discussed and the potential of this approach in counteracting stress-induced oxidative stress has been discussed at length in this review.
