The effect of NADPH oxidase inhibitor diphenyleneiodonium (DPI) and glutathione (GSH) on Isatis cappadocica, under Arsenic (As) toxicity
TL;DR: In this paper, the effects of arsenic (As, 1000 µm), diphenyleneiodonium (DPI, 10 µm) and reduced glutathione (GSH, 500 µm)) on Isatis cappadocica were assessed.
Journal ArticleDOI
Overexpression of β-cyanoalanine synthase of Prunus persica increases salt tolerance by modulating ROS metabolism and ion homeostasis
TL;DR: In this article, the identification and functional characterization of β-cyanoalanine synthase (β-CAS) isolated from peach (Prunus persica) was reported. And the results demonstrate that PpCAS1 positively regulates salt tolerance in peach plants through the modulation of reactive oxygen species (ROS) and ion homeostasis.

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.

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.
