Ectopic expression of SsPETE2, a plastocyanin from Suaeda salsa, improves plant tolerance to oxidative stress.
Xin-Tong Zhou,Fang Wang,Yin-Ping Ma,Li-Jia Jia,Ning Liu,Hai-Yun Wang,Zhao Pan,Gui-Xian Xia,Nai-Qin Zhong +8 more
TL;DR: It is demonstrated that plant PETEs play a novel role in oxidative stress tolerance by regulating Cu homeostasis under stress conditions, and SsPETE2, as an efficient copper-chelating PETE, potentially could be used in crop genetic engineering.

Assessment of phytotoxic effects, uptake and translocation of diclofenac in chicory (Cichorium intybus)
TL;DR: This is the first report on the effect of diclofenac (DCF) on chicory seedlings, including the evaluation of its uptake and translocation, and shows that irrigation with water containing DCF does not represent a threat to human health.
Journal ArticleDOI
Jasmonic acid alleviates cadmium toxicity through regulating the antioxidant response and enhancing the chelation of cadmium in rice (Oryza sativa L.).
TL;DR: In this paper , the role of Jasmonic acid (JA) in mediating rice Cd tolerance was investigated via a fluorescent probe in vivo localization, Fourier Transform Infrared Spectroscopy (FTIR), and colorimetry.

Effects of pomegranate seed oil on oxidant/antioxidant balance in heart and kidney homogenates and mitochondria of diabetic rats and high glucose-treated H9c2 cell line.
Hamid Mollazadeh,Mohammad Taher Boroushaki,Mohammad Soukhtanloo,Amir R Afshari,Mohammad Mahdi Vahedi +4 more
TL;DR: PSO remarkably decreased glucose-induced toxicity, ROS level and lipid peroxidation in H9c2 cells, suggesting that PSO has a protective effect against diabetes-induced alterations in oxidant/antioxidant balance in tissues, mitochondrial and H 9c2 cell line.

Silicon nutrition modulates arsenic-inflicted oxidative overload and thiol metabolism in wheat (Triticum aestivum L.) seedlings.
Palin Sil,Asok K. Biswas +1 more
TL;DR: The antioxidative defense was upregulated and phytochelatin production was lowered causing an appreciable revival from the arsenate-imposed consequences that eventually augmented growth, validate the hypothesis whether silicate may alleviate arsenate -provoked oxidative stress in wheat through diverse metabolic pathways and improve food safety and health.

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.
