Friend or foe? Reactive oxygen species production, scavenging and signaling in plant response to environmental stresses
Over the past two decades it has been proven that ROS together with non‐photochemical quenching (NPQ), hormones, Ca2+ waves, and electrical signals are the main players in SAA and SAR, two physiological processes essential for plant survival and productivity in unfavorable conditions. Expand
ACC deaminase containing endophytic bacteria ameliorate salt stress in Pisum sativum through reduced oxidative damage and induction of antioxidative defense systems
The induction of endophytic bacterium-induced salt tolerance in pea plants depends primarily on the effect ofendophytic bacteria on osmoregulation, the antioxidant capacity, and ion uptake adjustment by limiting the uptake of Na+ and, alternatively, increasing the accumulation of K+ in plant tissue.

Antioxidant status of medicinal and aromatic plants under the influence of growth-promoting rhizobacteria and osmotic stress
The role of PGPR is elaborated on in helping medicinal and aromatic plants to cope with osmotic stress through antioxidant defenses, and a future research requirement involving investigating the combined utilization of osmosis stress and PGPR in order to enhance the content of secondary metabolites is emphasized.

Knockdown of 60S ribosomal protein L14-2 reveals their potential regulatory roles to enhance drought and salt tolerance in cotton
Background Cotton is a valuable economic crop and the main significant source of natural fiber for textile industries globally. The effects of drought and salt stress pose a challenge to strong fiberExpand
24-Epibrassinolide Positively Modulate Leaf Structures, Antioxidant System and Photosynthetic Machinery in Rice Under Simulated Acid Rain
Acid rain causes significant damage to rice plants, affecting the photosynthetic machinery and growth. 24-epibrassinolide (EBR) is an organic steroid, which, used at low concentrations, positivelyExpand
A Comparative Study On The Adaptability Of The Different Varieties Of Solanum Lycopersicum L. (Tomato) In Salt Stress Condition
The objective of the present study was to study the levels of antioxidant and oxidant metabolites such as total protein, prol ine, peroxidase, lipid peroxidase, catalase,and anthocyanin and phenolExpand
Analysis of Phaseolus vulgaris gene expression related to oxidative stress response under short-term cadmium stress and relationship to cellular H2O2
In this study, we aimed to investigate the changes in the malondialdehyde (MDA) content and cellular H2O2 accumulation, which are the oxidative stress markers, and the expression levels ofExpand
Biochemical and Molecular Mechanisms of Abiotic Stress Tolerance
In the given chapter, plant molecular and biochemical responses have been reviewed and discussed with respect to various crop plants to impart better understanding of tolerance mechanisms under abiotic stress. Expand
Bioregulators: unlocking their potential role in regulation of the plant oxidative defense system
A new line of evidence is summarized that how PBRs act as inducers of oxidative stress resistance in plants and how they could be modulated in transgenic crops via introgression of genes is summarized. Expand
