Exogenous low-dose hydrogen peroxide enhances drought tolerance of soybean (Glycine max L.) through inducing antioxidant system [PDF]

, 2016
Hydrogen peroxide (H2O2) functions as a signal molecule in plants under abiotic and biotic stress. In this study, the role of exogenous H2O2 in improving drought tolerance in two soybean cultivars (Glycine max L.

Hyperpolarized 13C Spectroscopic Evaluation of Oxidative Stress in a Rodent Model of Steatohepatitis. [PDF]

, 2017
Nonalcoholic fatty liver disease (NAFLD) has become highly prevalent, now considered the most common liver disease in the western world. Approximately one-third of patients with NASH develop non-alchoholic steatohepatitis (NASH), histologically defined ...

Distribution and Functions of Monodehydroascorbate Reductases in Plants: Comprehensive Reverse Genetic Analysis of Arabidopsis thaliana Enzymes

Antioxidants, 2021
Monodehydroascorbate reductase (MDAR) is an enzyme involved in ascorbate recycling. Arabidopsis thaliana has five MDAR genes that encode two cytosolic, one cytosolic/peroxisomal, one peroxisomal membrane-attached, and one chloroplastic/mitochondrial ...

Existing antioxidant levels are more important in acclimation to supplemental UV-B irradiation than inducible ones: Studies with high light pretreated tobacco leaves [PDF]

, 2012
Greenhouse grown tobacco plants were exposed to supplemental ultraviolet irradiation (280-400 nm, UV-B centered) for 6 days and changes in their photosynthesis (gas exchange and electron transport) and general and specific antioxidant activities were ...

Improving photosynthesis and the ascorbate-glutathione cycle of own-root and grafted-root chrysanthemums by brassinolide under drought stress

Horticultural Science
Many studies have demonstrated that brassinolide improves the drought tolerance of plants. This study aims to test whether the drought tolerance of chrysanthemums can be improved by brassinolide and to clarify the underlying physiological mechanism.

Acinetobacter calcoaceticus CSY-P13 Mitigates Stress of Ferulic and p-Hydroxybenzoic Acids in Cucumber by Affecting Antioxidant Enzyme Activity and Soil Bacterial Community

Frontiers in Microbiology, 2018
Ferulic acid (FA) and p-hydroxybenzoic acid (PHBA) are main phenolic compounds accumulated in rhizosphere of continuously cropped cucumber, causing stress in plants. Microbial degradation of a mixture of FA and PHBA is not well understood in soil.

Antioxidant Systems are Regulated by Nitric Oxide-Mediated Post-translational Modifications (NO-PTMs) [PDF]

, 2016
Nitric oxide (NO) is a biological messenger that orchestrates a plethora of plant functions, mainly through post-translational modifications (PTMs) such as S-nitrosylation or tyrosine nitration.

The pivotal function of dehydroascorbate reductase in glutathione homeostasis in plants [PDF]

Journal of Experimental Botany, 2020
Abstract Under natural conditions, plants are exposed to various abiotic and biotic stresses that trigger rapid changes in the production and removal of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2). The ascorbate-glutathione pathway has been recognized to be a key player in H2O2 metabolism, in which reduced glutathione (

Jasmonates enhance plants tolerance grown in Cd‐contaminated environments: A comprehensive overview

Annals of Applied Biology, EarlyView.
Jasmonates (JAs) enhance plant tolerance to cadmium (Cd) stress by activating antioxidant defences but may reduce Cd uptake, limiting their effectiveness for phytoremediation. This review compiles studies that evaluated the effects of JA application on plants grown in Cd‐contaminated environments. Abstract Cadmium (Cd) is a toxic heavy metal and one of

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

The FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.
