Mechanical wounding is a common stress caused by herbivores or manual and natural manipulations, whereas its roles in acclimation response to a wide spectrum of abiotic stresses remain unclear. The present work showed that local mechanical wounding enhanced freezing tolerance in untreated systemic leaves of wheat plants (Triticum aestivum L.), and meanwhile the signal molecules hydrogen peroxide (H2O2) and nitric oxide (NO) were accumulated systemically. Pharmacological study showed that…

The Role of Hydrogen Peroxide in Mediating the Mechanical Wounding-Induced Freezing Tolerance in Wheat
TLDR
Results support the hypothesis that local mechanical wounding-induced SWR in newly occurred leaves is largely attributed to RBOH-dependent H2O2 production, which may subsequently induce freezing tolerance in wheat plants and have a potential application to reduce the yield losses of wheat under late spring freezing conditions.
Hydrogen Peroxide and Abscisic Acid Mediate Salicylic Acid-Induced Freezing Tolerance in Wheat
TLDR
It is demonstrated that endogenous H2O2 and ABA signaling may form a positive feedback loop to mediate SA-induced freezing tolerance in wheat.

Reactive Oxygen Species Generation, Scavenging and Signaling in Plant Defense Responses
TLDR
This present chapter provides an update on ROS generation, scavenging, and redox signaling in the context of plant abiotic stress tolerance, and identification and characterization of new targets and key regulator ROS-signaling transduction pathways which may provide excellent future candidates for breeding/engineering stress-resilient crop plants.
The Exogenous Application of Brassinosteroids Confers Tolerance to Heat Stress by Increasing Antioxidant Capacity in Soybeans
Heat stress is an important factor affecting soybean yield. Brassinosteroids (BRs) play a crucial role in plant growth, development, and defense. In the present study, the regulatory effects of…
Insights Into the Nitric Oxide Mediated Stress Tolerance in Plants
Resistance of Fritillaria imperialis to freezing stress through gene expression, osmotic adjustment and antioxidants
TLDR
The findings suggest that Fritillaria efficiently tolerated freezing stress through induction of signalling mechanisms and overexpression of cold stress-responsive genes, and prevention of cold-induced water stress, oxidative stress and photosynthetic damage.
Priming With the Green Leaf Volatile (Z)-3-Hexeny-1-yl Acetate Enhances Salinity Stress Tolerance in Peanut (Arachis hypogaea L.) Seedlings
TLDR
Results indicated that the green leaf volatile Z-3-HAC protects peanut seedlings against damage from salinity stress through priming for modifications of photosynthetic apparatus, antioxidant systems, osmoregulation, and root morphology.
Green leaf volatile (Z)-3-hexeny-1-yl acetate reduces salt stress in peanut by affecting photosynthesis and cellular redox homeostasis.
TLDR
The results highlight the importance of Z-3-HAC in protecting peanut seedlings against salt stress by affecting photosynthesis, cellular redox homeostasis, K+ : Na+ homeOSTasis, and phytohormones.
Gene expression and metabolic changes of Momordica charantia L. seedlings in response to low temperature stress
TLDR
The results demonstrated that the Momordica Charantia L. seedlings achieved cold tolerance might be went through mobilization of antioxidant systems, adjustment of the transcription factors and accumulation of osmoregulation substance, which presented meaning information for revealing the anti-cold mechanism.

Hydrogen Peroxide Acts as a Second Messenger for the Induction of Defense Genes in Tomato Plants in Response to Wounding, Systemin, and Methyl Jasmonate
TLDR
The cumulative results suggest that active oxygen species are generated near cell walls of vascular bundle cells by oligogalacturonide fragments produced by wound-inducible polygalacturonase and that the resulting H2O2 acts as a second messenger for the activation of defense genes in mesophyll cells.
Hydrogen peroxide is generated systemically in plant leaves by wounding and systemin via the octadecanoid pathway.

TLDR
The cumulative data suggest that systemic wound signals that induce PG activity and H2O2 are widespread in the plant kingdom and that the response may be associated with the defense of plants against both herbivores and pathogens.
Nitrate reductase-mediated early nitric oxide burst alleviates oxidative damage induced by aluminum through enhancement of antioxidant defenses in roots of wheat (Triticum aestivum).
TLDR
It is suggested that an NR-mediated early NO burst plays an important role in Al resistance of wheat through modulating enhanced antioxidant defense to adapt to Al stress.
Systemic Induction of NO-, Redox-, and cGMP Signaling in the Pumpkin Extrafascicular Phloem upon Local Leaf Wounding
TLDR
Findings suggest that NO-dependent S-nitrosylation turned into peroxynitrite-mediated protein nitration upon a stress-induced redox shift probably involving the accumulation of reactive oxygen species within the cucurbit EFP.
ABA-induced NO generation and stomatal closure in Arabidopsis are dependent on H2 O2 synthesis.
TLDR
Physiological and genetic data demonstrate a strong inter-relationship between ABA, endogenous H2 O2 and NO-induced stomatal closure and in the NADPH oxidase deficient double mutant atrbohD/F, NO synthesis and stomatic closure to ABA are severely reduced, indicating that endogenous H 2 O2 production induced by ABA is required for NO synthesis.
Nitric Reductase-Dependent Nitric Oxide Production Is Involved in Cold Acclimation and Freezing Tolerance in Arabidopsis1[W][OA]
TLDR
NR-dependent NO production plays an important role in cold acclimation-induced increase in freezing tolerance by modulating Pro accumulation in Arabidopsis, and Pharmacological studies using NR inhibitor, NO scavenger, and NO donor showed that NR- dependent NO level was positively correlated with freezing tolerance.
Control of Ascorbate Peroxidase 2 expression by hydrogen peroxide and leaf water status during excess light stress reveals a functional organisation of Arabidopsis leaves.
TLDR
Imaging of chlorophyll fluorescence and the production of reactive oxygen species indicated that APX2 expression followed a localised increase in hydrogen peroxide resulting from photosynthetic electron transport in the bundle sheath cells, and exposure of ABA-insensitive mutants to excess light resulted in reduced levels of APx2 expression and confirmed a role for ABA in the signalling pathway.
Mechanical wounding induces a nitrosative stress by down-regulation of GSNO reductase and an increase in S-nitrosothiols in sunflower (Helianthus annuus) seedlings
TLDR
It is proposed that mechanical wounding triggers the accumulation of SNOs, specifically GSNO, due to a down-regulation of GSNOR activity, while NO2-Tyr increases, and a process of nitrosative stress is induced in sunflower seedlings and SNOs constitute a new wound signal in plants.
Nitric oxide induced by hydrogen peroxide mediates abscisic acid-induced activation of the mitogen-activated protein kinase cascade involved in antioxidant defense in maize leaves.
TLDR
The results suggest that ABA-induced H( 2)O(2) production mediates NO generation, which, in turn, activates MAPK and results in the upregulation in the expression and the activities of antioxidant enzymes in ABA signaling.
Catalase is a sink for H2O2 and is indispensable for stress defence in C3 plants
TLDR
Leaf necrosis correlated with accumulation of oxidized glutathione and a 4‐fold decrease in ascorbate, indicating that catalase is critical for maintaining the redox balance during oxidative stress and may not be limited to peroxisomal H2O2 production.
