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…

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 Acts as a Second Messenger for the Induction of Defense Genes in Tomato Plants in Response to Wounding, Systemin, and Methyl Jasmonate

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.

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.

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.

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.

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.

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

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.

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.
