“…AA is influenced by the degree of maturity of the fruit [12], temperature, and radiation [13]. SNP is widely used as a NO donor in plants to study the effects of NO [38]; when implemented in low quantities, SNP acts as an intra-and intercellular messenger involved in the regulation of various biochemical processes [39] and increases AA in vitro [40,41] as well as the levels of some BCs [42]. Based on our results, significant differences were found in AA for the NO applications in truss five relative to the other treatments, except the control.…”

The tomato fruit is rich in bioactive compounds with antioxidant activity, the levels of which can vary over time in response to biotic and abiotic factors, including the application of elicitors. We investigated the effects of foliar spray of methyl jasmonate (MeJ), salicylic acid (SA), nitric oxide (NO), and hydrogen peroxide (H 2 O 2 ) on tomato plants every 15 days until the end of cultivation. We measured the levels of bioactive compounds, antioxidant activity, and physiological parameters in three distinct trusses. With the exception of plant length, the elicitors had no effects on physiological parameters, whereas they did have an effect on lycopene content, bioactive compound levels, and antioxidant activity in the three sampled trusses. A strong correlation between bioactive compounds and antioxidant activity was found for the elicitors, particularly MeJ. Our results indicate that certain bioactive compounds and their antioxidant activities vary not only between trusses but also based on the specific elicitor used.

“…Soybean plants incubated with SNP prior to salt stress exhibited higher relative water content (RWC) than salt-stressed plants devoid of NO treatment (Dinler et al 2014). Exogenous NO also stimulated proline accumulation in several plant species Zeng et al 2011;Hayat et al 2012;Khan et al 2012;Fan et al 2013;Liu et al 2013). The activity of pyrroline-5-carboxylate synthetase and proline dehydrogenase, enzymes involved in L-proline biosynthesis, and L-proline accumulation were boosted by SNP in cucumber seedlings under high salinity (Fan et al 2013).…”

High salinity aff ects plants due to stimulation of osmotic stress. Cell signaling triggered by nitric oxide (NO) and hydrogen sulfi de (H 2 S) activates a cascade of biochemical events that culminate in plant tolerance to abiotic and biotic stresses. For instance, the NO/H 2 S-stimulated biochemical events that occur in plants during response to high salinity include the control of reactive oxygen species, activation of antioxidant system, accumulation of osmoprotectants in cytosol, induction of K + uptake and Na + cell extrusion or its vacuolar compartmentation among others. Th is review is a compilation of what we have learned in the last 10 years about NO participation during cell signaling in response to high salinity as well as the role of H 2 S, a new player in the mechanism of plant tolerance to salt stress. Th e main sources of NO and H 2 S in plant cells is also discussed together with the evidence of interplay between both signaling molecules during response to stress.

“…Exogenous application of NO increases tolerance to salinity by inducing the activities of antioxidative enzymes in Citrus aurantium L. (Tanou et al 2012) and tomato (Hayat et al 2012). Besides, enhancing the activities of antioxidative enzymes, NO also protects plants from salinity by boosting the contents of antioxidant metabolites, e.g.…”

Nitric Oxide Action in Abiotic Stress Responses in Plants

View full text Add to dashboard Cite

Nitric oxide (NO), a free radical in living organisms, is considered a phytohormone and a key signalling molecule functioning in various physiological processes of plants. These physiological processes include germination, growth, senescence, and photosynthesis as well as response mechanisms to specific environmental stresses. Plants under abiotic stress conditions experience oxidative and nitrosative stress; the latter mainly elicited by regulation of NO production. Nitrosative stress describes the molecular or cellular damage promoted by imbalance in NO homeostasis and other reactive nitrogen species. Additionally, depending on its concentration and location in plant cells or tissues, NO might function as an antioxidant and scavenge some other reactive intermediates. Direct or indirect involvement of NO in response mechanisms under water stress, drought, salinity, heavy metal stress, high or low temperature extremities, and ultraviolet radiation has been reported. In this work, the recent findings and current knowledge on the function of NO in plants under abiotic stress conditions are reviewed briefly.
