“…For instance, increased expression of the ERF transcription factor in wheat and tobacco conferred improved tolerance to salinity [74,75], whereas enhanced oxidative stress was detected in the ethylene-insensitive (ein3-1) mutant of Arabidopsis exposed to salt stress [76]. Yet, the involvement of ET in salinity responses in halophytes has been scarcely characterized [77,78]. As indicated in our real-time RT-qPCR analysis, ETR1, a gene coding for one of the ET receptors, was strongly and rapidly induced in response to salt ( Figure 5F).…”

Quinoa (Chenopodium quinoa Willd.), a model halophytic crop species, was used to shed light on salt tolerance mechanisms at the transcriptomic level. An RNA-sequencing analysis of genotype R49 at an early vegetative stage was performed by Illumina paired-ends method comparing high salinity and control conditions in a time-course pot experiment. Genome-wide transcriptional salt-induced changes and expression profiling of relevant salt-responsive genes in plants treated or not with 300 mM NaCl were analyzed after 1 h and 5 days. We obtained up to 49 million pairs of short reads with an average length of 101 bp, identifying a total of 2416 differentially expressed genes (DEGs) based on the treatment and time of sampling. In salt-treated vs. control plants, the total number of up-regulated and down-regulated genes was 945 and 1471, respectively. The number of DEGs was higher at 5 days than at 1 h after salt treatment, as reflected in the number of transcription factors, which increased with time. We report a strong transcriptional reprogramming of genes involved in biological processes like oxidation-reduction, response to stress and response to abscisic acid (ABA), and cell wall organization. Transcript analyses by real-time RT- qPCR supported the RNA-seq results and shed light on the contribution of roots and shoots to the overall transcriptional response. In addition, it revealed a time-dependent response in the expression of the analyzed DEGs, including a quick (within 1 h) response for some genes, suggesting a “stress-anticipatory preparedness” in this highly salt-tolerant genotype.

“…Plant growth regulators such as auxins, brassinosteroid, jasmonates and strigolactones play a vital role in connection with the signaling network and the developmental and adaptive phenomena in plants growing under stress [3,26,27]. Salicylic acid (SA), a phenolic growth regulator, fortifies the plant defense against a variety of stresses [28][29][30][31]. Hao et al [32] reported the SA-induced expression of 59 proteins involved in a variety of cell responses and metabolic processes in Cucumis sativus.…”

“…In Arabidopsis, SA application suppressed the adverse impact of salt stress by reducing the K + leakage in root tissues and increasing the activity of H + -ATPase [35], which strengthens the Na + /H + exchanger at the plasma membrane and reduces the Na + accumulation in cytosol [65]. SA treatment also reduces lipid peroxidation and may interact with other plant hormones to enhance plant resistance and/or tolerance to salt stress [29,31,36,37].…”

Background: Soil salinity is considered as one of the major environmental factors that has reduced plant productivity worldwide. This study investigates the impact of salinity on plant growth attributes, biochemical and physiological leaf characteristics in two cultivars (Adet and Merawi) of Brassica carinata and also explores the role of salicylic acid (SA) in mitigating the effect of salt stress. Methods: Four-week-old cultivars were treated with NaCl (50, 100 and 150 mM) and SA (0.5 mM) and watered regularly with 100% field capacity. Thus, they were grown under eight different treatments (T1 = no NaCl, no SA; T2 = 0 mM NaCl with 0.5 mM SA; T3 = 50 mM NaCl without SA; T4 = 50 mM NaCl with 0.5 mM SA; T5 = 100 mM NaCl without SA; T6 = 100 mM NaCl with 0.5 mM SA; T7 = 150 mM NaCl without SA; and T8 = 150 mM NaCl with 0.5 mM SA). Nine-week-old cultivars were sampled for analyzing the growth attributes, plant water status, nitrate reductase activity, proline accumulation, photosynthetic traits, lipid peroxidation level and activity of antioxidant enzymes. Results: Salinity treatments hampered the overall plant growth performance in a dose-dependent manner. Salinity also reduced photosynthetic efficiency by inhibiting chlorophyll synthesis, nitrate reductase activity, chlorophyll fluorescence, stomatal conductance, net photosynthetic and transpiration rates and plant water status. On the other hand, SA application alleviated the adverse effects of salinity and improved the performance of the studied parameters in both the cultivars. Higher dose of salinity increased proline production, but SA application mitigates this impact in both the cultivars studied. The activity of antioxidant enzymes increased under salt stress in a dose-dependent manner. SA treatment to normal or salinity-stressed plants increased the enzymes activity, showing that SA has a crucial role in modulating the cell redox balance and protecting the plants from oxidative damage. SA significantly reduced the salinity-caused effects on the overall performance of plants and their antioxidant systems in both the cultivars. Of the two cultivars, Adet was more tolerant to salinity than Merawi. Conclusions: Foliar application of SA improved the performance of Ethiopian mustard cultivars and mitigated the damage caused by salt stress.

“…In the present study, this is no exception of the fact that Swarna Sub1A may possess the secondary traits for anti-oxidation expression along with suppression of the growth under water. In general, there is a common observation that exogenous application of SA is manifested into total PA pull in plants (33). SA is interacted in a more complex pathway, particularly under stressful condition with other hormonal or growth regulators.…”

Abstract:In the present study, the sensitivity of two chemical elicitors: polyamine (PA) and salicylic (SA) acid were exercised for submergence sensitivity in Swarna Sub1A rice variety. Under 5 days of submergence, the antioxidation responses were more distinguished in plants against control. Along with the anti-oxidation modules, significant changes in biomolecule loss were registered through lipid and protein oxidation by 1.91 and 1.46 -fold respectively. PA and SA treated plants were the reliever to recover the membrane potential. Total carbohydrate and reducing sugars were varied under submergence by down regulation of 36.66 and 44.44% as compared to control. This was also supported by regulation of α-amylase activity under submergence that also recovered significantly with PA and SA treatments against submergence. In association with carbohydrate metabolism, Under submergence Swarna Sub1A recorded to be prone with oxidative stress through O 2. -(1.55 fold) and peroxide (1.70-fold) over-accumulation but recovered as PA and SA applied. In both cases, sustenance of non-enzymatic anti-oxidant like total carotenoid and lycopene content were also contributory through down-regulation. The enzymatic anti-oxidation paths like SOD, GPX, CAT and GR were regulated by 11.11, 19.54, 13.65, 10.03% declined respectively and thoroughly discussed with reference to PA and SA interactions.
