“…In accordance with our results, Chunthaburee et al, [63] found that salt stress could promote the antioxidant activities, evaluated by ferric reducing power as well as DPPH-and ABTS-scavenging activity, in the grains of four Oryza sativa cultivars. In a similar trend, the antioxidant potential of three plants, Salsola baryosma, Trianthema triquetra and Zygophyllum simplex, was found to be elevated under salt treatment as indicated by DPPHscavenging activity and the total reducing power [64].…”

The current investigation was conducted to evaluate the potency of salinity to enhance the nutraceutical properties of fenugreek (Trigonella foenum-graecum L.) seedlings. Gradual doses of NaCl solution (0, 50, 100, 150 and 200 mM) were applied and the nutritional value of seedlings was determined 2 and 5 days' post-germination. Moreover, the antioxidant and antimicrobial activity along with the phenolic content of the considered seedlings were assessed. The obtained results manifested that salt application to different levels could increase the amount of protein, N, Zn and Cu in the 2-and 5-day old seedlings. Salinity could also raise the amount of vitamin C, B1, B2 and B9 but only in one stage. Conversely, the amount of reducing, non-reducing and total sugars as well as that of Fe declined under stress. Compared with their unsalted synonyms, water and methanolic extracts of salt-treated fenugreek seedlings had higher H2O2-scavenging activity in the two stages, while their reducing power and free radicles-scavenging activities were promoted in the second stage only. Regarding the antimicrobial activity, water and methanolic extracts of the stressed seedlings generally exhibited better antimicrobial activity against some pathogenic microbes especially Erwinia carotovora, Bacillus subtilis and Candida albicans. Only in the second stage, most of the employed salt concentrations increased the titer of tannins, saponins, alkaloids, flavonoids and total phenols in the aqueous and alcoholic extracts. Therefore, it is recommended to salinize young fenugreek seedlings to improve its health benefits in a simple, lowcost and low-risk approach.

“…A possible reduction in expression of phenolic compounds is due to less availability of the nitrogen and alteration in the activity of related enzymes in plants grown in saline soil (Parmar Rina et al 2017). High amount of phenolic and alkaloid content increased in Achillea fragrantissima, Catharanthus roseus, Oryza sativa, and Solanum nigrum when exposed to salt constrains and these compounds play a crucial role as scavenger (Verma and Shukla 2015;Chunthaburee et al 2015;Ben Abdallah et al 2016). Phenylalanine ammonia lyase (PAL) and CHS (chalcone synthase), hyoscyamine 6β-hydroxylase, tryptophan decarboxylase, and WRKY6 are the key enzymes that regulate shikimic acid, mevalonic, and malonic pathways responsible for synthesis of various secondary metabolites.…”

Studies on plant defense mechanisms in stressful conditions predict that plant cope up with increasing stress for survival. Under environmental stress plants interact with problems like competition and survival under resource constraints or utilization of these resources in production of secondary compounds. In this experiment, we examined the costs of defense by evaluating variation in production of secondary compounds of Brassica nigra grown in the saline (B1 = 100 mM NaCl and B2 = 150 mM NaCl) and control (C = 0 mM) soils and impact of its extracts on weed Anagallis arvensis L. The main allelopathic compounds in Brassica were determined using gas chromatography-mass spectroscopy (GC-MS). The results indicated that A. arvensis was adversely affected by the aqueous extracts of B. nigra. These observations might be related to extracts induced oxidative stress indicated by superoxide (O 2 − ) production through nitroblue tetrazolium, cell integrity by Evans blue staining, malondialdehyde estimation by Schiff reagent, lipid peroxidation, lignin deposition, and antioxidant enzyme activities assay. We observed that soil salinity reduced the phytotoxicity of aqueous extract and decreased its potential. The presence of different bioactive compounds improved the natural herbicidal properties of B. nigra and it can be used in various medicinal and agricultural practices.

“…Application of exogenous 1 mM spd + 10 mM proline + P. capsici was determined as the most effective application on 7 th day in two pepper cultivars. Similarly, in the study conducted by Chunthaburee et al (2015) they have detected that pre-treatment with spermidine increased phenolic content and antioxidant capacities in rice cultivars in salt stress. Exogenous spermidine may have stimulated the metabolic pathways leading to synthesis of certain groups of phenolic compounds.…”

Phytophthora blight (Phytophthora capsici Leon.), which is one of the most important disease factors incurring great economic losses, causes root crown rot. When pepper seedlings were pretreated with 0.1 mM spermidine (spd), 1 mM spd, 0.1 mM spd + 1 mM proline, 0.1 mM spd + 10 mM proline, 1 mM spd + 1 mM proline and 1 mM spd + 10 mM proline and then exposed to P. capsici, they improved their tolerance to subsequent P. capsici-induced oxidative damage. It was detected that cultivar 'Sirena RZ F1' was resistant to P. capsici and it was determined that cultivar 'Sera Demre-8' exhibited sensitive reaction. P. capsici stress caused an increase in total phenolic, malondialdehyde (MDA) and hydrogen peroxide (H 2 O 2 ) levels, as well as peroxidase (POX) and polyphenol oxidase (PPO) activities in leaves of pepper seedlings. Application of exogenous spermidine and spermidine + proline further increased PPO and POX activity, total phenolic amount. On the other hand, these applications in two cultivars and all days decreased the disease severity, necrosis length and MDA and H 2 O 2 amounts. These data show that antioxidants, especially polyphenol oxidase, peroxidase and total phenolic appear to protect pepper seedlings against stress-related damage. Moreover, spermidine and spermidine + proline have the potential to scavenge directly free radicals and promote the activity of antioxidant enzymes in pepper seedlings under P. capsici stress. In addition, it was also identified that especially 0.1 mM spd, 1 mM spd and 0.1 mM spd + 1 mM proline applications decreased the colony growth of P. capsici and the amount of zoospores. Therefore, we suggest that spermidine and spermidine + proline could play a protective role in protecting the pepper seedlings from P. capsici stress.
