“…24 Moreover SA application has also been reported to control stomatal opening under stress, leading to a decrease in transpiration and water loss, as well as the maintenance of turgor, and controlling the growth and productivity of plants under stress conditions. 25,54 Furthermore, wheat seedlings treated with exogenous Toc showed better growth parameters than those treated without the substance. Previous studies reported that TP can improve tolerance of plants subjected to stress conditions including salinity, which corroborates our findings.…”

“…Salicylic acid (SA) is a phenolic molecule that regulates plant growth and development both in optimal and stressful conditions. − Plants have been found to be protected from abiotic stresses by salicylic acid since it regulates a variety of physiological processes, including photosynthesis, proline metabolism, N metabolism, glycine betaine biosynthesis, antioxidant mechanism, and plant-water status. Therefore, SA has been implicated in plants’ resistance to various abiotic stresses, including ozone, metals, UV-B radiation, extreme temperatures, droughts, and salinity …”

Background: Soil salinity negatively impacts agricultural productivity. Consequently, strategies should be developed to inculcate a salinity tolerance in crops for sustainable food production. Growth regulators play a vital role in regulating salinity stress tolerance. Methods: Thus, we examined the effect of exogenous salicylic acid (SA) and alpha-tocopherol (TP) (100 mg/L) on the morphophysio-biochemical responses of two wheat cultivars (Pirsabak-15 and Shankar) to salinity stress (0 and 40 mM). Results: Both Pirsabak-15 and Shankar cultivars were negatively affected by salinity stress. For instance, salinity reduced growth attributes (i.e., leaf fresh and dry weight, leaf moisture content, leaf area ratio, shoot and root dry weight, shoot and root length, as well as root−shoot ratio), pigments (chlorophyll a, chlorophyll a, and carotenoids) but increased hydrogen peroxide (H 2 O 2 ), malondialdehyde (MDA), and endogenous TP in both cultivars. Among the antioxidant enzymes, salinity enhanced the activity of peroxidase (POD) and polyphenol oxidase (PPO) in Pirsabak-15; glutathione reductase (GR) and PPO in Shankar, while ascorbate peroxidase (APOX) was present in both cultivars. SA and TP could improve the salinity tolerance by improving growth and photosynthetic pigments and reducing MDA and H 2 O 2 . In general, the exogenous application did not have a positive effect on antioxidant enzymes; however, it increased PPO in Pirsabak-15 and SOD in the Shankar cultivar. Conclusions: Consequently, we suggest that SA and TP could have enhanced the salinity tolerance of our selected wheat cultivars by modulating their physiological mechanisms in a manner that resulted in improved growth. Future molecular studies can contribute to a better understanding of the mechanisms by which SA and TP regulate the selected wheat cultivars underlying salinity tolerance mechanisms.

“…Salt stress has been found to negatively affect crop yields and productivity, among other environmental factors (Munns & Tester, 2008; Pasala et al, 2016). It induces osmotic stress and reduces water intake, leading to a decreased relative water content and water potential, resulting in growth retardation, stomatal closure, reduced transpiration, and reduced photosynthesis (Ahanger et al, 2018; Pirasteh‐Anosheh et al, 2022; Punia et al, 2021; Shams et al, 2019). It also affects DNA methylation and the expression of tolerance‐responsive genes.…”

The synthesis of capsaicinoids occurs in the placenta of the fruits of pungent peppers. However, the mechanism of capsaicinoids' biosynthesis in pungent peppers under salinity stress conditions is unknown. The Habanero and Maras genotypes, the hottest peppers in the world, were chosen as plant material for this study, and they were grown under normal and salinity (5 dS m−1) conditions. The results showed that salinity stress harmed plant growth but increased the capsaicin content by 35.11% and 37.00%, as well as the dihydrocapsaicin content by 30.82% and 72.89% in the fruits of the Maras and Habanero genotypes, respectively, at 30 days after planting. The expression analysis of key genes in capsaicinoids biosynthesis revealed that the PAL1, pAMT, KAS, and PUN1 genes were overexpressed in the vegetative and reproductive organs of pungent peppers under normal conditions. However, under salinity stress, overexpression of PAL1, pAMT, and PUN1 genes was identified in the roots of both genotypes, which was accompanied by an increase in capsaicin and dihydrocapsaicin content. The findings showed that salinity stress caused an enhancement in the capsaicin and dihydrocapsaicin contents in the roots, leaves, and fruits of pungent peppers. Nonetheless, it was found that the production of capsaicinoids is generally not restricted to the fruits of pungent peppers.
