“…Moreover, the retardant impact of water and salt stress on brassica napus plants were mitigated with SA application, with partial recovery in shoot and leaf growth and also boosting the photosynthesis synthesis rate and chlorophyll content leaves ( Saudy et al., 2023b ; Shaaban et al., 2023 ). Similar findings were also reported in various other crop species, including sweet basil ( Damalas, 2019 ), maize ( Bijanzadeh et al., 2019 ), sesame ( Najafabadi and Ehsanzadeh, 2017 ), sunflower ( Kosar et al., 2018 ), and squash ( El-Mageed et al., 2016 ). Our results supplements the idea that SA is playing apivotal role in defense mechanism and protecting the photosynthetic apparatus in brassica plants ( Kosar et al., 2018 ), with mitigating the photosynthetic and chlorophyll activities and thus encouraging overall plant growth traits in water deficit and saline stress conditions.…”

“…Another supplementary effect of SA could be attributed to stimulating the biosynthesis of protein kinases which plays a pivotal role in regulating cell division process at different stages of cell development ( Ali et al., 2013 ). Few other reports further describes that photosynthesis process and stomatal conductance elevates due to SA treatment under growing condition prone with various abiotic stresses ( Kosar et al., 2018 ). Similar kind of impact created by SA treatment was also recorded in Triticum aestivum L. ( Maghsoudi et al., 2019 ).…”

Under the changing climate due to global warming, various abiotic stresses including drought (D) and salinity (S) are expected to further trigger their devastating effects on the already vulnerable crop production systems. This experiment was designed to unravel and quantify the potential role of exogenous application of salicylic acid (SA) in mitigating both D and S stresses and their combination (D+S), with three replications using CRD (Completely Randomized Design). The obtained results of the current study demonstrated significant effects of all three types of stresses (D, S, and D+S) on various parameters in Brassica napus plants. Quantifying these parameters provides a more informative and precise understanding of the findings. Current results revealed that all three stress types (D, S, and D+S) resulted in a reduction in leaf area (13.65 to 21.87%), chlorophyll levels (30 to 50%), gaseous exchange rate (30 to 54%) and the concentration of mineral ions compared to non-stressed plants. However, application of SA helped in mitigating these stresses by ameliorating the negative effects of these stresses. Moreover, Malondialdehyde (MDA) contents, an indicator of lipid per-oxidation and oxidative stress, the levels of antioxidants, proline content, an osmolyte associated with stress tolerance, and sugar content in the leaves were elevated in response to all stress conditions. In addition, the ultra-structures within the leaves were negatively affected by the stresses, while an application of SA considerably minimized the deterioration of these structures thus providing protection to the brassica plants against the stresses. In a nutshell, the findings of this study suggest that SA application in S, D and S+ D stresses provides evasion to the plants by improving different physiological and growth indices. The application of Salicylic Acid (SA) mitigated the negative effects of the stresses on all the above parameters, reducing MDA contents (47%), antioxidants (11 to 20%), proline (28%), sugar contents (20.50%), and minimizing the deterioration of ultra-structures. The findings emphasize the potential mitigatory role of SA in mitigating D and S stresses and highlight the need for further research to understand the underlying mechanisms in detail and explore its practical application in farming practices.

“…As Mg is a necessary component for the production of chlorophyll concentrations, this could signi cantly impair chlorophyll biosynthesis (1,26). Nevertheless, Tre supplementing markedly boosted the production of chlorophyll content, suggesting that Trehalose supply may maintain membrane structure and the chlorophyll contents from osmotic damage by decreasing the activity of enzymes that break down chlorophyll during stress (50).…”

Heavy metal pollution poses a significant environmental challenge, adversely impacting global crop yields and posing health risks to humans. Cadmium (Cd), a non-essential and highly phytotoxic metal, poses substantial harm to overall plant metabolism even at minimal concentrations. The current research aimed to evaluate the beneficial impacts regarding priming of seeds of trehalose upon the development of cells able to photosynthesis traits, biochemical, and physiological and antioxidant defense systems among two variety of maize (FH-1046 and FH-5724) under Cd stress. For this purpose, a pot experiment was carried out in the University of Education Lahore, Faisalabad campus. After two weeks, growth parameters, biochemical and Cd concentration were examined. Results revealed that Cd significantly reduced the growth and maize variety FH5427 showed better growth as compared with FH1046. Chlorophyll contents also decreased under Cd stress and trehalose improved the photosynthetic efficiency under Cd stress. Carbohydrates and protein contents also reduced under Cd stress and trehalose significantly ameliorated the Cd stress in both maize varieties. Enzymatic and non-enzymatic antioxidants were greater under Cd stress and lower in trehalose treated group. This clearly showed the Cd alleviation potential of trehalose in maize plants. Trehalose also inhibits the movement of Cd into shoot from root system. Results also showed that Cd stress significantly decreased the growth, photosynthetic efficiency, and biochemical characteristics of two maize cultivars. However, the seeds treated with trehalose solution significantly reduce the impact of Cd stress. Moreover, it also enhances photosynthetic activity, enzymatic activities in requisites of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) and decreases the reactive oxygen species. The study suggests that priming maize seeds with trehalose could be effectively utilized in agricultural settings to enhance plant tolerance to cadmium stress.

“…The salinity problem is solved by removing salts out of the soil through excessive irrigation [5]. To counteract their harmful effects, plants have formed antioxidant enzymatic systems including ascorbate peroxidase (APX), superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), peroxidase (POD) and nonenzymatic scavengers like phenolic compounds, sulfur tripeptide (glutathione), vitamin C (L-ascorbic acid), vitamin E and carotenoids [6]. The enzymatic and non enzymatic antioxidants aimed to scavenge the reactive oxygen species such as Hydrogen peroxide, H 2 O 2 , superoxide radicals, O 2 , and hydroxyl radicals (OH.…”

Salinity stress, an ever-present challenge in agriculture and environmental sciences, poses a formidable hurdle for plant growth and productivity in saline-prone regions worldwide. Therefore, this study aimed to explore the effectiveness of trehalose and mannitol induce salt resistance in wheat seedlings. Wheat grains of the commercial variety Sakha 94 were divided into three groups : a group that was pre-soaked in 10 mM trehalose, another group was soaked in 10 mM mannitol, and the last was soaked in distilled water for 1 hour, then the pre soaked grains cultivated in sandy soil, each treatment was divided into two groups, one of which was irrigated with 150 mM NaCl and the other was irrigated with tap water. The results showed that phenols content in wheat seedlings increased and flavonoids reduced due to salt stress. Trehalose and mannitol cause slight increase in total phenols content while total flavonoids were elevated highy in salt-stressed seedlings. Furthermore, Trehalose or mannitol reduced salt-induced lipid peroxidation. Salt stress increases antioxidant enzyme activities of guaiacol peroxidase (G-POX), ascorbate peroxidase (APX), and catalase (CAT) in wheat seedlings, while polyphenol oxidase (PPO) unchanged. Trehalose and mannitol treatments caused an increase in APX, and CAT activities, whereas G-POX not altered but PPO activity were decreased under salt stress conditions. Molecular docking confirmed the interaction of Trehalose or mannitol with peroxidase and ascorbic peroxidase enzymes. Phenyl alanine ammonia layase (PAL) activity was increased in salt-stressed seedlings. We can conclude that pre-soaking of wheat grains in 10 mM trehalose or mannitol improves salinity stress tolerance by enhancing antioxidant defense enzyme and/or phenol biosynthesis, with docking identifying interactions with G-POX, CAT, APX, and PPO.
