“…However, CAT activity was not significantly different at 100 and 150 mM salt concentration, and the lowest CAT activity was observed in control treatments of both cultivars in the study. Similar to our results, Jabeen and Ahmad [26] reported that CAT activity increased with increasing salt concentration in safflower and sunflower compared to control, and Alasvandyari and Mahdavi [32] found that CAT activity increased in safflower under 50, 100 and 150 mM salt concantrations compared to control. Salt stress increases ROS in plants and triggers oxidative damage in membranes [33].…”

The present study was carried out using Dinçer and Olas safflower varieties at 5 different salt (NaCl) concentrations (0, 50, 100, 150, and 200 mM) for 14 days. The germination percentages of the cultivars under salt conditions as well as the activities of antioxidant enzymes (SOD, CAT, POD and APX) and biochemical changes (protein and MDA) in the seedlings were determined. The germination percentage decreased with increased salt concentrations, and the greatest decrease in germination percentage was observed at a 200 mM salt concentration by 34% in both cultivars. The activity of superoxide dismutase (SOD) increased at low salt concentrations, but decreased after 100 and 150 mM salt concentrations, respectively. Catalase (CAT) and ascorbate peroxidase (APX) activities, as well as malondialdehyde (MDA) and hydrogen peroxide (H2O2) contents, increased with increasing salt concentrations at Dinçer and Olas, but total soluble protein content decreased with increasing salt concentration. Peroxidase (POD) activity was not significantly affected by salt stress in safflower. Germination percentage showed negative correlations with CAT, MDA and H2O2 levels, and showed a positive correlation with soluble protein content under salt stress in safflower. The present results may be useful to identify mechanisms of salt tolerance involving antioxidant enzyme activities and biochemical changes in safflower seedlings.

“…Glycine betaine is a quaternary ammonium compound that accumulates abundantly in response to dehydration and salt stress in many plants [62,63]. Glycine betaine is synthesized in the chloroplast, where it accumulates to play a role in the osmotic adjustment of the thylakoid membrane, therefore maintaining photosynthetic efficiency [64]. In response to salinity stress, glycine betaine is synthesized in many plants to alleviate the adverse effects of salt stress to maintain the osmotic status of the cell.…”

Soil salinization is a severe abiotic stress that negatively affects plant growth and development, leading to physiological abnormalities and ultimately threatening global food security. The condition arises from excessive salt accumulation in the soil, primarily due to anthropogenic activities such as irrigation, improper land uses, and overfertilization. The presence of Na⁺, Cl−, and other related ions in the soil above normal levels can disrupt plant cellular functions and lead to alterations in essential metabolic processes such as seed germination and photosynthesis, causing severe damage to plant tissues and even plant death in the worst circumstances. To counteract the effects of salt stress, plants have developed various mechanisms, including modulating ion homeostasis, ion compartmentalization and export, and the biosynthesis of osmoprotectants. Recent advances in genomic and proteomic technologies have enabled the identification of genes and proteins involved in plant salt-tolerance mechanisms. This review provides a short overview of the impact of salinity stress on plants and the underlying mechanisms of salt-stress tolerance, particularly the functions of salt-stress-responsive genes associated with these mechanisms. This review aims at summarizing recent advances in our understanding of salt-stress tolerance mechanisms, providing the key background knowledge for improving crops’ salt tolerance, which could contribute to the yield and quality enhancement in major crops grown under saline conditions or in arid and semiarid regions of the world.

Tomato (Lycopersiconesculentum L.) is a long duration crop belongs to a family Solanaceae. In case of vegetables, tomato is a second major crop, cultivated wide range throughout the world. Although, tomato is moderate sensitive to salinity yet for salinity tolerance more attention is required. More than 30% cultivated land all over the world severely affected by the salinity. In this scenario, experiment was designed to investigate various morphological and physiological aspects of tomato under various salinity levels; different levels of exogenous glycine betaine applications. Study was conducted to reveal the salt tolerance in tomato genotypes. Experiment was performed under controlled condition in the growth chamber of the IHS, UAF. Different concentrations of sodium chloride salt (0, 1.5 and 3 dS m-1) was used for salinity levels. Medium size plastic pots were used for sowing of tomato and sand was used as growing medium. Hoagland solution was applied for nourishment of tomato seedlings. Salinity was applied on 3-4 leaf stage. Then examined the effect of glycine betaine (0, 5, 10 and 15mM) for salt tolerance on tomato cultivars. Data of various attributes was collected and analyzed statistically by appropriate statistical package. Results revealed that tomato growth was negatively affected by the salinity. Morphological attributes and physiological attributes reduced in response to salinity except electrolyte leakage which amplified in salt stress. Exogenous application of glycine betaine promotes the tolerance against the salinity in the tomato genotypes and enhance growth.
