“…The deleterious impacts of SS on multiple physiological systems, including photosynthesis, ion homeostasis, and antioxidant enzyme activity, have been reported in a wide array of crop plants. The increase in Na+ and Cl-ions in many plants has frequently been linked to the detrimental effects of salt; as a result, these ions provide essential circumstances for plant life by interfering with various plant processes (Pourebrahimi et al 2023). The current study showed that all measured growth attributes such as root-shoot length and their fresh as well as dry weight (Figure 1 a-f) were reduced under SS (NaCl was applied at the rate of 100 ppm).…”

Salt stress (SS) has emerged as one of the most pressing environmental threats to the production sustainability of oil-seed crops like camelina which necessitates finding out pro-environment and biologically feasible amelioration approaches. A study was performed to investigate the effects of exogenously applied silicon (Si) and selenium (Se) on two camelina varieties (Australian and Canadian) under SS conditions. The trial was comprised of two doses of Si and Se (5 and 10 ppm each) along with two co-application treatments entailing Si (5pp) + Se (5ppm) and Si (10 pp) + Se (10 ppm), whereas control treatments were kept for comparison purpose. The response variables included root-shoot length, fresh and dry weights, as well as leaf photosynthetic pigment content (chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids), leaf gas exchange attributes, biochemical characters (total proline, total soluble sugar, total soluble protein, and total free amino acid) and antioxidant activities (APX, POD, CAT, and SOD). Results showed that SS significantly reduced all growth attributes of camelina, whereas the Australian camelina variety demonstrated greater salinity tolerance in comparison to the Canadian variety. The co-application of Si (10 pp) + Se (10 ppm) outperformed the rest of the treatments by recording the highest leaf chlorophyll a (1.69 mg/g FW), chlorophyll b (1.02 mg/g FW), carotenoids (2.89 mg/g FW), photosynthetic rate (17.02 µmole CO2 m− 2 s− 1), transpiration rate (3.65 µmole CO2 m− 2 s− 1), stomatal conductance (0.38 µmole CO2 m− 2 s− 1), total proline (199.38 µmole/g DW), total soluble sugar (120.95 µmole/g FW), total soluble protein (12.02 mg/g DW) and total free amino acid (37.15 mg/g DW) in Australian camelina as compared to Canadian camelina. The same treatment also remained effective in triggering the activity of APX (3.89 Unit/min/g FW), CAT (165.19 Unit/min/g FW), POD (178.95 Unit/min/g FW), and SOD (237.63 Unit/min/g FW). Thus, the combined exogenous application of Si and Se holds bright perspectives in alleviating the deleterious impact of SS especially for the Australian variety, and could be recommended to camelina growers after thorough field investigations.

“…The cultivated strawberry (Fragaria × ananassa, 8x) holds economic significance due to its nutritional richness and distinctive flavor profile (Mao et al, 2023;Song et al, 2024). However, strawberries are highly sensitive to salt stress (Mohammad et al, 2023). Thus, it is important to enhance the strawberry tolerance of salt stress.…”

As climate change and human activities continue to influence the environment, the area of arable land has been decreasing and becoming more susceptible to the impact of salt ions. Consequently, understanding the molecular mechanisms behind hydrogen's mitigation of plant salt tolerance is essential. In this study, strawberries were selected as the test plants, and analyses including physiological, biochemical, transcriptomic, and metabolomic approaches were conducted to elucidate the effects of hydrogen-rich water (HRW) under salt stress. The results indicated that under 100 mM salt stress, HRW significantly promoted plant growth, particularly increasing root biomass by 49.50%. Additionally, HRW regulated the levels of soluble sugars, malondialdehyde (MDA), and antioxidant enzymes, enhancing the cellular uptake of potassium ions and the expulsion of sodium ions. The levels of Ca2+ and Mg2+ in organelles increased by 2.06 and 2.45-fold, respectively. Transcriptomic analysis revealed that HRW substantially altered gene expression in strawberry roots; under salt stress, HRW up-regulated beneficial biological processes. Furthermore, genes related to ion absorption and transport, antioxidant enzymes, and cell wall biosynthesis were screened. Through integrating transcriptomic and metabolomic analyses which identified key common pathways in the differentially expressed metabolites (DEMs) and differentially expressed genes (DEGs) related to phenylpropanoid biosynthesis, alanine, aspartate, and glutamate metabolism, amino sugar and nucleotide sugar metabolism, and galactose metabolism. A molecular mechanism for mitigating salt stress in strawberry seedlings by HRW was provided by the integrated approaches in this research, reflecting the potential applications of hydrogen gas in agriculture.

“…Wang et al [10] showed that a low concentration of sodium selenite promoted filamentous microalga growth by increasing chlorophyll content and antioxidant capacity. In a hydroponics experiment, Pourebrahimi et al [11] reported that sodium selenate strengthened the enzymatic and non-enzymatic antioxidant systems of strawberries, thereby reducing the malondialdehyde content, neutralizing the effect of salinity stress, and increasing the fruit yield and size. Further, it has been found that Se application can regulate the soil-plant rhizosphere microenvironment.…”

Soil selenium (Se) speciation characteristics and their influence on the Se enrichment pattern and physiological characteristics of oilseed rape are poorly understood. We investigated dynamic changes in rhizosphere soil physicochemical properties, Se uptake and partitioning, biomass, and physiological indices in oilseed rape under five exogenous Se condition levels (0, 1.0, 2.5, 5.0, and 10.0 mg kg−1 Se in sodium selenite) using soil cultivation experiments. The rhizosphere pH and dissolved organic carbon in the soil solution were higher than those of the non-rhizosphere soil solution. The total Se, water-soluble Se, exchangeable Se, and organic Se contents in soils, as well as rapeseed root/leaf Se contents, significantly increased with increasing exogenous Se. Under 2.5 mg kg−1 Se, the biomass of rapeseed roots and leaves increased at the sixth week (82% and 58%) and eighth week (48% and 32%), respectively, reaching the highest level. Applications of 5.0 mg kg−1 Se at 6 and 8 weeks significantly increased the glutathione peroxidase activity (49%/82%), and decreased malondialdehyde content (23%/39%). Canonical correlation and ridge regression analyses showed that Se in the rapeseed roots/leaves significantly and positively correlated with water-soluble Se, exchangeable Se, and organic Se in rhizosphere soil. Overall, moderate-concentration Se soil application benefited oilseed rape growth (optimum = 2.5 mg kg−1 Se). Our findings reveal the response of oilseed rape to soil Se application based on plant growth and physiological traits, rhizospheric soil solution properties, and Se speciation transformation.
