“…For example, treatment with 250 mM sodium chloride of Aegiceras corniculatum (L.) Blanco (a shrub that grows in moist soil in estuaries and river banks, often on the coastal edge of the mangrove zone) more than doubled the polyphenol content compared to control plants [65]. A study of salinity on the accumulation of biologically active compounds in the Crithmum maritimum L. halophyte revealed a significant accumulation of chlorogenic acid in leaves with increased salinity [66]. In another experiment [67], in a study of the effect of increased salinity on the total content of phenols, phenolic acids, antioxidant activity, and other compounds in Brassica napus var oleifera seedlings, it was shown that moderate salinization (25-50 mM NaCl) caused the greatest relative increase in the concentration of phenols.…”

Halophyte plants are known for their resistance to harsh environmental conditions associated with excess salts in their habitats. Their resistance to salinization is due, among other things, to their high ability to detoxify free radicals, owing to the relatively high content of antioxidants. On the coast of the Baltic Sea and in the lagoons, there are several rare halophyte species included in the Red Book of the Kaliningrad Region (Russia) and the Baltic region, such as Spergularia marina (L.) Griseb. and Glaux maritima L. The aim of the research was to study the accumulation of certain groups of phenolic compounds in different parts of S. marina and G. maritima plants under conditions of weak and strong soil salinity, as well as to analyze the antioxidant, antibacterial, and fungicidal activity of extracts of the studied plant species. The present study showed an increase in total phenolic content in the roots and shoots of S. marina, and the shoots of G. maritima, in response to increased soil salinity. At the same time, the total content of flavonoids in all the studied parts of the two plant species remained unchanged. However, the content of individual flavonoids (hesperetin, epicatechin, apigenin derivative, luteolin derivative) in S. marina increased, for G. maritima there was a tendency to reduce the content of flavonoids in roots and shoots with an increase in soil salinity. There was an increase in the total content of hydroxycinnamic acids in the roots of Glaux maritima, as well as an increase in the content of protocatechuic acid in the roots and shoots of Spergularia marina. A positive relationship was established between the antioxidant activity of S. marina root extracts and the total content of phenolic compounds, as well as G. maritima shoots extracts and the total content of phenolic compounds. Extracts of S. marina showed no antibacterial activity against Escherichia coli and Bacillus subtilis, and weak fungicidal activity of stem extracts and inflorescences grown on soils, with high levels of salinities, was detected against Candida albicans. The extracts of roots and shoots from G. maritima showed weak antimicrobial and fungicidal activity.

“…Many studies have offered evidence that salt − induced membrane lipid alterations are curial to maintain membrane homeostasis in halophytes under salt stress (Guo et al 2022;Lin and Wu 1996). In fact, halophytic plants prone to increase their lipidic contents for enhanced salt tolerance (Castillo et al 2022). The tolerance accession of P. vaginatum showed greatly increased accumulation of lipids after salt treatment compared to the sensitive ones (Fig.…”

“…The increase was particularly noticeable in the galactolipids DGDGs, resulting in the tolerant accession to decrease their MGDG/DGDG ratio compared to the sensitive accession. Both the overall increase in lipids and the particular decrease in MGDG/DGDG ratio have been linked to the maintenance of membrane uidity and permeability during osmotic stress (Castillo et al 2022).…”

Background and aims Soil salinization is a growing problem for agriculture worldwide. To elucidate the mechanism underlying the salt tolerance of halophytes can offer a new angle for developing salt−tolerant crops. Seashore paspalum (Paspalum vaginatum Sw.) is a halophytic turfgrass and genomic model system for salt tolerance research in cereals and other grasses. However, knowledge regarding the tolerance mechanism of this halophyte remains largely unknown. Methods The two P.vaginatum accessions with contrasting salinity tolerance were employed to investigate the relationship between Na+ accumulation, lipid metabolism, antioxidant response and tissue−dependent salt tolerance using ICP−MS−based ion analysis, lipidomic profiling analysis, enzyme assay and integrated transcriptomic and metabolomic analysis, respectively. Gene−metabolite network analysis was carried to identify the significant TF genes and metabolites associated with salt tolerance in P.vaginatum plants. Results We found that salt−tolerant P.vaginatum built up tissue−specific strategies accompanied with Na+ accumulation in response to salt stress. Antioxidant system and amino acid metabolism were curial to maintain high salinity tolerance in leaves of P. vaginatum plants. On the contrary, lipid upregulation is the important components of the salt−tolerant mechanism in roots of P. vaginatum. Furthermore, 109 TF genes were identified to be linked to salt tolerance, conferring to salinity tolerance in this halophytic grass. Conclusions Our results expand our understanding of the underlying salt tolerance of seashore halophyte grass for the breeding and genetic engineering of salt tolerance in crop plants.

“…Besides, the interaction of salinity with nutrient limitation induces higher unsaturated fatty acids than saturated fatty acids. An increase in unsaturated to saturated fatty acid ratio is a crucial response against salinity stress as unsaturation increases plasma membrane permeability and fluidity (Castillo et al, 2022). Similarly, the proline, flavonoid, glycine betaine, anthocyanin, ascorbic acid content, and catalaseperoxidase activity increased at the expense of chlorophyll, biomass, and protein content up on exposure to Seidlitzia rosmarinus (desert halophyte) against salinity (0, 300, and 600 mm NaCl) and mineral dust (0 and 1.5 g/m 2 month; Zilaie et al, 2022).…”

Anthropogenic activities have a critical influence on climate change that directly or indirectly impacts plant and microbial diversity on our planet. Due to climate change, there is an increase in the intensity and frequency of extreme environmental events such as temperature rise, drought, and precipitation. The increase in greenhouse gas emissions such as CO2, CH4, NOx, water vapor, increase in global temperature, and change in rainfall patterns have impacted soil–plant-microbe interactions, which poses a serious threat to food security. Microbes in the soil play an essential role in plants’ resilience to abiotic and biotic stressors. The soil microbial communities are sensitive and responsive to these stressors. Therefore, a systemic approach to climate adaptation will be needed which acknowledges the multidimensional nature of plant-microbe-environment interactions. In the last two scores of years, there has been an enhancement in the understanding of plant’s response to microbes at physiological, biochemical, and molecular levels due to the availability of techniques and tools. This review highlights some of the critical factors influencing plant-microbe interactions under stress. The association and response of microbe and plants as a result of several stresses such as temperature, salinity, metal toxicity, and greenhouse gases are also depicted. New tools to study the molecular complexity of these interactions, such as genomic and sequencing approaches, which provide researchers greater accuracy, reproducibility, and flexibility for exploring plant-microbe–environment interactions under a changing climate, are also discussed in the review, which will be helpful in the development of resistant crops/plants in present and future.
