“…Like A. halimus, C. album growth was not affected by salinity. This is in contrast with the results of Rasouli et al [68], who found that FW dropped already at 100 mM NaCl in C. album; conversely, it is in agreement with the findings of Ivanova et al [69], who did not record biomass variations up to 200 mM NaCl.…”

Owing to the high interspecific biodiversity, halophytes have been regarded as a tool for understanding salt tolerance mechanisms in plants in view of their adaptation to climate change. The present study addressed the physiological response to salinity of six halophyte species common in the Mediterranean area: Artemisia absinthium, Artemisia vulgaris, Atriplex halimus, Chenopodium album, Salsola komarovii, and Sanguisorba minor. A 161-day pot experiment was conducted, watering the plants with solutions at increasing NaCl concentration (control, 100, 200, 300 and 600 mM). Fresh weight (FW), leaf stomatal conductance (GS), relative water content (RWC) and water potential (WP) were measured. A principal component analysis (PCA) was used to describe the relationships involving the variables that accounted for data variance. A. halimus was shown to be the species most resilient to salinity, being able to maintain FW up to 300 mM, and RWC and WP up to 600 mM; it was followed by C. album. Compared to them, A. vulgaris and S. komarovii showed intermediate performances, achieving the highest FW (A. vulgaris) and GS (S. komarovii) under salinity. Lastly, S. minor and A. absinthium exhibited the most severe effects with a steep drop in GS and RWC. Lower WP values appeared to be associated with best halophyte performances under the highest salinity levels, i.e., 300 and 600 mM NaCl.

“…3c). In the study of Ivanova et al (2016), it was reported that C. album has the ability to maintain the concentration of Na + and Cl − in cell organs at a level similar to untreated plants by using them for osmoregulatory purposes, while concomitant ultrastructural changes in cell organelles were observed. According to these researchers, the contribution of Na + and Cl − to osmolarity in leaves increased with increasing NaCl concentrations in nutrient solution up to the highest concentration (more than 100 mmol/kg f.w.)…”

Background: Recent trends in the food science industry and consumers' preferences for diversified diets suggest the consumption of wild greens not only as diet complements but also as healthy and functional foods for targeted conditions, rendering its commercial cultivation of major importance in order to avoid irrational gathering and genetic erosion threats. The Mediterranean basin abounds in wild edible species which have been used for food and medicinal purposes by human throughout the centuries. Many of these species can be found near coastal areas and usually grow under saline conditions, while others can adapt in various harsh conditions including high salinity. Scope and approach: The aim of this review focuses on listing and describing the most important halophyte species that traditionally have been gathered by rural communities of the Mediterranean basin, while special interest will be given on their chemical composition and health promoting components. Cases of commercially cultivated halophytes will be also presented to highlight their potential as alternative cash crops, while results from in vitro and in vivo health effects will be presented. Key findings and conclusions: The recent literature has provided useful information regarding the potential of wild halophytes as promising ingredients in functional food products and/or as sources of bioactive compounds. However, further research is needed regarding the chemical characterization of these species under commercial cultivation practices, while further clinical and model trials have to be conducted to assess their long term bioactivity and elucidate potential toxic effects and regulations of safe consumption.

“…Lipids play a particularly significant role in adapting to low‐ and high‐temperature stress, maintaining the level of cell membrane fluidity, as mountain ecosystems are characterized by drastic temperature changes during the diurnal cycle. Specific features of lipid FA composition may contribute to plant tolerance to dehydration, salt stress, as well as biotic environmental factors . In mountain ecosystems, plants can be exposed to several stressors at the same time, and the level of this exposure is consistent with altitudinal zonation.…”

One of the mechanisms of plant adaptation to combined stress under conditions of altitudinal zonation is changing the lipid fatty acid (FA) composition. The main changes in the FA composition occurred in the outer cell layers of the pericarp, but not in the parenchyma. Adaptation was found to be species-specific. In Cydonia oblonga MILL. and Malus domestica BORKH., the ratio of polyunsaturated 18:2 and 18:3 lipid FAs changed with increasing height, while a constitutive level of the unsaturation index (UI) and low contents of very-long-chain fatty acids (VLCFAs) were maintained. Mespilus germanica L. was characterized by a higher level of VLCFAs due to the high content of 20:0. The sum of VLCFAs in medlar increased by up to 16 % with changing altitude, which was accompanied by the changes in the ultrastructure of chloroplasts and a noticeable decrease in the UI. We attribute the differences in the adaptive strategies in C. oblonga, M. domestica and M. germanica to specific structural features of the pericarp peel. Despite different adaptation mechanisms, the studied species can grow equally successfully at the altitudes from 300 to 1200 m. Figure 4.
