“…and Halocharis hispida (Schrenk) Bunge, with 22-29% GLs and 16-17% PLs in their extract 60 . In terms of the amounts of GLs and PLs per unit of leaves, a previous study reported values for several halophyte species to range between 5-47 mg GLs g −1 DW and 2-17 mg PLs g −1 DW 61 . Concerning the present study, H. portulacoides from the high-input treatments displayed values very similar to the upper-end of those ranges.…”

Halophytes are increasingly regarded as suitable extractive species and co-products for coastal Integrated Multi-Trophic Aquaculture (IMTA) and studying their lipidome is a valid means towards their economic valorization. Halimione portulacoides (L.) Aellen edible leaves are rich in functional lipids with nutraceutical and pharmaceutical relevance and the present study aimed to investigate the extent to which its lipidome remains unchanged under a range of dissolved inorganic nitrogen (N) and phosphorus (P) concentrations typical of aquaculture effluents. Lipidomics analysis, done by hydrophilic interaction liquid chromatography coupled to high resolution mass spectrometry, identified 175 lipid species in the lipid extract of leaves: 140 phospholipids (PLs) and 35 glycolipids (GLs). Plants irrigated with a saline solution with 20-100 mg DIN-N L −1 and 3-15.5 mg DIP-P L −1 under a 1-week hydraulic retention time displayed a relatively stable lipidome. At lower concentrations (6 mg DIN-N L −1 and 0.8 mg DIP-P L −1), plants exhibited less PLs and GLs per unit of leaves dry weight and the GLs fraction of the lipidome changed significantly. This study reveals the importance of analyzing the lipidomic profile of halophytes under different nutritional regimens in order to establish nutrient-limitation thresholds and assure production conditions that deliver a final product with a consistent lipid profile.

“…The lipids were extracted three times by a chloroform-methanol mixture (1:2, v/v) with the simultaneous mechanical destruction of the tissues (Kates, 1972). The lipids were separated by thin-layer chromatography as described earlier (Rozentsvet et al, 2014).…”

Some species of mammals can reproduce in anticipation of future food abundance. During 2017-2018 we studied the reproduction of a common abundant species, the yellow-necked mouse Sylvaemus flavicollis, in oak communities to determine if the timing of reproduction has a predictive character during the autumn peak of reproduction. During the maturation of acorns the proportion of females in oestrus gradually decreased along with the share of males with reproductive activity. By the time the acorns were completely ripe and fell, the most of juveniles became independent, and a portion of the young females became sexually mature. In 2018, a high yield oak year, the sexual activity of the males was considerably higher than that in 2017, a moderate yield oak year, what can point on its role in the regulation of the intensity of reproduction. Thus, instead of any prediction, mating and pregnancy in a large proportion of the mice, began at the beginning of acorn ripening, due to females feeding on immature seeds, eliminating a delay between forage yield and rodent reproduction. A possible reason for this synchronization is the contents of triacylglycerols, the main constituents of body fat in animals, in the rodent diet. During the maturation of acorns, its proportion increases considerably, which can increase the survival rate of juveniles.

“…Halophytes, as well as macroalgae, have large amounts of GLs ( ca. 50% of total lipid content), MGDG and DGDG being greater contributors to this lipid class than SQDG (only 6%–18% of total GLs) [ 34 , 35 ]. Although their content varies with environmental conditions, it is possible to find higher levels of SQDG in several species, such as the halophyte Calystegia soldanella and several brown macroalgae, especially in high salinity environments.…”

“…Although their content varies with environmental conditions, it is possible to find higher levels of SQDG in several species, such as the halophyte Calystegia soldanella and several brown macroalgae, especially in high salinity environments. The DGDG/MGDG ratio increases in response to a higher saline environment in various plant groups [ 34 ]. Indeed, high DGDG/MGDG ratio and PUFAs are related to salt tolerance, as changes in this ratio may affect the structure and microviscosity of membranes and condition the resistance of organisms to environmental stress [ 36 ].…”

Bioprospecting of Marine Macrophytes Using MS-Based Lipidomics as a New Approach

The marine environment supports a remarkable diversity of organisms which are a potential source of natural products with biological activities. These organisms include a wide variety of marine plants (from micro- to macrophytes), which have been used in the food and pharmaceutical industry. However, the biochemistry and biological activities of many of these macrophytes (namely macroalgae and halophytes, including seagrasses) are still far from being fully explored. Most popular bioactive components include polysaccharides, peptides, phenolics and fatty acids (FAs). Polar lipids (glycolipids, phospholipids and betaine lipids) are emerging as novel value-added bioactive phytochemicals, rich in n-3 FA, with high nutritional value and health beneficial effects for the prevention of chronic diseases. Polar lipids account various combinations of polar groups, fatty acyl chains and backbone structures. The polar lipidome of macrophytes is remarkably diverse, and its screening represents a significant analytical challenge. Modern research platforms, particularly mass spectrometry (MS)-based lipidomic approaches, have been recently used to address this challenge and are here reviewed. The application of lipidomics to address lipid composition of marine macrophytes will contribute to the stimulation of further research on this group and foster the exploration of novel applications.
