“…As far as we know, this is the first time that the variability of fatty acid composition between populations of P. pinaster , P. halepensis and P. brutia is described. Some recent studies have shown that the chemical composition of seeds reflects the climatic conditions to which the plant was subjected, leading to differences between populations of pine species [39–41] . Our results agree with those studies because significant correlations were observed between the content of some fatty acids and certain ecologic parameters of P. halepensis populations.…”

The lipid fraction of seeds from different pine species and populations was studied regarding total lipid content, fatty acid profile and vitamin E composition. The investigated seeds contained a high percentage of lipid (13.6 to 31.5 %). Lipid fractions were found to be rich in vitamin E, which varied significantly among species and populations. P. halepensis (Ph−Hn) showed the highest content of vitamin E (256.3 mg/kg of seeds) and the uppermost content of α‐tocopherol (44 mg/kg). However, P. halepensis (Ph−Kas) was the richest in γ‐tocopherol (204.9 mg/kg). Lipid fractions had a low content of δ‐tocopherol (1.2 to 3.6 mg/kg. The highest content of γ‐tocotrienol (∼18 %) was determined for P. halepensis (Ph−Dc and Ph−Hn). Thirteen fatty acids were identified by GC‐FID with significant variation between the investigated species. The linoleic acid was the major fatty acid followed by oleic acid and palmitic acid. The chemical differentiation among species for the composition of fatty acids and vitamin E was confirmed by PCA. Significant correlations were observed between the content of vitamin E and fatty acids and ecological parameters of P. halepensis populations.

“…The lipids of seeds of four ephedra species (E. nevadensis, E. viridis, E. przewalskii, and E. gerardiana) contain delta5-unsaturated polymethylene-interrupted fatty acids (∆5-UPIFA): ∆5,9and ∆5,11-C18:2; ∆5,9,12-C18:3; ∆5,9,12,15-C18:4; ∆5,11-C20:2; ∆5,11,14-C20:3; and ∆5,11,14,17-C20:4 acids [20]. Our studies revealed that ∆5-UPIFA was detected in frost-tolerant coniferous [21] and in the aboveground parts of wintergreen species of horsetail [22].…”

The Composition and the Content of ∆-5 Sterols, Fatty Acids, and the Activity of Acyl-Lipid Desaturases in the Shoots of Ephedra monosperma, Introduced in the Botanical Garden of the Cryolithozone of Yakutia

Evergreen plants in permafrost ecosystems survive unfavorable autumn cooling and extremely low winter temperatures by maintaining optimal physiological activity of tissue cell membranes. To some extent, these features are due to the properties of shoot lipids performing a number of functions during adaptation. Sterols (STs) play a key role in regulating the fluidity and permeability of plant membranes (phytosterols) with a wide structural diversity. The composition of neutral lipids, STs, and fatty acids (FAs) in shoots of the evergreen shrub Ephedra monosperma growing in the Botanical Garden cryolithozone was first studied with HPTLC-UV/Vis/FLD and GC-MS. Twenty FAs were found, from C14:0 to C23:0; they included mono-, di-, tri-, and tetraene FAs. The high content of β-sitosterol among other ∆-5 sterols and an increased amount of C18:2(∆9,12) linoleic acid in lipids composition during the autumn–winter period was found to play an important role in the adaptation of ephedra shoots to the autumn–winter period, providing the cell membrane with greater plasticity, fluidity, and flexibility. The important role of diene linoleic fatty acid C18:2(∆9,12) in ephedra shoot lipids in the processes of low-temperature adaptation was shown.

“…While hysteresis is often invoked as a framework to think about antecedent hydrologic conditions (e.g., Sanderman et al., 2009; Wagner et al., 2019), we need a complementary framework to consider how plant growth stage impacts what biochemicals enter the DOM pool through leaching, and how fresh litter quantity and quality impact DOM chemistry. For example, low temperatures can increase conifer lipid content of needle cells (Nokhsorov et al., 2019; Pukacki & Kaminska‐Rozek, 2013), and season can impact tree DOM aromaticity, suggesting export of different compounds at different moments (Levia et al., 2012). The biochemicals being leached from trees at any given moment will depend on plant production/senescence, and the transit time of tree DOM to streams depends on flow path and retention time of tree DOM in soils.…”
