“…Similar results have been described in Arabidopsis and Thellungiella salsuginea leaves during cold acclimation (Moellering et al , Degenkolbe et al , Zhang et al ). Low temperature produced a reduction in MGDG and a concomitant increase in DGDG content, as well as the appearance of tri and tetragalactolipids (not detected in this work; Moellering et al , Degenkolbe et al , Zhang et al ). As MGDG is a non‐bilayer lipid that can severely destabilize membranes, whereas DGDG is a bilayer lipid that may increase membrane stability, it is proposed that an increase in the ratio of bilayer‐ to non‐bilayer‐forming membrane lipids results in the stabilization of membranes during freezing (Hincha et al ).…”

“…On the contrary, the total MGDG content decreased in SL, FD, EL, RG and LM varieties after cold treatment (especially in CS21 vs H), meanwhile the relative amount of some specific species of MGDG (MGDG 36:4,in CS vs RS;MGDG 36:5 in CS21 vs H and in CS vs RS) decreased in all the six varieties (Tables S6 and S10). Similar results have been described in Arabidopsis and Thellungiella salsuginea leaves during cold acclimation (Moellering et al 2010, Degenkolbe et al 2012, Zhang et al 2013.

Peaches ripen and deteriorate rapidly at room temperature. Therefore, refrigeration is used to slow these processes and to extend fruit market life; however, many fruits develop chilling injury (CI) during storage at low temperature. Given that cell membranes are likely sites of the primary effects of chilling, the lipidome of six peach varieties with different susceptibility to CI was analyzed under different postharvest conditions. By using liquid chromatography coupled to mass spectrometry (LC-MS), 59 lipid species were detected, including diacyl- and triacylglycerides. The decreases in fruit firmness during postharvest ripening were accompanied by changes in the relative amount of several plastidic glycerolipid and triacylglyceride species, which may indicate their use as fuels prior to fruit senescence. In addition, levels of galactolipids were also modified in fruits stored at 0°C for short and long periods, reflecting the stabilization of plastidic membranes at low temperature. When comparing susceptible and resistant varieties, the relative abundance of certain species of the lipid classes phosphatidylethanolamine, phosphatidylcholine and digalactosyldiacylglycerol correlated with the tolerance to CI, reflecting the importance of the plasma membrane in the development of CI symptoms and allowing the identification of possible lipid markers for chilling resistance. Finally, transcriptional analysis of genes involved in galactolipid metabolism revealed candidate genes responsible for the observed changes after cold exposure. When taken together, our results highlight the importance of plastids in the postharvest physiology of fruits and provide evidence that lipid composition and metabolism have a profound influence on the cold response.

“…The amounts of lysophospholipid species, lysoPC and lysoPE, and PA increased when Arabidopsis plants were cold acclimated at 4 °C or exposed to freezing stress (Welti et al ). PA levels also increased in cold‐tolerant Eutrema salsugineum plants upon chilling (10‐fold) and freezing (100‐fold) (Zhang et al ). Both, the PLD and PLC/DGK pathways, are involved in the chilling‐induced and freezing‐induced PA formation, but the molecular species of PA differ and activate different targets (Ruelland et al ; Arisz et al ; Li et al ).…”

Lipids are one of the major components of biological membranes including the plasma membrane, which is the interface between the cell and the environment. It has become clear that membrane lipids also serve as substrates for the generation of numerous signalling lipids such as phosphatidic acid, phosphoinositides, sphingolipids, lysophospholipids, oxylipins, N-acylethanolamines, free fatty acids and others. The enzymatic production and metabolism of these signalling molecules are tightly regulated and can rapidly be activated upon abiotic stress signals. Abiotic stress like water deficit and temperature stress triggers lipid-dependent signalling cascades, which control the expression of gene clusters and activate plant adaptation processes. Signalling lipids are able to recruit protein targets transiently to the membrane and thus affect conformation and activity of intracellular proteins and metabolites. In plants, knowledge is still scarce of lipid signalling targets and their physiological consequences. This review focuses on the generation of signalling lipids and their involvement in response to abiotic stress. We describe lipid-binding proteins in the context of changing environmental conditions and compare different approaches to determine lipid-protein interactions, crucial for deciphering the signalling cascades.

“…Given the importance of storage lipid catalysis, the PA pool could have critical functions during germination. Under conditions of dehydration and low temperature, PA is derived mainly from phospholipase D-mediated hydrolysis of phospholipids (Zhang, Wang, Zhang, Tao & Li, 2013). However, it is largely unknown whether and how the composition of membrane lipids changes and functionally contributes to germination.…”

Imbibitional chilling injury during germination causes agricultural losses but this can be overcome by osmopriming. It remains unknown how membranes reorganize during germination. Herein, we comparatively profiled changes of membrane lipids during imbibition under normal and chilling temperatures in chilling-tolerant and -sensitive soybean seeds. We found three patterns of dynamic lipid remodelling during the three phases of germination. Pattern 1 involved a gradual increase in plastidic lipids during phases I and II, with an abrupt increase during phase III. This abrupt increase was associated with initiation of photosynthesis. Pattern 3 involved phosphatidic acid (PA) first decreasing, then increasing, and finally decreasing to a low level. Pattern 1 and 3 were interrupted in chilling-sensitive seeds under low temperature, which lead a block in plastid biogenesis and accumulation of harmful PA respectively. However, they were rescued and returned to their status under a normal temperature after polyethylene glycol (PEG) osmopriming. We specifically inhibited phospholipase D (PLD)-mediated PA formation in chilling-sensitive seeds of soybean, cucumber, and pea and found their germination under low temperature was significantly improved. These results indicate that membranes undergo specific and functional reorganization of lipid composition during germination and demonstrate that PLD-mediated PA causes imibibitional chilling injury.
