“…The CLs interact with other soluble mitochondrial proteins to stabilize the respiratory chain complexes and thus supports the structure of mitochondrial membrane under salt stress (Mårtensson et al 2017, Yu et al 2020). In vacuolar membrane of beetroot plant cell, the total content of phospholipids and glycoglycerolipids (MGDG, DGDG) reduced, whereas the level of saturated fatty acids elevated, which reduces the permeability of Na + and Cl − under salinity (Ozolina et al 2020).…”

“…The lipid dynamics of mitochondrial membranes was assessed in several plants, including Arabidopsis, barley, spinach, tobacco and mung bean using LC–MS (Zhou et al 2016). The gas chromatography–MS was used by Ozolina et al (2020) to analyze the sterols and fatty acids of the vacuolar membrane in beetroot under different osmotic stress. Matrix‐assisted laser desorption/ionization‐MS imaging used to show the differential distribution of lipids in different root zones of barley under salinity (Sarabia et al 2018).…”

The plasma membrane (PM) is possibly the most diverse biological membrane of plant cells; it separates and guards the cell against its external environment. It has an extremely complex structure comprising a mosaic of lipids and proteins. The PM lipids are responsible for maintaining fluidity, permeability and integrity of the membrane and also influence the functioning of membrane proteins. However, the PM is the primary target of environmental stress, which affects its composition, conformation and properties, thereby disturbing the cellular homeostasis. Maintenance of integrity and fluidity of the PM is a prerequisite for ensuring the survival of plants during adverse environmental conditions. The ability of plants to remodel membrane lipid and protein composition plays a crucial role in adaptation towards varying abiotic environmental cues, including high or low temperature, drought, salinity and heavy metals stress. The dynamic changes in lipid composition affect the functioning of membrane transporters and ultimately regulate the physical properties of the membrane. Plant membrane‐transport systems play a significant role in stress adaptation by cooperating with the membrane lipidome to maintain the membrane integrity under stressful conditions. The present review provides a holistic view of stress responses and adaptations in plants, especially the changes in the lipidome and proteome of PM under individual or combined abiotic stresses, which cause alterations in the activity of membrane transporters and modifies the fluidity of the PM. The tools to study the varying lipidome and proteome of the PM are also discussed.

“…Cell membranes are important sites perceiving abiotic stress signals, and, therefore, the recomposition of endogenous sterols in these structures improves plant stress resistance. A specific role in this process is played by C24-alkyl sterols, which enhance plant resistance to stress factors by improving the cohesion of cell membranes and changing the permeability of membranes, thereby affecting proton efflux [ 12 , 13 ]. The proportions between sitosterol and stigmasterol (which contains 22(23)-double bond in the side chain) and the ratios of certain conjugated sterol forms (i.e., sterol esters and sterol glycosides) can change under abiotic stress [ 11 ].…”

The present study investigated the changes in the content of steroids and triterpenoids in C. officinalis hairy root cultures and plants exposed to cadmium stress. The observed effects included the content and composition of analyzed groups of compounds, particularly the proportions among individual sterols (e.g., stigmasterol-to-sitosterol ratio), their ester and glycoside conjugates. The total sterol content increased in roots (by 30%) and hairy root culture (by 44%), whereas it decreased in shoots (by 15%); moreover, these effects were inversely correlated with Cd-induced growth suppression. Metabolic alterations of sterols and their forms seemed to play a greater role in the response to Cd stress in roots than in shoots. The symptoms of the competition between general metabolites (sterols) and specialized metabolites (triterpenoids) were also observed, i.e., the increase of the sterol biosynthesis parallel to the decrease of the triterpenoid content in C. officinalis plant roots and hairy root culture, and the inverse phenomenon in shoots. The similarity of the metabolic modifications observed in the present study on C. officinalis plant roots and hairy roots confirmed the possibility of application of plant in vitro cultures in initial studies for physiological research on plant response to environmental stresses.

“…As essential components of the cell membrane, plant sterols are regarded as a requirement for plants in response to abiotic stress [6]. Previous studies have shown that stress can lead to changes in plant sterols content [7,77]. It is worth noting that plant sterols can also improve plant stress resistance mainly through exogenous sterol treatment or changes in endogenous sterol content.…”

Plant sterols are important components of the cell membrane and lipid rafts, which play a crucial role in various physiological and biochemical processes during development and stress resistance in plants. In recent years, many studies in higher plants have been reported in the biosynthesis pathway of plant sterols, whereas the knowledge about the regulation and accumulation of sterols is not well understood. In this review, we summarize and discuss the recent findings in the field of plant sterols, including their biosynthesis, regulation, functions, as well as the mechanism involved in abiotic stress responses. These studies provide better knowledge on the synthesis and regulation of sterols, and the review also aimed to provide new insights for the global role of sterols, which is liable to benefit future research on the development and abiotic stress tolerance in plant.
