“…However, the link between lipid functions and the ER stress response is still poorly understood in plants. Yu et al (2018) verified that Arabidopsis glycerolipid homeostasis might be sustained at the post-transcriptional level under ER stress. Additionally, a study on maize illustrated that ER stress could affect the enzyme activity of diacylglycerol kinase (DGA), choline phosphate cytidylyltransferase, phosphatidylinositol-4-kinase, and PIPK ( Shank et al, 2001 ).…”

“…If the UPR is overextended and ER homeostasis cannot be sustained, cells will initiate programmed death ( Deng et al, 2013 ). In addition to aberrant proteins, instability of phospholipid metabolism also leads to ER stress and activates the UPR ( Yu et al, 2018 ). Studies on yeast and mammalian cells revealed that an imbalanced PC to PE ratio is a crucial cause of ER stress ( Fu et al, 2011 ; Thibault et al, 2012 ; Gao et al, 2015 ).…”

An Overview of Biomembrane Functions in Plant Responses to High-Temperature Stress

Biological membranes are highly ordered structures consisting of mosaics of lipids and proteins. Elevated temperatures can directly and effectively change the properties of these membranes, including their fluidity and permeability, through a holistic effect that involves changes in the lipid composition and/or interactions between lipids and specific membrane proteins. Ultimately, high temperatures can alter microdomain remodeling and instantaneously relay ambient cues to downstream signaling pathways. Thus, dynamic membrane regulation not only helps cells perceive temperature changes but also participates in intracellular responses and determines a cell’s fate. Moreover, due to the specific distribution of extra- and endomembrane elements, the plasma membrane (PM) and membranous organelles are individually responsible for distinct developmental events during plant adaptation to heat stress. This review describes recent studies that focused on the roles of various components that can alter the physical state of the plasma and thylakoid membranes as well as the crucial signaling pathways initiated through the membrane system, encompassing both endomembranes and membranous organelles in the context of heat stress responses.

“…PC biosynthesis is regulated by SnRK1 through the phosphorylation and activity inhibition of CTP:phosphocholine cytidyl transferase 1 in Arabidopsis [173]. In addition to this, the transcriptional level of PC and PE biosynthesis genes are regulated under ER stress, while ER-localized choline/ethanolamine kinase 1 is required for ER stress tolerance in Arabidopsis [174,175]. These studies indicate that salt-regulated PC production may have some correlation with the cellular energy status and ER stress during salt stress.…”

High salinity threatens crop production by harming plants and interfering with their development. Plant cells respond to salt stress in various ways, all of which involve multiple components such as proteins, peptides, lipids, sugars, and phytohormones. Phospholipids, important components of bio-membranes, are small amphoteric molecular compounds. These have attracted significant attention in recent years due to the regulatory effect they have on cellular activity. Over the past few decades, genetic and biochemical analyses have partly revealed that phospholipids regulate salt stress response by participating in salt stress signal transduction. In this review, we summarize the generation and metabolism of phospholipid phosphatidic acid (PA), phosphoinositides (PIs), phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylglycerol (PG), as well as the regulatory role each phospholipid plays in the salt stress response. We also discuss the possible regulatory role based on how they act during other cellular activities.

“…Finally, to dispose of dysfunctional ER regions, an autophagy process can be engaged [ 215 ]. In A. thaliana , where UPR pathway has been extensively studied, all those strategies destined to relieve ER stress have been found conserved [ 200 , 216 , 217 , 218 , 219 , 220 , 221 ], with the notable exception of the UPR-contingent regulation of phospholipid synthesis that was barely addressed thus far [ 222 ].…”

“…Yet, a seminal study has reported that the maize floury endosperm-2 mutant, expressing a mutated ER-resident protein that remains attached to the membrane, exhibited a constitutive ER stress associated with TAG and phospholipid over-accumulation in seeds [ 238 ], indicative of a causal role for this proteo-toxic stress in lipid changes. More recently, Arabidopsis phospholipid biosynthesis genes were proven misregulated in response to transient ER stress, but these variations in expression were not accompanied by any compelling glycerolipid phenotype [ 222 ]. The authors concluded on an active transcriptional regulation to maintain glycerolipid levels under stressful conditions.…”

Throughout their life cycle, plants face a tremendous number of environmental and developmental stresses. To respond to these different constraints, they have developed a set of refined intracellular systems including autophagy. This pathway, highly conserved among eukaryotes, is induced by a wide range of biotic and abiotic stresses upon which it mediates the degradation and recycling of cytoplasmic material. Central to autophagy is the formation of highly specialized double membrane vesicles called autophagosomes which select, engulf, and traffic cargo to the lytic vacuole for degradation. The biogenesis of these structures requires a series of membrane remodeling events during which both the quantity and quality of lipids are critical to sustain autophagy activity. This review highlights our knowledge, and raises current questions, regarding the mechanism of autophagy, and its induction and regulation upon environmental stresses with a particular focus on the fundamental contribution of lipids. How autophagy regulates metabolism and the recycling of resources, including lipids, to promote plant acclimation and resistance to stresses is further discussed.
