“…Phosphatidylcholine (PC) is one of the major structural components of cellular membranes and plays other critical roles in plant vegetative and reproductive developmental stages( Wang et al, 2006 ; Higashi and Saito, 2019 ; Nakamura, 2021 ; Yu et al, 2021 ). PC is required for cell proliferation and differentiation ( Nakamura, 2021 ; Yu et al, 2021 ). Based on the previous studies, the content of the major phospholipids PC was changed in different patterns in a variety of plant species, which were not very consistent, probably due to dynamic turnover of the PC lipids and differences in plant sources and growth conditions ( Nakamura, 2021 ; Yu et al, 2021 ).…”

“…Ten of the PG species were measured, and the heat-induced reduction was mainly resulted from the molecular species of PG, such as 17:0/20:1-PG, 29:4-PG, 40:5-PG, 16:0/16:0-PG, 16:0/18:1-PG, 40:7-PG, 44:9-PG, 43:6-PG, and 9:0/10:4-PG whereas the level of 16:1/18:3-PG increased under heat stress ( Figure 5D ). Accumulated data suggest that the largest proportion of lipid species contain 36 and 34 acyl carbons, indicating two 18-C fatty acid chains or a combination of 16-C and 18-C chains when lipidomic analysis was performed in a variety of plant species ( Devaiah et al, 2006 ; Okazaki and Saito, 2014 ; Higashi et al, 2015 ; Mueller et al, 2015 , 2017 ; Yu et al, 2021 ). In contrast, the lipid species with 38 acyl carbons or more, containing one chain of 20–26 carbons (very long-chain fatty acids, VLCFAs) plus one 18-C chain are generally less abundant ( Devaiah et al, 2006 ; Okazaki and Saito, 2014 ; Higashi et al, 2015 ; Mueller et al, 2015 , 2017 ; Yu et al, 2021 ).…”

As we found, the four decreasing species with VLCFAs are highly desaturated, such as 40:5-PG, 40:7-PG, 43:6-PG, and 44:9-PG, which may contain one chain of 20–26 carbons ( Figure 5D ).…”

Characterization of the alterations in leaf lipidome in Begonia (Begonia grandis Dry subsp. sinensis) under heat stress will aid in understanding the mechanisms of stress adaptation to high-temperature stress often occurring during hot seasons at southern areas in China. The comparative lipidomic analysis was performed using leaves taken from Begonia plants exposed to ambient temperature or heat stress. The amounts of total lipids and major lipid classes, including monoacylglycerol (MG), diacylglycerol (DG), triacylglycerols (TG), and ethanolamine-, choline-, serine-, inositol glycerophospholipids (PE, PC, PS, PI) and the variations in the content of lipid molecular species, were analyzed and identified by tandem high-resolution mass spectrometry. Upon exposure to heat stress, a substantial increase in three different types of TG, including 18:0/16:0/16:0, 16:0/16:0/18:1, and 18:3/18:3/18:3, was detected, which marked the first stage of adaptation processes. Notably, the reduced accumulation of some phospholipids, including PI, PC, and phosphatidylglycerol (PG) was accompanied by an increased accumulation of PS, PE, and phosphatidic acid (PA) under heat stress. In contrast to the significant increase in the abundance of TG, all of the detected lysophospholipids and sphingolipids were dramatically reduced in the Begonia leaves exposed to heat stress, suggesting that a very dynamic and specified lipid remodeling process is highly coordinated and synchronized in adaptation to heat stress in Begonia plants.

Interplay between membrane proteins and membrane protein‐lipid pertaining to plant salinity stress

High salinity in agricultural lands is one of the predominant issues limiting agricultural yields. Plants have developed several mechanisms to withstand salinity stress, but the mechanisms are not effective enough for most crops to prevent and persist the salinity stress. Plant salt tolerance pathways involve membrane proteins that have a crucial role in sensing and mitigating salinity stress. Due to a strategic location interfacing two distinct cellular environments, membrane proteins can be considered checkpoints to the salt tolerance pathways in plants. Related membrane proteins functions include ion homeostasis, osmosensing or ion sensing, signal transduction, redox homeostasis, and small molecule transport. Therefore, modulating plant membrane proteins' function, expression, and distribution can improve plant salt tolerance. This review discusses the membrane protein–protein and protein–lipid interactions related to plant salinity stress. It will also highlight the finding of membrane protein–lipid interactions from the context of recent structural evidence. Finally, the importance of membrane protein–protein and protein–lipid interaction is discussed, and a future perspective on studying the membrane protein–protein and protein–lipid interactions to develop strategies for improving salinity tolerance is proposed.
