Total thylakoid protein synthesis, however, lagged behind galactolipid synthesis, suggesting that proteins are inserted secondarily into the galactolipid matrix of the thylakoid membrane during development. In addition to phospholipids, plant cell membranes contain other types of lipids, such as the phosphorus-free galactolipids. Different organ or organelle membranes are characterized by a distinct composition of membrane lipids, which affects both structure (e.g., membrane rigidity) and function (e.g., ion channels; Harayama and Riezman, 2018). Galactolipids, monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG), are the predominant lipid classes in the thylakoid membrane of chloroplasts. These lipids are also major constituents of internal membrane structures called prolamellar bodies (PLBs) and prothylakoids (PTs) in etioplasts, which develop in the cotyledon cells of dark-grown angiosperms. 2014-9-16 Sulfolipids Glycerophospholipids are made up of a 1,2-diacylglycerol and a polar head group alcohol attached by a phosphodiester bond Galactolipids Sulfolipids are common in plant membranes Sulfolipids contain sulfate Glycerophospholipids have hydrocarbons linked to glycerol by bonds that are more stable in acidic or high temperature environments. 2017-12-4 · membranes.

PubMed CrossRef Google Scholar 2019-07-01 · Triacylglycerol (TAG) is mainly synthesized in the ER and also chloroplastic envelop membranes (Fig. 1 B). TAG accumulates within the membrane bilayer and subsequently forms lipid droplets in the cytosol [,, ]. Establishment of the progenitor of chloroplasts by the host plant cell during endosymbiosis required the integration of two sets of biological membranes, the endoplasmic reticulum and the chloroplast envelopes, participating in the synthesis of galactolipid precursors for the photosynthetic membranes. Summary.

Chloroplast membranes contain high levels of the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG). Chloroplast membranes contain high levels of the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG). Chloroplast membranes contain high levels of the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG).

Chloroplasts treated with the lipase in the absence of bovine serum albumin lost 91% of their monogalactosyl diglyceride, 83% of their digalactosyl diglyceride, all of their phosphatidyl choline, but none of their sulfolipid 2007-09-01 · Membrane composition in chloroplasts and cyanobacteria is highly conserved, with monogalactosyldiacylglycerol (MGD) and digalactosyldiacylglycerol (DGD) representing the most abundant lipids. The genes encoding enzymes of galactolipid biosynthesis have been isolated from Arabidopsis.

A galactolipid lipase from primary bean ( Phaseolus vulgaris ) leaves has been used to partially deplete spinach chloroplast inner membranes of their galactolipids. Chloroplasts treated with the lipase in the absence of bovine serum albumin lost 91% of their monogalactosyl diglyceride, 83% of their digalactosyl diglyceride, all of their phosphatidyl choline, but none of their sulfolipid 2007-09-01 · Membrane composition in chloroplasts and cyanobacteria is highly conserved, with monogalactosyldiacylglycerol (MGD) and digalactosyldiacylglycerol (DGD) representing the most abundant lipids. The genes encoding enzymes of galactolipid biosynthesis have been isolated from Arabidopsis.

In our study, we used heterozygous plants of mgd1-2 and dgd1-2 mutants to show the role of uncharged galactolipids in the formation of the mature, photosynthetically active, thylakoid network.
