This might suggest that the absence of galactolipids may create a similar environment, in which PLP is malfunctioning. One possibility is that PLP may only function properly by localizing in the correct plasma membrane microdomain, which might directly or indirectly …

However, galactolipid functions that rely on … 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. Galactolipids (MGDG and DGDG) and sulfolipids (SQDG) are key components of plastidic membranes, and play important roles in plant development and photosynthesis. In this study, the whole families of MGD, DGD and SQD were identified in maize genome, and were designated as ZmMGD1-3, ZmDGD1-5 and ZmSQD1-5 respectively.

Historically, the roles of galactolipids have been studied mainly in relation to photosynthesis, and recent advances in molecular biology with Arabidopsis and other model organisms have revealed an essential role of galactolipids in photosynthesis. The GALC gene provides instructions for making an enzyme called galactosylceramidase. Through a process called hydrolysis, this enzyme uses water molecules to break down certain fats called galactolipids, which are found primarily in the nervous system and kidneys. In Arabidopsis leaves, under standard conditions, the enzymes MGD1 and DGD1 provide the bulk of galactolipids, necessary for the massive expansion of thylakoid membranes. Under phosphate limited conditions, plants activate another pathway involving MGD2/MGD3 and DGD2 to provide additional DGDG that is exported to extraplastidial membranes where they partly replace phospholipids, a phosphate-saving mechanism in plants. Some of these functions include insulation, cushioning, energy storage, and making cell membranes.

MGDG and DGDG in these processes. Recent advances in understanding the functions of galactolipids as key facilitators of various membrane-associated processes in etioplasts and chloroplasts provide important insights into the complex processes of thylakoid membrane development and photosynthetic activation in plants.

Until recently, our concept of GalC and sulfatide functions had been principally defined by immunological and chemical perturbation studies that implicate these lipids in oligodendrocyte differentiation, myelin formation, and myelin stability. Recently, however, genetic studies have allowed us to re-analyze the functions of these lipids.

Oxygenic photosynthesis in cyanobacteria and plants depends on the presence of galactolipids. The ratio of the two galactolipids carrying one or two galactoses in the head group is crucial for the maintenance of membrane integrity during stress.

Oxygenic photosynthesis in cyanobacteria and plants depends on the presence of galactolipids. The ratio of the two galactolipids carrying one or two galactoses in the head group is crucial for the maintenance of membrane integrity during stress. The galactosylceramidase enzyme functions to remove galactose from galactosylceramide, galactosylsphingosine, and other galactolipids. Both galactosylceramide and galactosylsphingosine have potent proinflammatory effects, and the latter molecule causes oligodendrocyte and Schwann cell death.

The isolation of the genes involved in the biosynthesis of MGDG and DGDG, and the identification of galactolipid-deficient Arabidopsis mutants has greatly facilitated the analysis of galactolipid biosynthesis and function. Until recently, our concept of GalC and sulfatide functions had been principally defined by immunological and chemical perturbation studies that implicate these lipids in oligodendrocyte differentiation, myelin formation, and myelin stability. Recently, however, genetic studies have allowed us to re-analyze the functions of these lipids. Galactolipids, mainly monogalactosyl diglycerides and digalactosyl diglycerides are the main lipids found in the membranes of plants, algae and photosynthetic microorganisms like microalgae and cyanobacteria. As such, they are the main lipids present at the surface of earth.

Galactolipids are a type of glycolipid whose sugar group is galactose. They differ from glycosphingolipids in that they do not have nitrogen in their composition.

These vary from a function as a carbohydrate reservoir to a function in the electron transport chain in photosynthesis. This review is intended to summarize the present knowledge of the synthetic and degradative chemistry of the galactolipids and of their functions … These galactolipids are synthesized in the chloroplast envelope membrane through the concerted action of galactosyltransferases, the so-called 'MGDG synthases (MGDs)' and 'DGDG synthases (DGDs),' which use uridine diphosphate (UDP)-galactose as donor.
