Sulfolipids are a class of lipids which possess a sulfur-containing functional group. An abundant sulfolipid is sulfoquinovosyl diacylglycerol, which is composed of a glycoside of sulfoquinovose and diacylglycerol. In plants, sulfoquinovosyl diacylglycerides (SQDG) are important members of the sulfur cycle.
Molecular mechanisms underlying extensive replacement of phospholipids by galactolipids and sulfolipids in Hakea prostrata during leaf development. Finnegan, P. & Giavalisco, P. Australian Research Council. 1/01/14 → 31/12/17. Project: Research
Here we report that a member of the Arabidopsis phospholipase D gene family (PLDZ2) is gradually induced upon Pi starvation in both shoots and roots. Start studying Complex Lipids and Sterols. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 2016-03-30 Proteaceae species in south-western Australia occur on severely phosphorus (P)-impoverished soils. They have very low leaf P concentrations, but relatively fast rates of photosynthesis, thus exhibiting extremely high photosynthetic phosphorus-use-efficiency (PPUE). Although the mechanisms underpinning their high PPUE remain unknown, one possibility is that these species may be able to … Galactolipids (MGDG and DGDG) and sulfolipids (SQDG) are key components of plastidic membranes, and play important roles in plant development and photosynthesis.
Summary. Galactolipids (MGDG and DGDG), sulfolipid and phosphatidylglycerol are the main constituents of plastid membranes. Glycerolipid biosynthesis requires first the assembly of glycerol and esterification by fatty acids at the sn-1 and sn-2 positions of the glycerol backbone.

All three of these lipids are made using a sphingosine backbone. Cerebrosides are sphingolipids with a single sugar head group, globosides have multiple sugars
1994, Stroebel et al. 2003, Guskov et al. 2009). Galactolipids (MGDG and DGDG) and sulfolipids (SQDG) are key components of plastidic membranes, and play important roles in plant development and photosynthesis.
2. Galactolipids and Sulfolipids in Plant Cells Galactolipids are in the internal membranes of chloroplasts. • Most abundant membrane lipids in biosphere • No phosphate. Phosphate is conserved for more critical roles. Sulfolipids are also in plant membranes. • They have a negative charge like phosphate.
Galactolipids and sulfolipids are characteristic plant membrane glycerolipids. Galactolipids are neutral amphipatic lipids.
DGDGs the expression of sulfolipid and galactolipid genes are. The galactolipids monogalactosyl and digalactosyl diacylglycerol occur in all higher plants and are the sulfolipid- and phosphatidylcholine-deficient mutants of the pur- The result of a quantitative comparison of the polar lipid c
