Analysis of Chloroplast Lipid Biosynthesis

Most of the membrane lipids in the chloroplast are located in the thylakoid membrane. This thylakoid membrane is the site of the photosynthetic electron transport chain and constitutes a very large surface area in green plant tissue. The chloroplast is separated from the cytoplasm by a double envelope, and all molecules that are exchanged between the chloroplast and other cells must pass through the envelope at some point. The envelope is also the site of final assembly of major chloroplast lipids. The overall lipid composition of different chloroplast membranes was intensively studied as early as the mid-1980s. At the same time, many major membrane lipid biosynthetic pathways have been identified, with glycerolipids as the main structural components of thylakoids, and their synthesis involves two major pathways located in the plastid and endoplasmic reticulum (ER). With the advent of the post-genomic era, researchers have uncovered the in vivo functions of individual membrane lipids by cloning a large number of important chloroplast lipid biosynthesis genes from species such as the model plant Arabidopsis thaliana. The regulation of chloroplast lipid and precursor synthesis pathways and transport has always attracted much attention and has become a research hotspot.

Services

The lipid composition of thylakoid membranes is unique and highly conserved. They provide the structural substrate for the photosynthetic complex and are involved in the formation of the photosynthetic machinery during chloroplast biogenesis. Over the years, the team at Lifeasible has accumulated extensive experience in chloroplast lipidome analysis. Our scientists are dedicated to providing chloroplast lipid biosynthesis analysis services to analyze the biosynthetic pathways of monogalactosyldiacylglycerols (MGDG), digalactosyldiacylglycerols (DGDG), sulfoquinolosyl diacylglycerols (SQDG) and phosphatidylglycerol (PG).

We can characterize regulatory components of chloroplast lipid metabolism, including substrate preference and availability of enzymes, allosteric regulation of enzymes by lipids, protein-protein interactions affecting enzyme localization, activity or turnover, and transcriptional control of the chloroplast membrane proteome. Furthermore, we cloned a large number of important chloroplast lipid biosynthesis genes from Arabidopsis thaliana and spinach to reveal the in vivo functions of individual membrane lipids. We analyzed the following chloroplast lipid biosynthesis:

• Analysis of Chloroplast Monogalactosyldiacylglycerols Biosynthesis
• Analysis of Chloroplast Digalactosyldiacylglycerols Biosynthesis
• Analysis of Chloroplast Sulfoquinolosyl Diacylglycerols Biosynthesis
• Analysis of Chloroplast Phosphatidylglycerol Biosynthesis
