Cellular lipids were extracted from three species of Oomycete plant pathogens (Pythium ultimum, Phytophthora infestans, and Ph. capsici) and analyzed via normal-phase high-performance liquid chromatography with flame-ionization detection. The most abundant polar lipids in each of the three species were the polar membrane lipids, phosphatidylethanolamine (PE), phosphatidylcholine, and a phosphosphingolipid that eluted soon after PE. Structural analysis via mass spectrometry and nuclear magnetic… 
Lipids of Haliphthoros philippinensis: An oomycetous marine microbe
The effects of several cultivation variables on growth and EPA production by this species were investigated and glucose and sodium glutamate were the most efficient carbon and nitrogen sources for growth, respectively.
Identification of Lipid Markers of Plasmopara viticola Infection in Grapevine Using a Non-targeted Metabolomic Approach
This work uses a mass spectrometry-based non-targeted metabolomic approach to identify potential Plasmopara-specific metabolites, which led to the characterization and structural elucidation of compounds belonging to three families of atypical lipids, which are not detected in healthy grapevine tissues.
Lipidomic analysis of Toxoplasma gondii reveals unusual polar lipids.
Analysis of the polar lipids of Toxoplasma gondii by electrospray ionization tandem mass spectrometry provides a detailed picture of the lipid molecular species of this parasitic protozoan and will assist in elucidation of metabolic pathways for lipid biosynthesis in this important human pathogen.
Sphingolipids in Bacteria and Fungi
Abstract Sphingolipids constitute a distinctive group of membrane lipids characterized by a long-chain (monounsaturated), di-hydroxy amine structure (sphingosine). Sphingolipids are essential
Cell Wall Polysaccharide Synthases Are Located in Detergent-Resistant Membrane Microdomains in Oomycetes
The results presented here are consistent with a function of lipid rafts in cell polarization and as platforms for sorting specific sets of proteins targeted to the plasma membrane, such as carbohydrate synthases.


Structural investigations and biological activity of inositol sphingophospholipids from Phytophthora capsici.
Inositol sphingophospholipids that protect pepper against pathogen have been isolated by chromatographic methods from the mycelium of Phytophthora capsici by chemical methods and mass spectrometry.
Production of the polyunsaturated fatty acids arachidonic acid and eicosapentaenoic acid by the fungus Pythium ultimum.
Several strains of species of the fungal genus Pythium, and of Phytophthora cinnamomi, were screened for content of the polyunsaturated fatty acids (PUFAs) arachidonic acid (AA) and eicosapentaenoic acid (EPA) to establish alternative sources of these PUFAs, which are of importance in human nutrition.
Isolation and characterization of inositol sphingophospholipids from Phytophthora parasitica Dastur
It is shown that P. parasitica Dastur synthesized four major classes of compounds with molecular weights of Mr=751, 807, 835, and 849 containing the 16:1 base and the N-acyl group, and the relative abundance of the different ISPL is dependent on growth conditions.
Analysis of intact hopanoids and other lipids from the bacterium Zymomonas mobilis by high-performance liquid chromatography.
This new chromatographic method represents the first technique for the analysis and purification of intact hopanoid analysis and should be useful for theAnalysis and purifying of hopanoids from other bacterial species.
The phosphoinositol sphingolipids of Saccharomyces cerevisiae are highly localized in the plasma membrane.
The results suggest that one or more essential functions of these lipids is in the plasma membrane, and sphingolipids may be useful chemical markers of the plasma membranes of S. cerevisiae.
Reassessment of the role of phospholipids in sexual reproduction by sterol-auxotrophic fungi
The levels of sterols required for the maturation of oospores with appropriate phospholipid medium supplementation suggest that these compounds are necessary only for the sparking and critical domain roles previously described in other fungi.
