Formation of oxidized phosphatidylinositol and 12-oxo-phytodienoic acid containing acylated phosphatidylglycerol during the hypersensitive response in Arabidopsis

Glycerolipids obtained from Arabidopsis leaf tissue undergoing the hypersensitive response triggered by the bacterial effector protein AvrRpm1 were analyzed by a new reverse phase LC-MS/MS method. Among the lipids discovered by untargeted phospholipid profiling were phosphatidylglycerol species acylated with 12-oxo-phytodienoic acid.
