Values represent the percent fold changes in lipids compared to neutral soil pH (6.8). Lipid class separation was done using hydrophilic interaction chromatography coupled to a high-resolution Orbitrap mass spectrometry. PE = phosphatidylethanolamine, PA = phosphatidic acid, PC = phosphatidylcholine, AGIcSiE = acylated glucosyl sitosterol, PG = phosphatidylglycerol, PS = phosphatidylserine, LPC = lysophosphatidylcholine, SiE = betasitosterol, PI = phosphatidylinositol, DGDG = digalactosyldiacylglycerol, CL = cardiolipin, MGDG = monogalactosyldiacylglycerol, DGDG = digalactosyldiacylglycerol, LPE = lysophosphatidylethanolamine, SQDG = sulfoquinovosyl diacylglycerol, LPG = lysophosphatidylglycerol.

Values of lipid classes were marked as bold.
