Med15B affects the membrane phospholipids of C. glabrata. Changes in the content of phospholipids in the parent (HTUΔ), med15BΔ, and HTUΔ/CgMED15B strains at pH 6.0 (A) and pH 2.0 (B). Abbreviations: PA, phosphatidic acid; PC, phosphocholine; PE, phosphatidylethanolamine; PS, phosphatidylserine; PG, phosphatidylglycerol; PI, phosphatidylinositol. The experiments were performed in biological triplicates. Error bars indicate the standard deviations.
