(a) Schematic pathway of cardiolipin biosynthsis and volcano plots across related gene knockout strains. PA, phosphatidic acid. PG, phosphoglycerol. CL, cardiolipin. MLCL, monolysocardiolipin. (b) Schematic pathway of Co-enzyme Q6 biosynthsis and molecule abundance across related gene knockout strains. *, p-value < 0.05. **, p-value < 0.01. ***, p-value < 0.001. (c) Principal component analysis (PCA) of Δgene strains. (d) Volcano plot showing average fold-change in molecule abundances (mean log2[Δmho1/wild-type]) versus statistical significance, showing select functional groups (GO terms and lipid class) significantly (Benjamini-Hochberg adjusted p-value < 0.05) enriched in either upregulated or downregulated molecules. (e) Nearest neighbor covariance network for Mho1.
