FIG 7.

Comparative lipidomics between the wild-type (WT) and ΔBbHapX or ΔBbOle1 mutant strains. (A and B) Phospholipids might exist in their cationic (A) or anionic (B) forms. The intensity of the indicated molecule was quantified by mass spectrum. The ratios of WT to mutant were calculated as relative levels. BbHapX has a more significant effect on conidial phospholipid profiles than BbOle1. (C) Effects of exogenous phospholipids on the percentage of SYTOX-stained germlings. Phospholipid feeding significantly reduced the percentage of stained cells in both the ΔBbHapX and ΔBbOle1 mutant strains. Different lowercase letters on bars indicate significant differences in percentage of the indicated strain fed with different phospholipids. LPC, lysophosphatidylcholine; PC, phosphatidylcholine; PE, phosphatidylethanolamine; PI, phosphatidylinositol. Error bars: standard deviation.
