Fatty acid composition of sterol esters and acylated sterol glucosides determined by Q-TOF MS/MS. A: Sterol esters; (B) acylated sterol glucosides. Sterol lipids were isolated from leaves of WT and pho1 mutant plants grown on soil and from leaves and roots of WT plants grown on synthetic medium with or without phosphate. Bars show acyl composition as means ± SD of five measurements. Data were confirmed by a second independent biological experiment. Values that are significantly different from those of the WT or phosphate-containing control and higher than 2 mol% are indicated by an asterisk (according to Student's t test; P < 0.02).
