Genetic Regulation of Unsaturated Fatty Acid Composition in C. elegans
Figure 5
Fatty Acid Composition of the Δ9 Desaturase Mutants
(A−C) There is little change in fatty acid composition for fat-5 (A), fat-6 (B), and fat-7 (C) mutants compared to wild-type worms when grown under standard growth conditions with OP50 E. coli as the sole food source.
(D−F) Axenic growth conditions for wild-type worms and fat-5 (D), fat-6 (E), and fat-7 (F) mutants reveal major changes in fatty acid composition for fat-5 and fat-6 mutants compared to wild-type worms. In all graphs relative abundance of selected fatty acid species is expressed as percentage of total fatty acid as determined by gas chromatography analysis. Error bars represent the standard error. *significant difference from wild type, p < 0.01
