Figure 4.

Evolution of genes upregulated when grown on saturated or unsaturated fatty acids. Genes upregulated by at least 1.5 standard deviations are indicated here. a) Genes expressed under palmitic acid but not oleic or linoleic (genes expressed in saturated fatty acid conditions). b) Genes expressed under linoleic or oleic acid but not palmitic (genes expressed under unsaturated fatty acid conditions). c) The ratio of the phylogenetic profiles for genes expressed under palmitic and linoleic acid, normalized by genome size.
