SNPs in genes involved phospholipid biosynthesis and that contribute to glycerol synthesis.

<p>Three possible routes to the production of glycerol in <i>E. coli</i> are shown along with corresponding gene names and SNPs. CV103 carries mutations that affect (A) phospholipid biosynthesis (B) the interconversion of glycerol-3-phosphate and glycerol and (C) the interconversion of glycerol-1-phosphate and glycerol. A red color denotes elevated monoculture transcript levels while grey denotes no change in transcript level. Stars (★) and corresponding text denote the location and type of particular SNPs. Consistent with strain representations in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004430#pgen-1004430-g001" target="_blank">Figure 1</a> light blue stars indicate ancestral mutations present in JA122, purple indicates SNPs in CV101, yellow indicates SNPs in CV103, green indicates those in CV115/116, brown indicates SNPs shared by CV101/CV103/CV115/CV116 and pink denotes SNPs shared by CV101 and CV115/116.
