Parallel evolution suggests genes that may contribute to TGC resistance.

<p>Venn diagrams represent (A) the number of mutations, (B) nsSNPs, or (C) genes that were observed in the individual trials or combined (Trial 1, green; Trial 2 blue). (D) Genes mutated in both trials were plotted based on the number of mutations in the gene and the percentage of clones that contained at least one mutation in the gene. False noise was added to the number of mutations in each gene to separate the spots. <i>P</i> values were calculated using Fisher’s Exact Test. Genes with <i>p</i> values < 0.001 are labeled. Due to its role in TGC resistance, <i>rpsJ</i> was also labeled.
