Violin plot representing difference in protein abundances of the ΔpilA adapted (s13) grown with formate and fumarate versus wild-type DL-1 in acetate and fumarate. Each violin represents the median log2 fold change difference of proteins within a functional pathway group in ΔpilA adapted (s13) mutants versus DL-1. Scales within each violin indicate 1st quartile, median and 3rd quartile values. The spread of the violin represents the distribution of the log2FC of each protein comparison
