Figure 7.

Locations in genome of genes determined by microarray analysis to have changes in transcript abundance. mRNA content from cells using benzoate vs. acetate as the sole electron and carbon source was compared, with soluble Fe(III) as the terminal electron acceptor in both cases. Distance from the horizontal line represents fold change in transcript levels, with only those genes with a two-fold or greater change and a significance of p ≤ 0.01 shown. The thick black bar represents the large aromatics island Gmet_2037-Gmet_2284.
