Figure 2.

Real-time PCR expression ratios of selected genes. Bacteria were cultured in acid or base, or at pH 7.0, with aeration (○) or under oxygen limitation (●) (see Methods). For each gene, expression levels are shown for amplified message in acid or base, relative to the level at pH 7 with aeration.
