Differential expression of M. smithii adhesin-like proteins (ALPs). Members of selected ALP OGUs with strain-specific differences in their expression profiles (A) and strain-specific, as well as OGU-associated, differences in their sensitivity to levels of formate during midlog phase growth (B). OGUs 112, 412, 827, and 208 exhibit strain-specific differences in their expression irrespective of formate concentration (one-way ANOVA, P < 0.0001), whereas OGUs 226, 287, 18, 133, and 37 contain at least one representative that is significantly regulated by formate concentration. Mean values ± SEM are plotted (n = 6 replicates per condition). * indicates a ≥2-fold difference, PPDE ≥ 0.97 (Dataset S1, Table S7).
