FIG. 3.
σB-dependent operons in lineage II but not in lineage I. The diagrams show two putative operons that appear to be σB dependent in the lineage II wild-type strain but not in the lineage I wild-type strain. (A) Operon consisting of lmo0398, lmo0399, lmo0400, lmo0401, and lmo0402. Genes in this operon were flanked by Rho-independent terminators, which are indicated by stem-loop structures. The numbers below each gene indicate the fold change in the transcript level in the parent strain compared to that in the ΔsigB strain for each lineage; bold type indicates values that are significantly different (≥1.5-fold change; adjusted P value, <0.05). The values in parentheses are the hybridization index (expressed as a percentage) for each strain; some hybridization indices could not be calculated as BLAST results found no match because the genomes are not complete yet. (B) Fold changes (significantly differentially expressed genes indicated by boldface type) and hybridization indices for the σB-dependent putative operon comprised of lmo2164, lmo2163, lmo2162, lmo2161, lmo2160, lmo2159, and lmo2158.
