Figure 5

Comparison of transcriptional profiles for sample 2 (4.5 h, black line) and sample 4 (14 h, red line), normalized to the gene length and genome-wide total number of unambiguously mapped reads for that sample. Shown are an ~5.4 kb segment surrounding the gap-pgk-tpi glycolytic gene operon (Cbei_0597-0600) and an ~1.2 kb segment surrounding the cotJC-cotJB (Cbei_2069-2071) sporulation gene operon. Specific genes are indicated with arrows, whose colors indicate the COG functional class of genes as defined in Additional file 1 Figure S1. Below each gene is the expression level fold change that was measured by microarray data for equivalent samples (5 h vs. 13 h in Shi and Blaschek [13]; microarray data for Cbei_2071 are not available).
