1 presented in more detail in Additional File 8.

2 genes in bold were also found to be different in the proteome analysis detailed in Additional File 5. Underlined genes were more highly expressed during all stages of growth in M600 relative to the bldA mutant. Q-RT-PCR was performed with the 16 RNA samples from replicate 3 time courses, using specific primers and probes covering 50–150 bp, for each of the following genes: SCO4295, SCO5013, SCO6808, and SCO7657; five genes up-regulated in the bldA mutant – SCO3088, SCO3285, SCO3286, SCO5166, SCO6958; the TTA-containing gene SCO6638; and the ribosomal protein genes SCO4648, SCO4702, SCO4705, SCO4717. See Additional File 2 for these results.
