FIG 6.

RsaM1 negatively regulates the transcription of btaR1, but btaR2 transcription is not modulated by RsaM2. The relative transcript levels of btaR1 (A), btaR2 (B), and btaR3 (C) were assessed by qRT-PCR in cultures of the wild-type and the rsaM1 and rsaM2 mutant strains of B. thailandensis E264. The results are presented as relative quantification of transcription of the gene compared to the wild-type strain, which was set at 100%. The values are means ± standard deviations (error bars) for three replicates. Values that are significantly different are indicated by asterisks as follows: **, P < 0.01. Values that are not significantly different (ns) are also indicated.
