Regulation of STM3611 by CsrA. A) Effect of a csrA mutation on STM3611 and STM1798 mRNA levels in a fliA deficient background. RNA was isolated from bacterial cultures grown at 37 °C in LB medium with 0.1 % arabinose to OD600 1.5. mRNA levels of STM3611 and STM1798 were measured by quantitative Real-Time RT PCR in the csrA mutant MAE125 and the fliA csrA double mutant MAE1476 (fliA csrA). The values represent means with standard deviations (** P < 0.01). B) Schematic model depicting the inferred direct and indirect regulation of STM3611 by CsrA.
