SinRR’ positively influences the expression of PaLoC genes.

<p><b>(A)</b> Quantification of toxins in parent R20291 and the <i>sinRR’</i> mutant complemented strains using toxins specific ELISA. The data shown are means ± standard errors of three replicates. Statistical significance was tested using one-way ANOVA, followed by Dunnett’s multiple comparisons test comparing values to the average of the parent with vector control (*** <0.0005 <i>p</i>-value). <b>(B)</b> Increased intracellular levels of c-di-GMP in the <i>sinRR’</i> mutant. Statistical analysis was performed using two-tailed <i>t</i>-test (* <0.05 <i>p</i>-value).</p>
