Figure 2B shows that in the hilA hilD mutant , HilD overproduction induces expression of sipA , whereas expression of orgA remains unaffected .
Figure 2B shows that in the hilA hilD mutant , HilD overproduction induces expression of sipA , whereas expression of prgK remains unaffected .
Figure 2B shows that in the hilA hilD mutant , HilD overproduction induces expression of sipA , whereas expression of prgH remains unaffected .
In addition , HilD directly activate sipA in non-HilA dependent manner .
