Fig. 5From: The effect of ArcA on the growth, motility, biofilm formation, and virulence of Plesiomonas shigelloidesArcA controls the motility of P. shigelloides by directly binding the promoter regions of flaK, rpoN and cheV genes. A The EMSA of phosphorylated ArcA protein and the flaK promoter. B The EMSA of phosphorylated ArcA protein and the rpoN promoter. C The EMSA of phosphorylated ArcA protein and the cheV promoter. The concentration of phosphorylated ArcA protein was increased gradually with the non-phosphorylated ArcA as a negative control (non-ArcA-P). D The mRNA level of flaK, rpoN and cheV of the WT and ΔarcA mutant. Significant differences were indicated by asterisks (**P < 0.01)Back to article page
