The Rcs system is necessary for repression of hilA expression by acetate and yeast extract in a ΔhilE mutant. The figures show hilA expression in ΔrcsBC mutant (A) and ΔrcsBC ΔhilE mutant. Expression was determined by measuring β-galactosidase activity using transcriptional fusions of the hilA promoter to LacZ during growth in TB medium with the specified amount of yeast extact added. Sodium acetate was added at a concentration of 10 mM. Results show the mean and standard deviation from three biological replicates
