Effect of low Mg2+ (8μM) on the system output (measured by the surrogate marker dEGFP Experimental plot showing the system behavior as observed for time of 60 mins when the cells were in a culture of low (8μM) magnesium medium. It shows how in low magnesium, the PhoPQ pathway is activated (as shown by increase in concentration of phoPp).
