Figure 2From: The PhoBR two-component system regulates antibiotic biosynthesis in Serratia in response to phosphateThe effects of a pstS mutation on secondary metabolism and QS are occurring via PhoBR. (A) Pig, (B) Car and (C) AHL production were measured from WT, pstS mutant (ROP2), phoR mutant (BR1), phoB mutant (BR9), pstS, phoR double mutant (PCF60) and pstS, phoB double mutant (PCF59) cells. Production was assayed from cells grown to early stationary phase in LB.Back to article page
