FIG. 5.
PilY1 functions genetically upstream of the SadC diguanylate cyclase. (A) Shown are representative swarms for the WT and the ΔsadC, ΔwspR, and ΔPA1107 DGC mutants carrying either the empty vector (left column) or the pPilY1His plasmid (right column). Plates contained arabinose at a concentration of 0.2%. (B) Swarms of the WT and ΔpilY1 mutant when carrying either the vector (left column) or pSadC expression plasmid (right column). Plates contained arabinose at a concentration of 0.2%.
