Root colonization assays of rice rhizosphere P. aeruginosa strain PUPa3 and QS mutant derivatives in four independent experiments (A to D). PUPa3, P. aeruginosa PUPa3 wild-type strain; LASI, lasI mutant; LASR, lasR mutant; RHLI, rhlI mutant; DMI, lasI rhlI double mutant; DMR, lasR rhlR double mutant; RSAL, rsaL mutant. The colonization of the wild-type strain was significantly higher than that of all QS mutant strains.
