RpfC positively affects the expression of hrpX in XCM1 minimal medium. β-Glucuronidase (GUS) activities of hrpG and hrpX promoter-gusA reporters in the rpfC mutant and the wild-type backgrounds. Strains were cultured in XCM1 medium for 24 h, and GUS activities were then determined by measurement of optical density at 415 nm (OD415) using ρ-nitrophenyl-D-glucuronide as substrate. Data are mean ± standard deviations (SD) of triplicate measurements. The experiment was repeated twice and similar results were obtained. **, t-test, p < 0.01
