Expression of hrpB‐lacZYA, hrpG‐lacZYA and prhG‐lacZYA with prhP deletion. Ralstonia solanacearum cells were grown in nutrient‐rich or hrp‐inducing media to an OD₆₀₀ of about 0.1 and subjected to enzyme assay. Mean values from all four biological replicates were averaged and presented with SD (error bars). Statistical significance between the prhP mutant (ΔprhP) and parent strains (WT) was assessed using a post hoc Dunnett test following ANOVA. Significance level: ** indicates P < 0.01.
