Expression of salA, nagR, and nagI genes during growth of strain DR1 on 2 mM 3,4-dihydroxybenzoate (34OH-BA), 3-hydroxybenzoate (3OH-BA), 4-hydroxybenzoate (4OH-BA), acetate, benzoate, gentisate, or salicylate. The results were obtained from three independent experiments and normalized to 16S rRNA gene expression.
