Fig. 1

Phenotypic suppression of gacA mutants in colony size, opacity and siderophore. Suppression in strain VCW2F5 (ΔgacA::Km) is visible on LBS agar as large opaque colonies, a single suppressor is identified by the red arrow, among the small translucent colony-type. Varying degrees of phenotypic suppression in spontaneously arising gacA mutant derivatives, compared to reference strains ES114 and VCW2F5, of opacity on LBS agar (left side), and siderophore levels observed as an orange halo on CAS agar (right side) of each paired picture. The three gacA parental strain genotypes are color coded as described in Table 1. csrA mutations are indicated below suppressor strains
