Complementation of pabAa pabAb function by Corynebacterium diphtheriae DIP1790. Complementation of E. coli pabAa pabAb double mutant BN1163 by a pLOI707HE plasmid harboring DIP1790 from Corynebacterium diphtheriae on M9 minimal medium with or without pABA. Arabidopsis ADCS was included as a positive control. 1, pLOI707HE::ADCS; 2, pLOI707HE::DIP1790; 3, pLOI707HE alone. The medium contained IPTG and appropriate antibiotics.
