Fig 3. NrdR overexpression influences changes in bacterial morphology.

Fig 3

(A) Colony morphology of WT, ΔNrdR and OE-NrdR E. coli strains grown on LB medium. (B) Magnification (×100) of E. coli strains. Overexpression of NrdR resulted in bacterial aggregates (red arrows) and coccobacilli (short rods; green arrows). (C) Transmission electron microscopy of the WT, ΔNrdR and OE-NrdR E. coli strains at high magnification (magnification, ×21,000). Differences in flagella and cell walls among the E. coli strains can be observed.
