FIG. 1.
Branches and abnormalities in E. coli ftsZ84 ΔPBP 5. Cells grown at 30°C were washed, diluted into LB medium (0.5% NaCl), and incubated at 37°C until the culture reached mid-log phase. Arrowheads indicate some of the branches and morphological abnormalities. The image is a composite of cells from different fields. Bar, 10 μm.
