Figure 6. Cell envelope defects associate with the new pole.

a) New-pole-aligned cell width profiles of deformed, non-septated ΔmptA cells grown planktonically in LB medium. Cells were labelled with RADA and aligned new pole (bright) to old pole (dim) based on RADA labelling. b) New-pole-aligned RADA labelling profile of WT and ΔmptA cells grown planktonically in LB medium. c) Example fluorescence microscopy images of RADA-labelled WT and ΔmptA cells. np, the new pole; op, the old pole; PG, peptidoglycan.
