Figure 1. Schematic representation of mycobacterial polar growth and establishment of bacterial poles.

Two division cycles (D1 and D2) are presented. The active biosynthesis of lateral peptidoglycan at the poles and biosynthesis of septal peptidoglycan at the future pole (septal poles) are symbolized with curved arrows. The old pole (in red) and the new pole (in blue); are both represented and refer to the first division event (D1).
