Cell division in bacteria that display polar growth. (A) FtsZ (purple foci) in A. tumefaciens remain localized at the pole after cell division and likely facilitate polar elongation specifically at the new pole (red line). Subsequently FtsZ relocates to the mid-cell site (purple ring) to assemble the divisome and mediate cell division. (B) Cells of both C. glutamicum and M. tuberculosis (labeled “Actinobacteria”) undergo uneven growth at cells poles with older poles exhibiting faster growth than the new pole.
