    Architecture of the ring formed by the tubulin homologue FtsZ in bacterial cell division

    Piotr Szwedziak et al.
    The architecture of the bacterial cytokinetic ring in cells and in artificial liposome reconstitutions has been described using electron microscopy, leading to a mechanism of constriction.

    General principles for the formation and proliferation of a wall-free (L-form) state in bacteria

    Romain Mercier et al.
    A wide range of bacterial species can switch into a cell wall-free state that does not require the FtsZ-based division machinery to proliferate.

    Lateral interactions between protofilaments of the bacterial tubulin homolog FtsZ are essential for cell division

    Fenghui Guan et al.
    Structural and functional approaches unambiguously revealed physiologically relevant lateral interactions between FtsZ protofilaments.

    Reconstitution of self-organizing protein gradients as spatial cues in cell-free systems

    Katja Zieske, Petra Schwille
    A minimal cell-like system with defined geometry has been used to investigate the establishment and spatial control of a protein gradient that positions the bacterial cell division machinery.

    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor et al.
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

    Coordination of peptidoglycan synthesis and outer membrane constriction during Escherichia coli cell division

    Andrew N Gray et al.
    The protein CpoB regulates PBP1B activity in response to the Tol energy state, which facilitates feedback and synchronicity between envelope constriction processes during Gram-negative bacterial cell division.

    An essential Staphylococcus aureus cell division protein directly regulates FtsZ dynamics

    Prahathees J Eswara et al.
    GpsB in Staphylococcus aureus directly regulates the central cell division protein FtsZ, a different function from that assigned for GpsB in other closely related organisms.

    Surface-to-volume scaling and aspect ratio preservation in rod-shaped bacteria

    Nikola Ojkic et al.
    Rod-shaped bacteria preserve their aspect ratios and surface-to-volume scaling by maintaining a homeostatic balance between the rates of cell elongation and division protein synthesis.

    Unified quantitative characterization of epithelial tissue development

    Boris Guirao et al.
    A new approach measures the respective participations of elementary cell behaviors – such as cell division, intercalation, shape change and death – in the shaping of animal tissues.

    Bacterial symbiont subpopulations have different roles in a deep-sea symbiosis

    Tjorven Hinzke et al.
    Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.
