Model of DivIVA dynamics in B. subtilis. During cytokinesis DivIVA rings at constricting septa collapse into foci/patches (Eswaramoorthy et al., 2011). Exponentially growing B. subtilis cells redeploy at least a fraction of DivIVA molecules from old division sites (cell poles) to nascent septa (broken white lines). Only in non-dividing cells DivIVA is clearly seen as accumulation at both cell poles.
