Schematic representation of model predictions for septin filaments at the bud neck of S. cerevisiae. a Filaments on a spherical geometry arranged radially. b Filaments on a barrel-like geometry arranged along the height of the barrel. c At the onset of the constriction, single filaments are arranged circumferentially while double filaments are arranged perpendicular to the single filaments. d Upon further constriction, all filaments at the center of the bottleneck are arranged circumferentially while the organization remains the same at the edges. e Under extreme constriction, filament bundles appear
