Figure 2. Cones are associated with chemosensory arrays, ribosome-excluding zones and filament bundles. Tomographic slices show side (A) and top (B, C) views of cones (c) in three cells, highlighting associated chemosensory arrays (ca), ribosome-excluding zones (rez) and filament bundles (f). For a slice-by-slice view through the tomogram shown in (A), see Movie S1. (D) and (E) show different views of a 3D segmentation of the structures shown in (C), with the conical structure in blue and the filament bundle in red. s, S-layer; m, membrane; a, archaellum; o, other filaments. Scale bar 100 nm (applies to A-C); segmentation not to scale.
