Figure 7. The novel cytoplasmic rings are associated with the assembly of Gammaproteobacteria motors with a stabilized stator ring.

  Slices through electron cryotomograms (left panels), central slices through STAs (middle panels), and schematic representations (right panels) of S. oneidensis ΔflgH and P. fluorescens illustrating the presence of the ~ 55‐nm cytoplasmic rings during the assembly of these motors (green arrows). Red dotted circles highlight the complexes in the cryotomograms slices. Scale bars are 50 nm for cryotomogram slices, 20 nm for the STA.
