Salmonella flgG point mutations produce filamentous rod structures whose lengths are determined by FliK. FliK length variants produce rods with lengths proportional to the corresponding FliK molecular size, suggesting that FliK controls the length of not only the hook but also the rod by the same molecular mechanism.
