Effect of FlgE and FliK over-expression on the hook length control in the presence and absence of FliH and FliI. Electron micrographs of HBBs and histograms of hook length distribution of (a) SJW1103 transformed with pNM001 (WT/pFlgE), (b) SJW1103 carrying pMMIK100 (WT/pFliK), (c) MMHI0117 harbouring pNM001 (∆fliHI flhB*/pFlgE) and (d) MMHI0117 harbouring pMMIK100 (∆fliHI flhB*/pFliK). Scale bar, 100 nm.
