FIGURE 4:

Loss of DRC3 affects flagellar waveform. (A) Repre­sentative flagellar waveforms of WT, drc3, and DRC3-R cells. Waveforms of at least six free-swimming cells were analyzed for each strain; cells were observed over 2–10 beat cycles. For each cell type, cis- and trans-flagella from the same digital image have the same color; tracings of different colors are not necessarily from the same beat cycle. Flagellar length is not consistent through the beat cycle because the flagellar tip was sometimes out of focus. (B) Schematic diagrams illustrating typical flagellar beat envelopes for the WT and the drc3 mutant. The drc3 cells have a smaller beat envelope.
