Figure 6.

Analysis of the counterbend images yields the ratio of shear stiffness to flexural rigidity of the axoneme (β² = k_s/EI); individual estimates of β² are shown for (a) wild-type (WT) and pf3; cnk11-6 flagella, and (b) WT and pf13A flagella. A statistically significant difference exists (p = 0.0012) between wild-type (β² = 0.111 ± 0.054 μm⁻²) and the pf3; cnk11-6 mutant (β² = 0.041 ± 0.012 μm⁻²). The difference between WT and pf13A (β² = 0.061 ± 0.028) is also statistically significant (p = 0.012). To see this figure in color, go online.
