Microtubule numbers and length in wild type and mutant touch receptor neurons. Values are mean ± standard deviation for the number of neurons indicated in parentheses. Serial-section TEM data sets consisted of between 38 and 68 thin sections covering between 1.9 and 3.4 µm in length. Length is estimated from the number of microtubules per cross-section (${\displaystyle N}$), series length (a) and the number of endpoints (${\displaystyle T}$) detected in the series: ${\displaystyle l=2\cdot N\cdot a/T}$ (Chalfie and Thomson, 1979). A one-way ANOVA on the ranks (Kruskal-Wallis test) shows a significant effect (α = 0.05) of genotype on microtubule number (p=0.0465) and length (p=0.0420) in ALM, but no effect of genotype on microtubule number (p=0.827) and length (p=0.232) in AVM. *p<0.05 different from control, Mann-Whitney test.
