  • The data represent the average microtubule contact times ± sd (n = microtubules) after microtubule zippering or catastrophic collisions.

  • a Comparison between the contact times for zippering and catastrophically colliding transverse microtubules: P-value ∼ 0.0001 (Mann-Whitney test).

  • b Comparison between the contact times for zippering transverse and longitudinal microtubules: P-value ∼0.004 (Mann-Whitney test).

  • c Comparison between the contact times for zippering and catastrophically colliding longitudinal microtubules: P-value ∼0.001 (Mann-Whitney test).
