Figure 2: MTs perform pivoting and are highly dynamic during meiosis I.

From: Paired arrangement of kinetochores together with microtubule pivoting and dynamics drive kinetochore capture in meiosis I

Figure 2

(A) Time-lapse images and corresponding drawing of MTs at the time interval with the highest turnover. (B) Example of the length variation of three MTs over time. (C) Number of MTs as a function of time (mean ± SD, zygotes n = 23. The SD was computed assuming that the catastrophes obey a Poisson distribution.). Time 0 represents the frame when the first capture was observed. (D) Catastrophe rate as a function of MT length (mean ± SD, n = 69). The green line is a linear fit (kcat = α * L). (E) Time-lapse images and corresponding drawing of MTs that perform angular motion. (F) Dependence of the MTs angular diffusion coefficient on MT length (mean ± s.e.m., n = 70). Inset: mean squared angular displacement for MTs of length L = 1.49 ± 0.18 μm (mean ± s.e.m, n = 53).
