Fig. 4. Disruption of MT turnover affects the tension-induced MT band formation.
a–l Results of parameter estimation (a–c, g–i) and comparisons of tension and MT band pattern (d–f, j–l) for the oryzalin-treated zygote shown in Fig. 2e (a–f) and the taxol-treated zygote shown in Fig. 2i (g–l). a, g Comparisons of cell growth rate (dL/dt) and cell tip radius (re) between time-lapse observation data (Data; magenta) and reconstructed model zygote (Model; green). b, h Estimated turgor pressure (P) and extensibility range (lg). c, i Comparisons of the contour dynamics of Data and Model. d–f, j–l Calculated circumferential surface tension (σθ) (d, j), its time change (Dσθ/Dt) (e, k), and observed MT signal intensity (f, l) (Supplementary Movies 6, 7). Magenta lines and crosses in (l) indicate the MT bands and their centers. No MT band was detected in oryzalin-treated zygotes (Supplementary Movie 2). Source data are provided as a Source Data file.
