Figure 6.

Relations between tissue growth and variable microtubule responses to compression in the GFP–MBD line.

(a, b) The four indented meristems are ordered by increasing apparent growth. Apparent stiffness (a) and apparent growth (b) were deduced resp. from the slope of the approach curve of the indentation ramp (Figure 1c) and from the displacement of the stage during the 6 h 30 min compression (Figure 1e).

(c) Proportion of cells showing apparent bundling deduced from three visual analyses.

(d–k) Same indices as in Figures 4 and 5.
