Extended Data Fig. 3: Replicates of R. irregularis C2 plates show consistent travelling wave pattern.

(a) Spatial distribution of filament density (blue) and tip (red) density over three consecutive days (colour gradient, with dark colours going to lighter from day one to three). Shaded region corresponds to uncertainty in density estimates computed by extrapolating the ones obtained for the plate in the main text (see Methods). Profile shown at regular intervals separated by 30 h, while distance from origin is computed under the assumption of half circular colonization of the plate. (b) Speed of growing tips at the front over time. Black points are the average hyphal growth speed at the front of the colony at each timestep. Error bars represent mean ± s.e.m. Black line is the average of black points. (c) Saturation density as a function of ring radius. Each line corresponds to the linear fit across saturation value obtained by fitting a sigmoid to density curves for each replicate. (d) Growing tip density peak value as a function of ring radius. Each line corresponds to the linear fit across peak values obtained by fitting the derivative of a sigmoid to growing tip density curves for each replicate. (e) Additional examples of extracted networks. Each row represents different timepoints of the same replicate. Scale bar is 1 mm.
