Cytokinetic ring tension is sufficient to curtail septum roughness without significantly affecting constriction rate. (A) Mean roughness of simulated septa versus tension, after fixing other parameters as described in supplementary material Table S1. Each point is the average over n=360 edges from 30 constrictions. Error bars indicate ±s.d.; the dashed line indicates the experimental mean septum roughness from constrictions of Fig. 2B, averaged over constrictions and times. (B) Simulated mean septum radii versus time for three values of ring tension, compared to a typical experimental constriction.
