External force enhances the probability for pilus elongation. (a) Length change of a single pilus at 15 and (b) at 100 pN. Negative length change corresponds to pilus retraction. (ce) Probability for pilus elongation (white), pausing (gray), and pilus retraction (black) for (c) MS11, (d) MS11pilT oe (increased PilT), and (e) MS11pilT ind (decreased PilT). The corresponding data set contains 465 retraction curves. Error bars represent SD obtained from statistical resampling.
