Figure 4

Temporal sequence of swimming of fluorescently labeled P. aeruginosa (Δt = 60ms) showing (a) a hyperswarmer forward run with two spatially separate flagella, (b) a wild-type backward-to-forward run (white arrow indicates the turning time) (c) flagellar organization of wild-type and the two hyperswarmer clones (pictures are taken when bacteria are attached to glass, to enhance image quality). (d) There is no significant difference in speed between forward and backward runs for any strain, but hyperswarmers swim significantly slower than wild-type (p<0.001 by Kruskal-Wallis test). Dots represents median values of velocities and lower and upper bound represent respectively 25% and 75% percentile of velocities distributions.
