a Biomass in WT swarming tendrils over time (12 tendrils). Line indicates median data. Full range of data shaded. Data has been smoothed with a moving window of 5 for visualization. [Inset] Image of swarm. Scale bar 1 cm. b Biomass and GFP distribution in tendrils 3 cm in length. Gray bar indicates swarm center. Shaded regions indicate the full range of the data. Middle line indicates median data. c [Inset] Coloration legend. Image of a WT swarm tendril with relevant region delineations indicated. [Main Panel] Promoter activity in each pixel with respect to growth rate during the corresponding time interval. Red coloration indicates that the pixel was in the tendril tip, the 0.86 mm closest to the front edge of the tendril. d, e Same data as in (c), pixels in cyan originated in the swarm center, green pixels originated between the swarm center and tendril edge. c–e Show data for a representative tendril.
