Peer pressure from a Proteus mirabilis self-recognition system controls participation in cooperative swarm motility
Fig 5
The Δids strain is excluded during consolidation between periods of swarming.
(A) 1:1 co-swarms of Δids-GFP and wildtype-DsRed or (B) wildtype-GFP and wildtype-DsRed were analyzed for GFP-associated and DsRed-associated fluorescence over the course of outward migration and through progression of the swarm-consolidation cycle. Each data point indicates the proportion of GFP-producing cells measured at the swarm front at a given time after swarm emergence. Periods of active swarm expansion were determined by eye and are highlighted in gray. Three biological repeats were performed, and each is shown.
