Inherited flagellar structures coordinate the onset of swimming among related E. coli cells
Bacteria commit to costly behaviors before they can benefit from them. In Escherichia coli, flagellar synthesis is expensive, yet the genes are expressed in stochastic pulses and only a small minority of pulses result in motility. Despite this noise, we find that lineage-related cells begin swimming at similar times, in groups of two to eight cells. Rare, high-amplitude pulses commit a single…
