FIG 2.

Viability on surfaces and generation times in liquid are unaltered when D and E are noncognate. (A) Viable cells per swarm colony over time on swarm-permissive agar surfaces. D and E variants produced by the different strains are indicated in panel B. Error bars, standard deviations (n = 4). (B) Generation times during logarithmic growth in liquid medium (n = 6). Boxes range from the 25th to the 75th percentile, lines within boxes indicate medians, and whiskers indicate minima and maxima.
