The alleles of fliC from Pto strains T1, DC3000, K40 and Pcal ES4326 reconstitute motility in Pto DC3000δfliC. (a) Swim size on a KB swim plate (0.3% agar) 2 d following toothpick inoculation with wild-type Pto DC3000 (wt), Pto DC3000δfliC with an empty vector (EV) or Pto DC3000δfliC complemented with the indicated alleles of fliC. (b) Quantification of swim size from 8 replicate plate. Error bars represent ± SE. Letters indicate significant differences at the 0.05 alpha level in an unpaired Student’s t-test. Similar results were obtained in 3 independent experiments.
