FIG 4.
Expression of fleQas attenuates AlgU-dependent downregulation of motility. Shown are P. syringae pv. tomato DC3000 cells with a wild-type (+) or mutant (−) fleQas promoter and containing AlgU expression (+) or empty vector (−). The diameter of the colony was measured after 44 h of incubation on swimming assay medium containing 0.3% agar (59). Means and standard deviations are shown for three biological replicates. The letters indicate Tukey-Kramer HSD mean comparison results; means labeled with different letters are significantly different.
