Abstract excerpt
Transposon insertions located 325 and 740 base pairs upstream of the transcriptional start site of the flhDC operon resulted in cells that initiated swarming 1.5h earlier than wild-type and exhibited a 2-2.5-fold greater swarming velocity. These mutants also failed to consolidate (de-differentiate) normally and did not form the characteristic bulls-eye pattern of concentric swarming rings on solid media. The...
