Two separate regulatory systems participate in control of swarming motility of Serratia liquefaciens MG1

J Bacteriol. 1998 Feb;180(3):742-5. doi: 10.1128/JB.180.3.742-745.1998.

Abstract

Swarming motility of Serratia liquefaciens MG1 requires the expression of two genetic loci, flhDC and swrI. Here we demonstrate that the products of the flhDC operon (the flagellar master regulator) and the swrI gene (the extracellular signal molecule N-butanoyl-L-homoserine lactone) are global regulators which control two separate regulons.
