The pseudomonas aeruginosa motR gene involved in regulation of bacterial motility.
A mini-Tn5-Hg insertion mutant derived from Pseudomonas aeruginosa W51D (W51M1) was isolated in which mini-Tn5 insertion disrupted the motR gene showing that it forms part of the cluster involved in bacterial motility and chemotaxis. Characterization of the W51M1 motility behavior, and also of a PAO1 motR::mini-Tn5-Hg mutant, suggests that the product of the motR gene is a negative regulator of bacterial motility which controls the number of flagella per cell.
