Swarming is a form of bacterial translocation that involves cell differentiation and is characterized by a rapid and co-ordinated population migration across solid surfaces. We have isolated a Tn5 mutant of Sinorhizobium meliloti GR4 showing conditional swarming. Swarm cells from the mutant strain QS77 induced on semi-solid minimal medium in response to different signals are hyperflagellated and about twice as long as wild-type cells. Genetic and physiological characterization of the mutant… CONTINUE READING
