A fadD mutant of Sinorhizobium meliloti shows multicellular swarming migration and is impaired in nodulation efficiency on alfalfa roots.

Molecular microbiology - 1 Jan 2002

Soto María José, Fernández-Pascual Mercedes, Sanjuan Juan, Olivares José

Abstract excerpt

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...
