TL;DR: Surfactins were mainly located in the central mother colony (the site of initial inoculation), in a ‘ring’ surrounding the pattern and along the edges of the dendrites, whereas in the ring surrounding the swarm community and between dendrite, surfactins with longer fatty acyl chain lengths were found.

TL;DR: It is established that distinct early stages of dendritic swarming can be clearly defined, and that they are amenable to genetic analysis, which indicates a specific migration defect in the phrC mutant that could not be trans-complemented by CSF in a mixed swarm.

TL;DR: A model for this swarming process is discussed, emphasizing the importance of population density and of the complementary roles of packs of swarmers driving dendrite extension, while non-mobile cells in the stems extend dendrites by multiplication.

TL;DR: The crystal structure of CPGA(YloQ) suggests a role as a translation initiation factor and the possibility that CpgA is involved in the translation of a subset of proteins, including some required for shape maintenance, is discussed.

TL;DR: In situ, in situ that DNA replication, protein translation and peptidoglycan synthesis are primarily restricted to the swarmer cells at dendrite tips, showing that swarmers not only lead the population forward but continue to multiply as a source of all cells in the community.
