Kin discrimination drives territorial exclusion during Bacillus subtilis swarming and restrains exploitation of surfactin.

Abstract excerpt

Swarming is the collective movement of bacteria across a surface. It requires the production of surfactants (public goods) to overcome surface tension and provides an excellent model to investigate bacterial cooperation. Previously, we correlated swarm interaction phenotypes with kin discrimination between B. subtilis soil isolates, by showing that less related strains form boundaries between swarms and highly...
