Fig. 3. Kin discrimination mediates fitness via cell lysis.
a Swarm assay on B agar. The left and right panels are scanning electron microscopy micrographs taken at the meeting point of kin strains PS-216Sp and PS-13Cm (blue, left) and non-kin strains PS-216Sp and PS-196Cm (red, right). b Relative fitness of strains in kin pairings (blue) and non-kin pairings (red) (n = 3 biologically independent experiments, each n performed in three technical replicates (9 data points)). See Table 2 for strain abbreviations. All experiments (in a and b) were performed in three biologically independent experiments. Data are presented as mean values ±SD and error bars represent SD of the mean values (n = 3).
