Figure 2
Neighbour-joining tree showing the phylogenetic relationships among 28 strains. NJ tree is based on 55 core genes present in all genomes. The genomes are grouped into three main clusters (1) 10 Lysinibacillus strains and one Bacillus spp, (2) B. subtilis and (3) B. cereus group. Within the Lysinibacillus / Bacillus spp cluster, the toxic L. sphaericus strains form a single well defined tight cluster (marked with box with dotted line) whereas the non toxic strains (marked with arrows) are less well defined. Support for clades was assessed using 1,000 bootstraps.
