Comparison of genetic organizations of the three genotypes in the versatile genomic region. The habitat-unassociated type exists in 8 strains (DSM 40233, D62, NBRC 13083, J1074, DSM 40455T, NBRC 100770, “S. wadayamensis” A23, and CR13) from clade I and all strains from clade II, the free-living type exists in the remaining 6 strains from clade I and all outgroup strains, and the entomic type exists in all strains from clade III. Differential genes between the genotypes are marked with yellow background.
