From: Comparative genomic analyses reveal broad diversity in botulinum-toxin-producing Clostridia
Phylogenies of Clostridia strains inferred on (a) concatenated marker genes and (b) a SNP matrix. Phylogenies inferred with FastTree2 [54] on (a) 40 concatenated marker genes for the delineation of species (specI) [56] aligned with MUSCLE [57] and (b) a SNP-matrix including SNPs identified in at least 50 % of the analyzed strains produced by kSNP v2 [59]. The trees are rooted with Acetobacter woodii DSM 1030 [GenBank:NC_016894]. Strains are color-coded by botulinum neurotoxin serotype. Groups I-VI, Clostridium perfringens and C. tetani clades are labeled. Gray circles indicate bootstrap values over 90 %
