Phylogenetic tree highlighting the position of Chryseobacterium bovis relative to type species within the genus Chryseobacterium. Maximum likelihood (ML) tree inferred under the GTR + CAT model and rooted with Elizabethkingia. The branches are scaled in terms of the expected number of substitutions per site. The numbers above the branches are support values when larger than 60% from ML (left) and maximum parsimony (MP, right) bootstrapping. Phylogenies were inferred by the GGDC web server [34] available at (http://ggdc.dsmz.de) using the DSMZ phylogenomics pipeline [35] adapted to single genes. A multiple sequence alignment was created with MUSCLE [36]. ML and MP trees were inferred from the alignment with RAxML [37] and TNT [38], respectively. For ML, rapid bootstrapping in conjunction with the autoMRE bootstopping criterion [39] and subsequent search for the best tree was used; for MP, 1000 bootstrapping replicates were used in conjunction with tree-bisection-and-reconnection branch swapping and ten random sequence addition replicates
