Phylogenetic trees. a Phylogenetic tree in the genus of Xanthomonas using MLSA. Nucleotide sequence of four concatenated housekeeping genes (DnaK, gyrB, GroEL and RecA) was extracted from the draft or complete genomes. The tree was constructed by applying all the concatenated sequences into Geneious software Version 6 with the Tamura-Nei genetic distance model and the Neighbor-joining method, with Stenotrophomonas maltophilia K279a as an outgroup. The scale bar indicates number of nucleotide substitutions per site. The dark red represents undulosa pathovars, the green color indicates the translucens pathovar and the yellow color represents the cerealis pathovars; b Phylogenetic tree of X. translucens strains using whole-genome discovery of SNP. The scale bar indicates number of nucleotide substitutions per site. Details are described in Methods
