Fig. 1: Phylogenetic tree of Xanthomonas perforans based on genetic distance of core gene SNPs, corrected for recombination.

Clades are highlighted by their respective core gene cluster, as determined by Rhierbaps (A). Core gene cluster identity is denoted by highlights overlaid on clades. Association with the tomato production system variables farm, transplant facility, and region, for the plant each strain was isolated from, are indicated by different colored blocks within each respective ring surrounding the phylogenetic tree. Reference genomes from three previously reported Florida X. perforans strains are denoted with bold text and black arrows. The number of categories within each variable was summed for each of the six clusters (B).
