—ML tree based on concatenated sequences of the T3SS coding gene sequences ascF, ascG, and ascV (2,739 nt) reconstructed using a GTR model plus gamma distribution as a substitution model from 21 complete nucleotide sequences. The numbers at the nodes are support values estimated with 100 bootstrap replicates. Only bootstrap values ≥70 are indicated. The major phylogenetic group of each strain is indicated by colored ranges on strain labels. The type of genetic organization of the flanking genes shown in the inserted box is indicated for each strain with a numbered star. Abbreviation: WGS, whole-genome sequences.
