Phylogenetic tree of Ps strains based on concatenated partial sequences of the gltA, gyrB and rpoD genes by using the maximum likelihood method and Tamura–Nei model. Bootstrap values ≥ 50% (1000 replicates) are indicated at branch points. Bar scale, substitutions per site. This analysis involved 25 nucleotide sequences, with a total of 2092 positions. Analyses were conducted in MEGA11 [60]. P. syringae pv. actinidiae CFBP 7811, P. syringae pv. actinidifoliorum CFBP 8161, P. syringae pv. tomato CFBP 2212, P. avellanae NCPPB 4222 and P. syringae pv. antirrhini strain 126 were included as controls and P. asturiensis 221^T as outgroup. Accession numbers of the sequences are shown in Supplementary Table S1.
