MDS representation of the distances among 264 strains of <i>X</i>. <i>arboricola</i> pv. <i>pruni</i>.

<p>Countries of origin are represented by different symbols. MDS axes 1–2, 1–3 and 1–4 described 59.3%, 47.4% and 44.4% of the total variation, respectively.</p

Categorical minimum spanning tree from MLVA data (239 strains and 119 haplotypes) representing the genetic diversity of the Spanish strains of <i>X</i>. <i>arboricola</i> pv. <i>pruni</i> in relation with its province of origin.

<p>Dot diameter represents the number of strains per haplotype. Numbers represent the 18 genetic clusters identified. Haplotypes in the same genetic cluster are up to quadruple locus variants. Thick links indicate single locus variants and thin links indicates double locus variants. Shaded areas show different clonal complexes in genetic clusters 1 and 2 and are identified with letters (A-E). Genetic clusters not enclosed in dashed lines are formed by a unique clonal complex or singleton. *Indicates the primary founder haplotype.</p

Genetic differentiation of Spanish strains of <i>X</i>. <i>arboricola</i> pv. <i>pruni</i> from seven provinces (n ≥ 12) estimated by F_ST (above the diagonal) and R_ST (below the diagonal) pairwise comparisons based on MLVA data.
