<p>The networks were built using <i>gapA</i>, <i>gltA</i>, <i>gyrB</i>, <i>rpoD</i> genes. Strain legend is shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0131112#pone.0131112.t001" target="_blank">Table 1</a>. The scale bar indicates the number of substitutions per nucleotide position. Strong signal of recombination are present solely between the <i>Pseudomonas syringae</i> pathovars. <i>P</i>. <i>cannabina</i> pv. <i>alisalensis</i> Pcal BS91 was included in the analysis as outgroup.</p
