Phylogenetic tree highlighting the position of the Ralstonia solanacearum UY031 (shown in bold) relative to other strains from the same species. The phylogenetic tree was constructed using four conserved prokaryotic marker genes, namely: recA, rpoA, rpoB and rpoC. Each gene was aligned individually with MUSCLE [25]; the resulting multiple alignments were concatenated. PhyML [26] was used to perform tree reconstruction using the GTR model and 1,000 bootstrap replicas. Strain names are colour-coded according to the correspondent phylotype. GenBank accession numbers are displayed within brackets. Strains whose genome was completely sequenced are marked with an asterisk. Ralstonia pickettii 12 J (NCBI accession NC_010682) was used as an outgroup
