Phylogenetic tree (not rooted) based on rpoD (a) and gyrB (b) gene sequence showing position of 3 Pseudomonas isolates from Medicago sativa rhizosphere in relation to taxonomically similar bacteria. The analysis was conducted using the neighbor-joining test. The scale bar indicates 0.01 (a) and 0.02 (b) changes/site. Bootstraps of 1000 replicates were used and are shown at the branch nodes of the phylogenetic tree
