Phylogenetic tree showing relationship of R. leguminosarum bv trifolii CC275e with closely and distantly related taxa in the order Rhizobiales. The tree is based on 1498 bp length alignment of the 16S rRNA gene using MUSCLE with default parameters [31]. The tree was constructed using maximum likelihood method, with the General Time Reversible model (rate 4 classes; [32]). Nodes with bootstrap (1000 repetitions) support > 50 % are shown [33]. Accession numbers relating to the nucleotide sequences for each of the strains are listed in Additional file 1: Table S1
