Neighbour-joining phylogenetic tree for nodA gene sequences of nodulating strains isolated from Mimosa spp. with close relatives and type strains. Bootstrap values calculated for 1000 replications are indicated at the internodes. The scale bar indicates 5 % nucleotide substitutions per site. GenBank accession numbers are given in parentheses. Abbreviations: B., Burkholderia; C., Cupriavidus; E., Ensifer; R., Rhizobium; ^T, type strain. Strains with the prefixes MH, MHM and MP were isolated from M. hamata, M. himalayana and M. pudica, respectively. Strains isolated in the present study are marked in bold.
