Location of sampling sites and host of origin for strains of root-nodule bacteria isolated from the nodules of 8 Australian native legumes used in the glasshouse inoculation trials [see 37].

All strains are Bradyrhizobium spp., except those designated as phylotype Q which are Rhizobium spp. Those strains marked with ‘+’ represent the subset used in Expt II that were characterised as symbiotically effective on their own host species in Expt I.
