The number of shared OTUs and sequences across different samples at a 3% genetic distance generated using a shared OTU table.

Samples compared	OTUs shared	Shared sequences
N+ rhizosphere	356	37,929
N− rhizosphere	221	37,541
N+ nodule	96	39,763
N− nodule	103	38,045
Bradyrhizobium elkanii H255	68	37,149
Rhizobium multihospitium-like HT221	64	31,514
Burkholderia pyrrocinia–like H022238	69	33,158
No inoculation	80	36,505
All samples	28	125,564

Data were obtained via analyzing the mean OTU value of two replicates of each treatment.
