Table 3.

Sequences percentages of rhizobial and non-rhizobial species (top 40 abundant across all samples) associated with Sesbania cannabina (Sc), Glycine soja (Gs), and Glycine max (Gm) nodules. Since Ensifer and Sinorhizobium were synonymous genera, we used the name Ensifer to designate bacterial species in genus Sinorhizobium according to Young (2003) and Martens et al. (2008).
