Figure 3.

Phylogeny of the Rlc based on 120 core genes. The tree is rooted using R. anhuiense as the outgroup. The 18 potential genospecies are indicated by colored segments. Inner circles and symbols indicate variation in the sequence of the 16S rRNA gene (see text for details). The outer circle indicates the symbiovar inferred from the sequence of Nod genes (if any are present in the assembly). Black dots indicate branches with 100% bootstrap support. The representative strain for each genospecies is highlighted in white. An interactive version is available at https://itol.embl.de/shared/rhizobium.
