Figure 3. Frankia phylogeny, based on dnaA, ftsZ, and pgk genes, computed by maximum likelihood, following a GTR + I model of evolution, and tested by 1,000 bootstrap replicates. Sequences of Frankia isolated from Georgia are highlighted according to region as shown in Fig. 1.

Sequences are named according to their sampling sites, and reference sequences are named as in Pozzi et al. (2015).
