Fig. 3: Neighbor-Joining phylogenetic tree based on ribosomal 16S rRNA sequences obtained from metagenome-assembled genomes (MAGs), amplicon-sequence variants (ASVs) reported by Diaz-Garcia et al. [13], and isolated bacterial axenic cultures from the MELMC.

A copy of the 16S rRNA gene was randomly selected from each MAG to build the phylogenetic tree. Bootstrap tests (1000 replicates) are shown next to the branches and evolutionary distances are in units of the number of base differences per site. At right, we display the colonies of the recovered bacterial axenic cultures (Pseudomonas protegens and Bacillus subtilis).
