Fig. 2: Phylogeny and quality of reconstructed MGC-containing genomes.

The phylogenomic tree displays 41 non-redundant MGC-containing genomes alongside 33 previously published representative MTB genomes and 60 non-MTB genomes, based on 120 bacterial single-copy marker protein sequences. Note that the tree is built with approximate maximum likelihood (ML) approach and is intended to provide a general phylogenetic context for the identified MGC-containing genomes rather than definitive insights into the deep evolutionary history of magnetotaxis. The tree is surrounded by layers indicating, from innermost to outermost, the completeness, contamination, size, GC content, and taxonomy at the phylum and class levels for each genome. Branches of the 41 non-redundant MGC-containing genomes are colored in red and marked with red dots on the outer edge. Branches of the 33 previously published representative MTB genomes are colored in black and marked with black dots. The MGC-containing genome affiliated with the phylum Myxococcota is highlighted with a red triangle.
