Maximum likelihood trees based on datasets of marker genes as identified by ezTree. a The phylogram is based on a dataset of the most abundant bin from each fecal sample and Photobacterium reference genomes . The tree was rooted in the 2 Vibrio and Escherichia genomes. Bootstrap values are from a ML analysis (500 pseudoreplicates, JTT model). The cladogram shown in gray background is from Hilgarth et al.  and shows the established phylogenetic relationships between a wider range of Photobacterium species. The numbers in parentheses represent the number of species in each clade. b The phylogram is based on a dataset that includes MBRG-29_bin5 and MBRG-35_bin5 and reference genomes from the Aliivibrio genus. The cladogram is from Ast et al.
