Phylogeny, organization, and distribution of the muc-like BGCs. a The Maximum likelihood tree of nucleotide sequences covering mucA-E from the 63 muc-like BGCs. Strains belonging to the same species were plotted as one branch; see the detailed tree showing information of all strains in Additional file 1, Fig. S9. The four types of muc-like BGCs were represented by different colors. b Organization and distribution of the four types of muc-like BGCs. The hosts of strains are indicated by black icons and text on the right. Transposases or recombinases at the adjacent position are marked with red bars
