Phylogenetic tree of 87 assembled Shark Bay smooth mat microbial metagenome-assembled genomes (MAGs). MAGs assigned to different phyla are highlighted in color, and the estimated completeness of each draft genome is represented by pie charts. SM_103, 152, 180, 194, 225, and 277 were excluded from the tree as coherent taxonomic classification could not be generated from these MAGs using Phylosift (color figure online)
