A phylogenetic tree was built for Bacterial and Archaeal orders from the GEM catalogue and previously existing reference genomes. Green branches indicate new lineages represented only by the GEM catalogue. The inner strip chart indicates whether an order is newly identified (green; represented only by GEMs) or was previously known (light gray; represented by a reference genome). The next strip chart indicates if an order is uncultured (blue; represented only by metagenome-assembled genomes) or cultured (gray; represented by an isolate genome). The next four strip charts indicate the environmental distribution, while the bar plot indicates the number of genomes from the GEM catalogue recovered from each order. The GEM catalogue contains metagenome-assembled genomes that are broadly distributed across the tree of life and includes numerous new order-level clades. Vast regions of the tree are represented only by uncultivated genomes from the GEM catalogue and previous studies. (Stephen Nayfach)
