# Database The mOTUs database is constructed by clustering universal single-copy phylogenetic marker genes from reference genomes, single cell-assembled genomes (SAGs), and metagenome-assembled genomes (MAGs). The latest database version (mOTUs 4.0) consists of a total of 124,295 mOTUs comprising: * 30,256 mOTUs containing at least one isolate genome * 94,039 mOTUs consisting of only MAGs You can access and query the latest version of the mOTUs database here. ![](images/logos_motus_website.png) elixir mOTUs is part of the ELIXIR-CH Service Delivery Plan.
