The Genome Taxonomy Database (GTDB) is an online database that maintains information on a proposed nomenclature of prokaryotes, following a phylogenomic approach based on a set of conserved single-copy proteins. In addition to resolving paraphyletic groups, this method also reassigns taxonomic ranks algorithmically, updating names in both cases.[1] Information for archaea was added in 2020,[2] along with a species classification based on average nucleotide identity.[3] Each update incorporates new genomes as well as automated and manual curation of the taxonomy.[4]
An open-source tool called GTDB-Tk is available to classify draft genomes into the GTDB hierarchy.[5] The GTDB system, via GTDB-Tk, has been used to catalogue not-yet-named bacteria in the human gut microbiome and other metagenomic sources.[6][7]
The GTDB is incorporated into the Bergey's Manual of Systematics of Archaea and Bacteria in 2019 as its phylogenomic resource.[8]
