The GTDB taxonomy is based on genome trees inferred with <a
The GTDB taxonomy is based on genome trees inferred using <a
href="http://www.microbesonline.org/fasttree/" target="_blank">FastTree</a> from an aligned concatenated set of
120 single copy marker proteins for Bacteria, and with <a href="http://www.iqtree.org/">IQ-TREE</a> from a concatenated set of 53
(starting with R07-RS207) and 122 (prior to R07-RS207) marker proteins for Archaea (download page <NuxtLink to="/downloads">here</NuxtLink>).
Additional marker sets are also used to cross-validate tree topologies including concatenated ribosomal
proteins and ribosomal RNA genes. <a href="https://www.ncbi.nlm.nih.gov/taxonomy" target="_blank">NCBI taxonomy</a> was initially used to decorate the genome tree via
proteins and ribosomal RNA genes.

<a href="https://www.ncbi.nlm.nih.gov/taxonomy" target="_blank">NCBI taxonomy</a> was initially used to decorate the genome tree via
<a href="http://tax2tree.sourceforge.net/" target="_blank">tax2tree</a> and subsequently used as a reference source of new taxonomic opinions including new names.
The 16S rRNA-based <a href="http://greengenes.secondgenome.com" target="_blank">Greengenes</a> and <a href="https://www.arb-silva.de/" target="_blank">SILVA</a> taxonomies were intially used to supplement the taxonomy
particularly in regions of the tree with no cultured representatives, however genome assembly
identifiers are now used to create placeholder names for uncultured taxa. <a href="https://lpsn.dsmz.de/" target="_blank">LPSN</a> is used as the
primary nomenclatural reference for establishing naming priorities and nomenclature types. All t
axonomic ranks except species are normalised using <a href="https://github.com/dparks1134/PhyloRank" target="_blank">PhyloRank</a> and the taxonomy manually curated to
remove polyphyletic groups. Polyphyly and rank evenness can be visualised in PhyloRank <NuxtLink :to="latestStatsPageUrl">plots</NuxtLink>.
Delineation of species was initially done based on phylogeny and rank normalization but was
substituted with the ANI-based method (starting with R04-RS89) to enable scalable and automated assignment of genomes to species clusters.
