Upcoming Ensembl Platform Transition

This is the final release of its kind on this website.

In summer 2026, this site will bring you to the new Ensembl platform currently at beta.ensembl.org.
Please bookmark this archive to retain access to the current site, tools and functionality until they are available on the new platform -> eg63-protists.ensembl.org

Pan-taxonomic compara

The pan-taxonomic compara is built using representative genomes from all significant clades represented in Ensembl and Ensembl Genomes, to offer a broad view of homologous relationships from across the taxonomy. This analysis enables the production of protein trees and orthologies across all the taxonomic groups in Ensembl and Ensembl Genomes.

Species in the pan-taxonomic compara

Model genomes along with genomes not represented by the familes of model organisms are picked for this analysis.

The bacterial genomes included are selected on the following criteria:

  1. Presence in earlier versions of the pan-taxonomic compara
  2. Presence in the UniProtKB reference proteome list
  3. Europe PubMed Central citation count of over 1000

Data Access

The gene trees obtained from this analysis can be accessed in the genome browser and also using the Perl API and REST API. Note that when using the APIs, the pan-taxonomic comparative genomics data resource can be picked using the name "pan_homology".
