Figure 2.

Phylogenetic distribution of genome sequencing projects. Archaea and Bacteria are shown to the phylum level and Eukarya to their first taxonomic branching, with the exception of Metazoa and Fungi. The numbers in parentheses represent the number of completed, published (red) and ongoing (blue) genome projects. The tree is based on the taxonomy database from the National Center for Biotechnology Information (NCBI). Information about ongoing genome projects has been obtained from the Genomes OnLine Database (GOLD) [14], as of 22 January 2003.
