The phylogenetic tree reconstructed from the protein distributions in the LD space using M
= 10 in (3
) in Materials and Methods. Eukaryotes are in red, prokaryotes (bacteria and Archaea) in blue and giruses in pink branches. MEGA5 [69
] was used to plot the trees. Because this tree is based on normalized protein densities (of 100 blocks in the M
= 10 tree here), the branch length of the tree is relatively small with a scale bar of 0.015.
