Figure 1From: Trees on networks: resolving statistical patterns of phylogenetic similarities among interacting proteinsPhylogeny of study species. This shows the phylogenetic tree for the study species used in this paper. The evolutionary relationship is shown for the ten yeast species used [53, 54]. S. cerevisiae proteins resulting from gene duplication events are thought to retain the same interactions as the original gene for millions of years rather than tens or hundreds of million years [55].Back to article page
