Theory of prokaryotic genome evolution
Webb10 apr. 2024 · eukaryotes are labeled and colored by species name or species group. Above is a species tree of eukaryotes whose genomes were queried in this study. Species with branches colored gray lack detectable IRBP homologs in their genomes. The e-values of the 10 closest bacterial homologs to IRBP are shown to the left.
