Figure 2From: Characterization of the first beta-class carbonic anhydrase from an arthropod (Drosophila melanogaster) and phylogenetic analysis of beta-class carbonic anhydrases in invertebratesMinimum-evolution tree of 26 invertebrate β-CA sequences. Bootstrap consensus tree of 1,000 replicates. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test are shown next to the branches. See Table 1 for identification of species.Back to article page
