Figure 4From: A new haemocyanin in cuttlefish (Sepia officinalis) eggs: sequence analysis and relevance during ontogenyMaximum likelihood tree of the amino acid sequences of haemocyanin. The tree includes the haemocyanin sequences of Sepia officinalis isoform 1–3 (SoH1, SoH2, SoH3), Enteroctopus dofleini A-type (OdHA) and G-type (OdHG), Nautilus pompilius (NpH) and Haliotis tuberculata isoform 1 and 2 (HtH1, HtH2) calculated with PhyML using the LG + I + G model to illustrate the evolution of cephalopod haemocyanin. The tree topology of the Bayesian tree calculated with MrBayes using the WAG + I + G + F model is similar. Therefore, support for the tree nodes is given by the bootstrap values of 1,000 replicates and the consensus support (%).Back to article page
