FIGURE 4.

Bayesian phylogenetic analysis of kinin precursor. The phylogenetic tree was constructed in MrBayes with four chains and four runs of the mixed amino acid model for 1,000,000 generations with a 10% burnins. Node values are Bayesian posterior probability rounded to two significant figures. Scale refers to branch length and represents the probability of an amino acid substitution along that interval. The number of kinin paracopies encoded by each precursor is denoted in the parentheses. “^∗” Indicates there could be more kinin paracopies present in this species as the predicted amino acid sequence likely only encodes a fragment of the kinin precursor due to gaps present in the predicted transcripts in NCBI. The curated protein sequences and version numbers of corresponding transcript sequences are in Figure 3A.
