From: Proteomic characterization and evolutionary analyses of zona pellucida domain-containing proteins in the egg coat of the cephalochordate, Branchiostoma belcheri

Figure 7

The evolutionary relationships of ZP proteins from a jawed vertebrate ( O. latipes, Ol), a non-jawed vertebrate ( P . marinus, lamprey), cephalochordates ( B. belcheri and B . floridae, Bb and Bf), and a urochordate ( C. intestinalis, Ci ) deduced by Bayesian analyses. The tree is drawn to scale with branch lengths in identical units to those of the evolutionary distances used to infer the phylogenetic tree. The posterior probability is shown to the side of each branch. The different ZP protein clades in this figure that are described in the Results section are labeled under the bold letters: A,B, C and D respectively.
