A Comparative Genomic and Phylogenetic Analysis of the Origin and Evolution of the CCN Gene Family

Figure 3

The establishment of the phylogenetic tree of CCNs. The phylogenetic tree was established by the neighbor-joining method with the alignment. Most of the homologs in the figure are described as “species name + gene name,” despite the exception that Ascidian CCNs are shown as “species name + gene symbol” to avoid gene name repetition. The brace on the right side sorts the homologs according to CCN family member individually. The bootstrap percentage was presented near the location where branches cluster together.
