Figure 1.

Phylogenetic tree of Neurotrophin/Spz genes: Spz family. The full Spz/neurotrophin(Nt) tree is shown on the left side, while on the right side, an enlarged view of the Spz family is depicted. BI phylogenetic tree is shown, but analyses with ML are also represented via bootstrap support values on the tree. BI pp (posterior probability) values figure directly above the branches while ML bootstrap values are directly below the branches.
