Phylogenetic tree for genes related to SRAP identified from L. foliolata (Vickery et al., 2001). The tree contains two groups 1) an echinoderm only group indicated by the purple rectangle that includes genes from all 5 extant classes of echinoderms. Another group of genes from Echinoderms that are sisters to genes from Chordates, Arthopods, Nematodes, and Cnidaria. Our phylogenetic results show that SRAP orthologs in echinoderms consist of genes that occur only in echinoderms and genes that are closely related to taxonomically distant organisms (e.g., Chordates, Arthropods, Nematodes and Cnidaria).
