Phylogenetic analysis of Dpps.

Except for L. migratoria a136595 and O. furnacalis Unigene7326 (marked in red), the used amino acid sequences of other 33 Dpps are from mouse (Mm), zebrafish (Dr), lancet (Branchiostoma floridae; Bf), acorn worm (Ptychodera flava; Pf), the sea urchins Strongylocentrotus purpuratus (Sp) and Lytechinus variegatus (Lv), fruit fly (Dm), flour beetle (Tribolium castaneum; Tc), sawfly (Athalia rosae; Ar), buckeye butterfly (Junonia coenia; Jc), the grasshoppers Schistocerca americana (Sa) and S. gregaria (Sg), cricket (Gryllus bimaculatus; Gb), Cupiennius salei (Cs), Ceratitis capitata (Cc), Blattella germanica (Bg), Polyrhachis vicina (Pv), Episyrphus balteatus (Eb), Apis mellifera (Am), Pheidole morrisi (Pm), Biston betularia (Bb), Bombyx mori (Bm), Culex quinquefasciatus (Cq), Nasonia vitripennis (Nv). The branches specific for arthropod Dpps and TGF-beta homologs are shaded in blur and yellow, respectively. For explanation of the arrows see Fig. 6.
