Figure 5.
Syntenic relationships of platypus and reptile venom peptides, based on previously published therian synteny (Patil et al. 2005; Belov et al. 2007) and our phylogenetic analysis (Fig. 2). This shows that the platypus OvDLPs and sauropsid reptile vCLPs and crotamines have evolved from different beta-defensin paralogs belonging to the ancestral synteny group A. Genome arrangements of reptile sequences are unknown, so these are inferred based on synteny and connected by dotted lines.
