Figure 5From: Identification, distribution and molecular evolution of the pacifastin gene family in MetazoaSimplified phylogenetic tree of the different classes and orders of Hexapoda and Crustacea. Orders, for which less than 3000 and 1000 nucleotide or EST sequences are deposited in Genbank, are marked by an * and **, respectively. The classes and orders, in which pacifastin-related members were identified, are highlighted.Back to article page
