See Figures 2 to 7 for phylogenetic positions of all gene copies. Protein IDs, genomic coordinates and expression data for each gene copy is available in Additional File 2. Partial gene sequences and putative pseudogenes are not included below, but are discussed in the text and also provided in Additional File 2.
