Phylogenetic trees for expanded protein families in Lac. Abbreviation of the species and protein names are used as labels in the phylogenetic trees. We colored the labels to indicate which species the protein is from: Lac (purple), Pgl (dark yellow) Dpl (cyan), Hme (green), Mci (blue), Bmo (orange), Pxy (red) and Drosophila melanogaster (black). The clades corresponding to the unique gene expansion events in Lac are highlighted in light magenta. a Phylogenetic tree of endochitinases. b Phylogenetic tree of Geranylgeranyl pyrophosphate synthases. c Phylogenetic tree of Pheromone-binding proteins.
