Additional file 4: of The making of a pest: Insights from the evolution of chemosensory receptor families in a pestiferous and invasive fly, Drosophila suzukii

Or phylogenetic tree file (Nexus). Phylogenetic analysis of Ors in Drosophila suzukii (Dsuz), D. biarmipes (Dbia), D. takahashii (Dtak) and D. melanogaster (Dmel) using a Maximum Likelihood method. Evolutionary history was inferred using a Maximum Likelihood method based on the JTT matrix-based model. The tree was constructed using RAxML under the JTT model of substitution with NNI topology search, based on an amino acid alignment by MUSCLE. Branch support was estimated using 500 bootstrap replications. The tree is rooted with Orco. (NEX 26Â kb)
