Phylogenetic relationships of OR proteins from C. capitata, Z. cucurbitae, and D. melanogaster. The unrooted maximum-likelihood (log likelihood = −76938.28) tree was inferred using the LG model72 with gamma-distributed rates across site (+G) and + F option (LG + G + F). Bootstrap values greater than 50% (1000 replicates) are shown. The suffix –PSE after the protein name stands for pseudogene. For Drosophila, we have indicated the identity of the ORNs where OR genes are expressed and the chemicals among those tested in the current study that activate the ORs (consensual-scaled response above 0.56). Z. cucurbitae (Bcuc) sequences are in blue, C. capitata (Ccap) are in red, and D. melanogaster (Dm) are in black. The grey area shows the largest D. melanogaster gene cluster, the red area shows the largest tephritid gene cluster, and blue areas highlight the 1:1:1 orthologous sequences between the three species, or the 2:1:1 orthology when two duplicated D. melanogaster genes are expressed in the same ORN.
