Sex-biased expression of ORs in C. hominivorax antennae. (a) Fifty-five ORs were expressed in the antennae, of which16 were differentially expressed between males and females, 8 each in females and males. Differential expression based on FDR adjusted p < 0.05. (b) Nine C. hominivorax ORs are closely related to D. melanogaster ORs based on the estimated OR phylogeny. Figures were generated using the interactive Tree of Life (iTOL) v4 software36 (https://itol.embl.de/). (c) Five male-biased ORs are closely related to the cis-vaccenyl acetate (cVA) pheromone receptor (Or67d) in D. melanogaster34,35, while one (Or63) is closely related to Or85f, which has been implicated in avoidance of the parasitoid volatiles actinidine and nepetalactol37. Two of the female-biased ORs are closely related to the 9-tricosene (Or7a), and methyl laurate, methyl myristate and methyl palmitate (Or88a) receptors in D. melanogaster38,39, all of which are implicated as fly pheromones.
