Quantitative analysis of the antennal transcriptome in male and female C. hominivorax. (a) A total of 10,442 genes were expressed in the antennae, of which 85 were differentially expressed (DE) between sexes (FDR corrected p < 0.05). Thirty-four genes showed male-biased expression and 51 showed female biased expression. Of the 85 DE genes, 27 were chemosensory genes (16 ORs, 0 GRs, 3 IRs and 8 OBPs). (b) Multivariate analysis was used to explore sex-specific differences in 114 chemosensory genes expressed in the antennae. PC1 explained 49.5% of the variation and grouped the samples according to sex. (c) RT-qPCR validation of six olfactory receptor genes differentially expressed between male and female C. hominivorax antennae. Data is the average of the biological replicates, and error bars illustrate standard error of the mean (SEM). Expression levels of each of the six genes were significantly different (p < 0.05).
