Expression of T. castaneum homologs of genes described to be involved in olfaction of D. melanogaster. Heat map showing the expression level of the several genes supposed to be involved in D. melanogaster olfaction, as a log2[RPKM + 1] value in different tissues [adult antennae, head (missing antennae but including mouthparts), mouthparts, legs, and body]. The expression levels are represented by a greyscale with highest shown expression levels labeled black. The asterisks mark statistically significantly differentially expressed genes compared to body (based on biological replicates of five antennal, two head, three mouthpart, two leg, and two body samples). The red asterisks represent up-regulation (p values adjusted are * < 0.05). RPKM reads per kilobase per million
