Expression of T. castaneum sensory neuron membrane proteins (SNMPs). Heat map showing the expression level of the six sensory neuron membrane proteins of T. castaneum, as a log2[RPKM + 1] value in different tissues [adult antennae, head (missing antennae but including mouthparts), mouthparts, legs, body, as well as larval head and body]. The candidates are ordered according to their chromosomal localization (Additional file 9: Figure S5b). Horizontal brackets above indicate clustering in the genome, and the arrowheads represent the orientation of the open reading frame. 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- and the blue down-regulation (p values adjusted are * < 0.05, ** < 0.01, and *** < 0.001). SNMP sensory neuron membrane protein, RPKM reads per kilobase per million
