Figure 2.

V-ATPase subunit expression abundance in various antennal transcriptomes. Expression of all genes detected in the Drosophila antennal datasets [58,59] is plotted, colored, and ordered low-to-high by its expression abundance. All known genes involved in proton transmembrane transport (including all V-ATPase subunits) are labeled, whereby labels are vertically displaced from where the gene appears. V-ATPase subunit expression is compared across fly sex (A) and between fly cohorts with intact or absent coeloconic sensilla constituent of the IR olfactory subsystem (B).
