AgOr Expression Profile. Left panel - expression profile map. Green color intensity scale (below map) indicates increasing RPKM values from left to right. (FP - female palps; FB - female bodies; FA - female antennae; MA - male antennae; MB - male bodies; MP - male palps). Middle panels - volcano plots showing the relative transcript expression of AgOrs in bodies versus antennae. Individual data points were plotted at the intersection of the log10 of Fisher's exact test (y-axis) and the log2 of the ratio of antennae (or palps) RPKM: bodies RPKM (x-axis) for each gene. Red diamonds or blue circles represent significantly enhanced AgOrs in antennae (top panel) or maxillary palps (bottom panel) of females and males, respectively. Gray points represent AgOrs that fell below the significance threshold of 3.9 × 10-6or the 2-fold differential expression cutoff. RPKM values of 0.00 were transformed to 0.10 prior to calculating RPKM ratios, such that those genes could also be represented on the plot. Right panels - Proportional Venn diagrams showing the number of AgOrs that are significantly enhanced in female and male antennae (top) and maxillary palps (bottom).
