AgIr Expression Profile. Left panel - expression profile map. Green color intensity scale (below map) indicates increasing RPKM values from left to right. Column labels same as Figure 5. Middle panels - volcano plots showing the relative transcript abundance of AgIrs in bodies versus antennae. Individual data points were plotted at the intersection of the log10 of Fisher's Exact test (y-axis) with 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 AgIrs in antennae (top panel) or maxillary palps (bottom panel) of females and males, respectively. Gray points represent AgIrs that fell below the significance threshold of 3.9 × 10-6 or the 2-fold differential expression cutoff. RPKM values of 0.00 were transformed to 0.10 prior to calculating transcript abundance ratios, such that those genes could also be represented on the plot. Right panels - Proportional Venn diagrams showing the number of AgIrs that are significantly enhanced in female and male antennae (top) or palps (bottom).
