Figure 4. Induced aphids have lower expression levels of genes associated with dopamine, serotonin, and octopamine synthesis and signaling pathways.

Figure 4

The expression levels of genes associated with the production and signaling of biogenic amines were clustered via GENE-E using average FPKM expression values for each of the four experiments. Clustering is by experiment and by gene using Pearson correlation coefficients. Expression values are relative to one another within each gene, with red the highest and blue the lowest. ♦ indicates genes that are significantly differentially expressed between the starved 16 hour time point and the fed 16+5 hour time point (16hr samples vs. 16+5hr samples) as well as between the crowded and solitary samples at the 16+5 hour time point (Cr16+5 Vs Sol16+5 samples). ○ indicates genes with significant differences in expression only between the starved 16 hour time point and the 16+5 hour time point comparison (16hr samples vs. 16+5hr samples).
