Figure 1

Volcano plots illustrating microarray results. Shown are numbers of significantly (P <0.05) upregulated (blue; ≥1.19-fold) and downregulated (red; ≤0.84-fold) microarray positions from four treatments that included juvenile hormone (A), soldier head extract (B), live reproductives (C) and live soldiers (D). The fold ratios on the x-axis represent the ratio of EST abundance for each of the four treatments relative to untreated controls. The numbers of contigs formed from ESTs of host or symbiont origin are given in each panel.
