Representative microarray clusters of genes with elevated expression in females or males. Genes with these expression profiles may be involved in pheromone production. A "male-enriched" cluster (A) includes CYP6CR1 (red curve) and has an expression pattern consistent with exo-brevicomin production. (B) Mevalonate gene expression. The putative GGPPS representative (contig126, blue curve) has an expression profile similar to those for HMGS and HMGR. Expression values are processed, normalized, and log2-transformed microarray data for whole juvenile stages or midguts and fat bodies of adults. FPPS, farnesyl diphosphate synthase; GGPPS, geranylgeranyl diphosphate synthase; HMGL, HMG-CoA lyase; HMGS, HMG-CoA-synthase; HMG-R, HMG-CoA-reductase; IPPI, isopentenyl diphosphate isomerase; MK, mevalonate kinase; PMDC, phosphomevalonate decarboxylase.
