Pairwise comparisons of gene expression in venom glands (A), teratocytes (B) or larvae (C) relative to ovaries. Loci classified as differentially expressed in venom glands (red), teratocytes (blue) or larvae (green) are indicated in the upper left of each graph while loci classified as similarly expressed in both the query and ovaries are indicated in the upper right (light grey). All other loci are indicated as dark grey. Overlap between (D) loci differentially expressed between venom glands, teratocytes, and larvae, (E) loci similarly expressed between venom glands, teratocytes and larvae, and (F) differentially expressed loci whose corresponding proteins were detected in venom gland and teratocyte secretions. Colouration in D-E is the same as in A-C. Two loci from venom glands, a plancitoxin (a deoxyribonuclease) and an uncharacterized member of the conotoxin superfamily, met the criteria (see results) for both the differential and similar expression categories (Shiomi et al. 2004).
