Representative whole mount in situ hybridisation (WMISH) expression profiles for a selection of 2DBD-NRs, NRs, GPCRs and ovipostatin differentially expressed between early veliger stage and adult reproductive organs (paired albumen and prostate glands). The expression patterns of these receptors and ovipostatin in early-veliger-stage larvae are broad, and generally similar; all genes are robustly expressed in ectodermal cells covering the foot (black arrowheads), surrounding the stomodaeum (white asterisk), the mantle (white arrowhead) and the cephalic lobes (yellow arrowheads). In adult tissues ovipostatin is highly expressed in the prostate and effectively undetectable in the albumen gland as expected. Qualitative differences are also evident for many of the receptors surveyed, and hint at possible roles in maintaining these simultaneously active reproductive organs. Representative scale bars are 100 mm.
