Figure 5.

Topography of cells expressing subfamily I‐A OBPs and olfactory receptor co‐receptor (Orco). (A–C) Merged images of fluorescence in situ hybridization on sections through the labial (A) and maxillary (B, C) palps of Schistocerca gregaria using digoxigenin and biotin‐labelled riboprobes of subfamily I‐A odorant‐binding proteins (OBPs) and Orco. Stained cells are either shown in red (Orco) or green fluorescence (OBPs). A close‐up of labelled OBP‐positive cells (green) and Orco‐expressing cells (red) is shown. The white dashed line indicates the boundary to the cuticle. (A–C, A–C) Single fluorescence channel images; either the green or the red fluorescence are shown. Scale bars: 20 µm.
