FIGURE 2.
The majority of group II ORs are specifically expressed in sensilla basiconica. (A–D”) The Orco- and distinct OR-expressing cells were visualized by means of two-color FISH using specific antisense riboprobes labeled in Bio (green fluorescence) and DIG (red fluorescence), respectively. The four ORs (OR82, OR97, OR109, and OR113) are shown as representatives of group II ORs that are specifically expressed in sensilla basiconica. The white dash circle highlights the cell that concomitantly expresses a defined OR type and Orco. More examples are shown in the supporting data. Distinct OR cells are indicated by white arrows. Scale bars, 10 μm.
