From: Gal4 drivers of the geosmin receptor Or56a exhibit ectopic expression in the labral sense organ of Drosophila

Fig. 1

Existing Or56a-Gal4 drivers exhibit expression in the labral sense organ (LSO). (a) A schematic of the Drosophila proboscis. The green dots indicate LSO sensilla 7, which contains eight chemosensory neurons (L7-1–8) on each side of the pharynx. L7-1–2 express Gr64f, L7-4–5 express ppk28, and L7-7 expresses Ir60b (see text for details). The red dotted rectangle indicates the approximate area shown in panels (b–d). (b–d) All three existing Or56a-Gal4s exhibit expression in the LSO. Green color represents GFP expression driven by the indicated Gal4 drivers, and magenta color represents cuticular autofluorescence. Scale bar = 20 µm.
