Statement
Reference

Scer\GAL4Gr23a.3.5 drives expression in a single pair of L2 GRNs in the adult labral sense organ that are maintained during the transition from larva (where they are known as gustatory receptor neurons of the epiphysis) to adult. These neurons send axonal projections in an umbrella like pattern to the left and right dorsal regions of the subesophageal zone and co-express (in separate experiments) Scer\GAL4Gr2a.2.2, Scer\GAL4Gr57a.6, and Scer\GAL4Gr93d.2.4.

Scer\GAL4Gr23a.3.5 drives expression in larval gustatory receptor neuron of the epiphysis DP3 where it is coexpressed with Scer\GAL4Gr2a.2.2, Scer\GAL4Gr57a.6, and Scer\GAL4Gr93d.2.4.

Scer\GAL4Gr23a.3.5 drives expression in one gustatory receptor neuron of the larval dorsal pharyngeal sense organ (DPS or epiphysis).
