Neurons expressing IR52c and IR52a-GAL4 are distinct from neurons expressing markers of bitter or sugar neurons.
(A-F) IR52c is not expressed in bitter or sugar neurons. In male forelegs, neurons labeled by anti-IR52c antibody (magenta, A, C, D, F) in dorsally-oriented taste sensilla are distinct from neurons in ventral sensilla expressing Gr33a-GAL4 (green, B, C) and Gr64f-GAL4 (green, E, F). Scale bar represents 10 μm in A-F.
(G, H) Comparison of axonal projections of foreleg taste neurons expressing IR52a-GAL4 (green) with bitter neurons expressing Gr33a-GAL4 (magenta, G), and sugar neurons expressing Gr64f-GAL4 (magenta, H). Scale bar represents 10 μm in G, H. See also Figure S3.
