Additional Information

Statement

Reference

Scer\GAL4^Ir76b.1.5 drives expression in gustatory neurons that do not detect sugar or express Gr64f in short labellar taste bristles S-c

(Asefa et al., 2024)

Scer\GAL4^Ir76b.1.5 drives expression in almost all labellar taste neurons.

(Asefa et al., 2024)

ScerGAL4^Ir76b.1.5 labels multiple cells of the labellum as well as axonal projections in the adult subesophageal zone. ScerGAL4^Ir76b.1.5 labelled cells have near complete overlap with expression driven by ScerGAL4^Ir76b.916.

(Ganguly et al., 2017)

Expression is observed in multiple gustatory receptor neurons per sensillum. In the tarsal sensilla, expression largely overlaps and includes sweet and bitter gustatory receptor neurons. Expression also occurs in multiple neurons per sensillum in the labial palps.

(Ahn et al., 2017)

Drives expression in almost all adult gustatory receptor neurons, and in a subset of multidendritic larval tracheal innervating neurons.
