Additional Information
Statement
Reference

ScerGAL4Gr33a-GAL4 drives expression in bitter-sensing neurons in the larval dorsal pharyngeal organ.

(Rass et al., 2019)

Drives expression in bitter-activated gustatory receptor neurons in the adult labellum and in the tarsal segments of legs.

(FlyBase Curators, 2017)

ScerGAL4Gr33a-GAL4 drives expression in S-a and S-b bitter-activated gustatory receptor neurons in the adult labellum.

(Sung et al., 2017)

ScerGAL4Gr33a-GAL4 drives expression in L-canavanine-insensitive S2- and I-type sensilla.

(Shim et al., 2015)

ScerGAL4Gr33a-GAL4 drives expression in all I-type and S-type sensilla, which represent a total of 22 gustatory receptor neurons in each labellum.

(Poudel et al., 2015)

ScerGAL4Gr33a-GAL4 drives expression in two of the three gustatory receptor neurons innervating the dorsolateral terminal organ. These neurons coexpress ppk23, but not ScerGAL4GMR58F10

(Mast et al., 2014)

ScerGAL4Gr33a-GAL4 drives expression in about 20 gustatory receptor neurons (GRNs) in the adult labellum; these GRNs coexpress Gr66a. ScerGAL4Gr33a-GAL4 also drives expression in multiple gustory receptor neurons in the tarsal segments of the legs; these include 7 in each prothoracic leg, 4 in each mesothoracic leg, and 4 in each methoracic leg. Several of the prothoracic GRNs coexpress ScerGAL4Gr32a.3.776.
