Additional Information
Statement
Reference

Drives expression in the sugar-responsive neuron of all of the short, intermediate and long taste sensilla of the labellum.

(FlyBase Curators, 2017)

ScerGAL4Gr64f.9.7 drives expression in sweet taste receptor neurons in the labellar taste hairs, and in about 12 sugar-sensing chemosensory neurons in the prothoracic leg. A subset of the leg neurons project to the ventral nerve cord then ascend through the cervical connective to the posterior gnathal gangion; these neurons, unlike the other ScerGAL4Gr64f.9.7-expression neurons, do not coexpress ScerGAL4Gr5a.8.5 or EcollexAVP16.Gr5a.cGa

(Thoma et al., 2016)

All labellar and many of the tarsal S cells expressing ScerGAL4Gr64f.9.7 send projections to the adult subesophageal zone.

(Fujii et al., 2015)

ScerGAL4Gr64f.9.7 is strongly expressed in the sugar-responsive neuron of all of the short, intermediate and long taste sensilla of the labellum.

(Weiss et al., 2011)

ScerGAL4Gr64f.9.7 is expressed in all the sugar-sensitive receptor neurons of the gustatory sensilla of the labellum.
