Additional Information
Statement
Reference

Drives expression in the neurons of sugar-sensitive long, intermediate, and short labellelar taste bristles.

(FlyBase Curators, 2017)

ScerGAL4Gr5a.8.5 drives expression in all sweet taste receptor neurons in the labellar taste hairs, and in about 9 segmental tarsal sugar-sensing chemosensory neurons in the prothoracic leg that project to the prothoracic ganglion.

(Thoma et al., 2016)

ScerGAL4Gr5a.8.5 drives expression in adult abdominal multidendritic neurons with with dorsal processes extending along the left-right axis, as well as in multidendritic neurons with lateral processes extending anteroposteriorly; these major processes have several protruding dendrites. Additionally, expression is driven in laterally localized multidendritic neurons with extensive arborization. Expression is also observed in projections to the abdominal ganglion.

(Park and Kwon, 2011)

ScerGAL4Gr5a.8.5 is expressed in the sugar-sensitive neuron of a subset of the short labellar taste bristles.

(Weiss et al., 2011)

ScerGAL4Gr5a.8.5 is strongly expressed in the sugar-sensitive neuron of all long, intermediate and short taste sensilla of the labellum.

(Weiss et al., 2011)

ScerGAL4Gr5a.8.5 is expressed in all the sugar-sensitive receptor neurons of the gustatory sensilla of the labellum.

(Weiss et al., 2011)

ScerGAL4Tre.8.5.cCa expresses in Tre (Gustatory receptor Gr5a) neurons.

(Yang et al., 2008)

ScerGAL4Tre.8.5.cCa expresses in approximately 30 neurons per labial palp, in one neuron in most sensilla.
