Additional Information
Statement
Reference

Drives expression in sugar-sensing neurons of the larval dorsal, posterior, and ventral pharyngeal sense organs; and in sugar-sensing neurons of a small number of taste bristles in the tarsus.

(FlyBase Curators, 2017)

ScerGAL4Gr43a-GAL4 drives expression in around four cells of the larval pharyngeal sense organ projecting to the embryonic/larval subesophageal ganglion.

(Mishra et al., 2013)

ScerGAL4Gr43a-GAL4 drives strong expression in two S cells in the middle segment of the prothoracic tarsal segment 5 and weak expression in two S cells at the tip of this segment. A total of 4 neurons are labelled in the adult proventriculus, 2 extend axons to the subesophageal ganglion and 2 to muscles of the mid gut, all 4 extend dentrites in the foregut lumen.
