Additional Information
Statement Reference Adult expression is observed in chemosensory neurons of about 10 male-specific gustatory bristles in the forelegs. (Bray and Amrein, 2003) Scer\GAL4[Gr68a.PB] drives expression in two gustatory receptor neurons of the larval ventral pharyngeal sense organ (VPS or hypophysis). (Kwon et al., 2011) Scer\GAL4[Gr68a.PB] drives expression in the gustatory neurons of a subset of gustatory sensilla in the prothoracic male legs. These same sensilla are also labeled by Scer\GAL4[CheB42a.PX] although expression is found in different cells of each sensilla. (Park et al., 2006)
