Additional Information
Statement
Reference

Avic\GFPGr5a.3x.IRES.2x labels the sugar-sensing neurons (S cell) of the taste bristles of the proboscis. Neurons labeled with Avic\GFPGr5a.3x.IRES.2x do not overlap with expression of Scer\GAL4ppk28.PC, which labels the water-sensing neurons.

Avic\GFPGr5a.3x.IRES.2x is expressed in a subset of sugar-responsive gustatory receptor neurons of the labellum that project to regions PMS4 and PMS5 of the posterior maxillary sensory center. The projections pattern overlaps with the one of Scer\GAL4NP1017.

Avic\GFPGr5a.3x.IRES.2x is expressed in the sugar-sensitive gustatory receptor neurons of the labellar taste pegs of the proboscis. Expression of Avic\GFPGr5a.3x.IRES.2x in the proboscis is distinct from the expression of Scer\GAL4E409. The projection of the neurons labeled by Avic\GFPGr5a.3x.IRES.2x in the anterior subesophageal ganglion does not overlap with the projections labeled by Scer\GAL4E409.
