Drives expression in bitter-sensing neurons.

Scer\GAL4Gr66a.1.8 drives expression in the following series of neurons. Larval gustatory receptor neuron of the epiphysis DP1, where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr93a.5, Scer\GAL4Gr22b.5.8, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr9a.6.3, Scer\GAL4Gr22d.3.1, Scer\GAL4Gr22e.2.5, Scer\GAL4Gr28b.a.3, Scer\GAL4Gr39a.b.1, Scer\GAL4Gr58b.1, and Scer\GAL4Gr59d.4.1. Larval gustatory receptor neuron of the epiphysis DP2 where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr77a.4 and Scer\GAL4Gr93b.5.3. Larval gustatory receptor neuron of the hypophysis VP1 and VP2 where it is coexpressed with Scer\GAL4Gr33a.4.7 and Scer\GAL4Gr68a.PB. Larval gustatory receptor neuron of the hypopharyngeal organ PP1 and PP2 where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr22b.5.8, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr39a.d.1.7, Scer\GAL4Gr93c.3.8 and Scer\GAL4Gr93d.2.4 Larval gustatory receptor neuron of the hypopharyngeal organ PP3 where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr28a.PT, Scer\GAL4Gr22b.5.8, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr39a.d.1.7, Scer\GAL4Gr93c.3.8 and Scer\GAL4Gr93d.2.4. Larval gustatory receptor neuron of the hypopharyngeal organ PP4 where it is coexpressed with Scer\GAL4Gr33a.4.7, Scer\GAL4Gr28a.PT, Scer\GAL4Gr22b.5.8, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39b.4.4, Scer\GAL4Gr39a.d.1.7, Scer\GAL4Gr93c.3.8 and Scer\GAL4Gr93d.2.4.

Scer\GAL4Gr66a.1.8 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.

Scer\GAL4Gr66a.1.8 is expressed in gustatory neurons of the bitter-sensitive short labellar taste bristles, and in gustatory neurons of all of the intermediate labellar taste bristles.

Scer\GAL4Gr66a.1.8 is strongly expressed in almost all of the short and intermediate taste sensilla of the labellum.

Scer\GAL4Gr66a.1.8 drives expression in 6 gustatory receptor neurons of the larval terminal organ, two of these having its cell body in the dorsal organ ganglion (TO-dorsolateral group). All 6 neurons co-express Scer\GAL4Gr33a.4.7. One of the neurons of the TO-dorsolateral group also expresses Scer\GAL4Gr10a.3.7 and Scer\GAL4Gr32a.3.7.PW. The other terminal organ neurons express different combinations of drivers. The first neuron expresses Scer\GAL4Gr32a.3.7.PW, Scer\GAL4Gr28b.e.4.245, Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr39a.b.1, Scer\GAL4Gr59d.4.1, Scer\GAL4Gr9a.6.3, Scer\GAL4Gr22e.2.5, Scer\GAL4Gr22a.4.2, Scer\GAL4Gr28b.a.3, Scer\GAL4Gr36b.0.9, Scer\GAL4Gr36c.2.5, Scer\GAL4Gr58b.1, Scer\GAL4Gr59a.1.5, Scer\GAL4Gr59c.5.5 and Scer\GAL4Gr93b.5.3. The second neuron co-expresses Scer\GAL4Gr39a.a.3.4, Scer\GAL4Gr57a.6, Scer\GAL4Gr59d.4.1, Scer\GAL4Gr47b.2 and Scer\GAL4Gr94a.3.7. The third neuron co-expresses Scer\GAL4Gr57a.6 and Scer\GAL4Gr97a.1. The fourth neuron expresses Scer\GAL4Gr39a.b.1 and Scer\GAL4Gr59d.4.1. Expression of Scer\GAL4Gr66a.1.8 is also found in two neurons of the dorsal pharyngeal sense organ (DPS or epiphysis), two neurons of the posterior pharyngeal sense organ (PPS or hypopharyngeal sense organ) and in two neurons of the ventral pharyngeal sense organ (VPS or hypophysis).
