Additional Information

Scer\GAL4ppk.PG drives expression strongly in class IV dendritic arborization neurons and weakly in class III neurons.

Drives expression strongly in class IV dendritic arborization neurons and weakly in class III neurons.

Scer\GAL4ppk.PG drives expression in larval multidendritic neurons (Type II). All of the Type II neurons identified by Scer\GAL4ppk.PG are also labeled with Scer\GAL4Piezo.1.0.

Scer\GAL4ppk.PG drives expression in all class IV dendritic arborizing neurons which co-express Ncra\QFTrpA1.PP.

Scer\GAL4ppk.PG drives expression in peripheral sensory neurons in the legs, wings, body wall, and reproductive tract. In the reproductive tract it is expressed in 2-3 fruitless expressing neurons on either side of the uterus as well as a small number of neurons surrounding the oviduct. The reproductive tract neurons project fine processes between the muscle and epithelial layers that enter and arborize within the lumen of the uterus while other processes bifurcate close to the soma and innervate the lower regions of the common oviduct, both these aborizations run along the inner surface of the epithelial cell layer. Infrequently, expression is also seen in 1-2 neurons near the base of the antennal nerve and the the lateral horn. Afferents from all of the above neurons contribute to the abdominal nerve trunk, most terminating in the thoracico-abdominal ganglion but some extend further in an anterior direction, and a pair of bilateral fibers emerge from the network in the abdominal ganglion, traverse the entire length of the ventral side of the nerve cord, extend through the cervical connective before terminating in the posterior region of the adult gnathal ganglion.

Scer\GAL4ppk.PG drives expression in the adult peripheral neurons, including 2 neurons on each lateral oviduct and 15 neurons on each side of the uterus, organised in 3 clusters.
