Reference

Drives expression in the prothoracic gland, but not in the corpus allatum.

(FlyBase Curators, 2017)

In the ring gland, ScerGAL4phm.PO is expressed in the prothoracic gland but not in the corpus allatum. Transient expression is also observed in the presumptive notum of the wing disc, and in a patch of the presumptive thorax of the leg discs in wandering third instar larvae.
