Additional Information
Statement
Reference

In the third instar larva, ScerGAL4for.pr1 is expressed in a subset of neurons of the central brain, the brain lobes, and the ventral nerve cord; and in a few enteroendocrine cells of the anterior midgut. Expression is not observed in glia or in the fat bodies.
