Expressing spinScer\UAS.T:Disc\RFP under the control of Scer\GAL4ppk.PG results in third instar larval class IV abdominal dorsal multidendritic ddaC neurons exhibiting a significant decrease in the number of dendrite branch terminals, as compared to controls; expression under the control of Scer\GAL4221, in combination with Dicer-2 for efficient RNAi, results in no obvious dendrite morphology defects in class V abdominal dorsal multidendritic ddaD and ddaE neurons, as compared to controls.
