Third instar larvae expressing ppk19dsRNA.Scer\UAS under the control of Scer\GAL4VGlut-OK371 do not show defects in synaptic homeostasis in the presence of philanthotoxin-433.
Larvae expressing ppk19dsRNA.Scer\UAS under the control of Scer\GAL4elav.PLu show defective salt-taste behaviour.
Transcription from the P{UAS-ppk19.dsRNA} construct should produce ppk19 dsRNA, resulting in dsRNA interference (RNAi) of the ppk19 gene.
