Phenotype Manifest In

Detailed Description

Statement

Reference

Third instar larvae expressing ppk16^GD12781 under the control of Scer\GAL4^VGlut-OK371 show no significant increase in quantal content at the neuromuscular junction in the presence of the glutamate receptor antagonist philanthotoxin-433 (10μM), indicating a defect in synaptic homeostasis. In the absence of philanthotoxin-433, the larvae show no significant change in evoked excitatory postsynaptic potential (EPSP) amplitude or quantal content, and a small decrease in miniature mEPSP amplitude compared to controls.

Third instar larvae expressing ppk16^GD12781 under the control of Scer\GAL4^Mhc.PW do not show defects in synaptic homeostasis in the presence of philanthotoxin-433.

(Younger et al., 2013)

Adults expressing ppk16^GD12781 under the control of Scer\GAL4^elav.PLu (in the presence of Dcr-2^Scer\UAS.cDa to increase the efficiency of RNAi) can show significantly reduced avoidance of noxious temperature (46[o]C) compared to control flies, depending on the particular P{GD12781} insertion line used.
