No synaptic morphological defects are observed in the VA1v ORNs in adult flies expressing Srpk79DScer\UAS.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4peb-GAL4 and these flies do not display any defects in the olfactory attraction behavior toward attractive odorant (apple cider vinegar) in a trap assay.
Overexpression of Scer\GAL4elav-C155-driven srpk79DScer\UAS.T:Avic\GFP-YFP.Venus impairs synapse function in larvae. Excitatory postsynaptic potential amplitude is decreased in the mutants compared to wild-type larvae. Compared to wild-type larvae, there is a trend toward an increase in the average amplitude of spontaneous miniature events and the quantal content is perturbed in the mutants.
Srpk79DUAS.Venus, Scer\GAL4peb-GAL4 is a suppressor | partially of abnormal smell perception | adult stage phenotype of Lrp4GD14320, Scer\GAL4peb-GAL4
The loss of olfactory attraction behavior in response to an attractive odorant (apple cider vinegar) in adult flies expressing Lrp4GD14320 under the control of Scer\GAL4peb-GAL4 is ameliorated by co-expression of Srpk79DScer\UAS.T:Avic\GFP-YFP.Venus.
