Flies expressing Or67bScer\UAS.T:Hsap\MYC under the control of Scer\GAL4Or22a.8197 in a Df(2L)dp-79b/Dp(2;2)dppd21 background (called Δhalo) show a large increase in electrophysiological response to either 2-ethylpyrazine or 2-methylpyrazine.
Df(2L)dp-79b, Dp(2;2)dppd21, Or67bUAS.Tag:MYC, Scer\GAL4Or22a.8010 has olfactory neuron & antennal sense organ phenotype
Expression of Or67bScer\UAS.T:Hsap\MYC in the 'empty neuron system' (in which Scer\GAL4Or22a.8010 is used as the driver and flies are homozygous for a synthetic deletion created by combining Df(2L)dp-79b and Dp(2;2)dppd21 on to the same chromosome) confers an odor response to the mutant ab3A neuron.
