UASt regulatory sequences drive expression of full-length Or42b coding sequences.
abnormal chemosensory behavior, with Scer\GAL4Orco.2.642.Hsim\VP22
Expression of Or42bScer\UAS.cGMa in all 21 olfactory sensory neurons, under the control of Scer\GAL4Orco.2.642.T:Hsim\VP22,display a level of weathervane correction stronger than individuals with bilateral olfactory function and wild-type larvae.
