A 4665bp fragment of Or65a promoter sequence from upstream of the predicted start site is fused upstream of sequence encoding a GAL4 driver.
A 4665bp fragment of Or65a promoter sequence (starting at -2bp relative to the predicted start codon) is fused upstream of GAL4.
ScerGAL4Or65a.4.7 is expressed in the olfactory receptor neurons of a band of trichoid sensilla that extends along across the distolateral region of the antenna, and extends axons into the antennal lobe to arborize with antennal lobe glomerulus DL3.
