ScerGAL4amos.PZ drives expression in a subset of olfactory sensory organ precursor cells located in the presumptive third antennal segment of the antennal disc starting at 4 hours APF; these precursors go on to become basiconic and trichoid sensilla.
ScerGAL4amos.PZ-expressing neurons arrive at the antennal lobes at 28 hours APF.
Ablation of amos-positive olfactory receptor neurons by expressing Rcom\RAUAS.FRT under the control of Scer\GAL4amos.PZ together with Scer\FLP1ey.PN leads to the disorganization of the anterior antennal lobe and fuzzy glomerular borders, without affecting the formation of posterior glomeruli.
