Additional Information
Statement
Reference

Drives expression in Or22a-expressing neurons that innervate antennal basiconic sensillum ab3 and project to antennal lobe glomerulus DM2.

(FlyBase Curators, 2017)

ScerGAL4Or22a.8197 drives expession in adult olfactory receptor neuron Or22 (ab3a neuron).

(Ronderos et al., 2014)

Adult expression is observed in the ab3 subclass of large basiconic sensillae.

(Tanoue et al., 2004)

Adult expression is observed in the ab3A neuron of the ab3 functional type of the large sensillum basiconicum in the dorsal medial region of antennal segment 3

(Hallem et al., 2004)

Adult expression is observed in the ab3A neuron of the ab3 functional type of the large sensillum basiconium in the dorsal medial region of antennal segment 3. These neurons project to antennal glomerulus DM2. More sensilla are labeled in female flies than in male flies.
