Additional Information
Statement
Reference

Ir7a reporter is expressed in gustatory receptor neurons in 11 sensilla, all of which also label with Gr66a reporter. Ir7a is also expressed in two neurons in the prothoracic tarsi and in one neuron in the pharynx.

(Rimal et al., 2019)

ScerGAL4Ir7a.PC drives expression in 11 neurons in the adult labellum and in 2 neurons in the larval terminal organ. All of the labelled adult and larval neurons, except for one in the terminal organ, also express Ir25a.
