Figure 3. Visualization of fru P1 ∩ DIP neurons.

Maximum intensity projections of brain and ventral nerve cord tissues from 4- to 7-days old male and female flies. The fru P1 ∩ DIP intersecting neurons are labeled with green (rabbit α-GFP Alexa Flour 488), and neuropil are labeled with magenta (mouse α-nc82, Alexa Flour 633). The genotype is DIP-Gal4/10xUAS > stop > GFP.Myr; fru P1FLP, except for DIP-ι. This Gal4 transgenic strains was generated using a CRISPR-mediated insertion of the T2A-Gal4 with the dominant 3xP3-GFP marker. For this strain, 10xUAS > stop > myr::smGdP-cMyc was used and fru P1 ∩ DIP intersecting neurons are labeled with red (rabbit α-Myc, Alexa Flour 568) and then false-colored to green. The neuropil are labeled with magenta (mouse α-nc82, Alexa Flour 633). One Gal4 did not show consistent expression upon intersecting: DIP-iota. DIP-iota was tested with 10xUAS-RFP, and showed expression outside of fru P1 neurons.
