Figure 3

(a,b) Expression patterns of Gr5a-GAL4 (a) and Gr64f-GAL4 (b). (c–e) Double labelling of Gr64f-GAL4 with UAS-mCD8::RFP (red) and Gr5a-LexA with LexAop-mCD8::GFP (green) in the GNG (c), pro-, meso-, metathoracic ganglia (PN, MN and MtN) and abdominal centre (AC) of the VNC (d) and fifth tarsal segment of the foreleg (e). Expression in the GNG and VNC is widely overlapping (yellow). Note non-overlapping expression in atGRNs (arrowheads in c and e; red) and projections from the wings (arrow in d; green). (f,g) Single GRN flp-outs in the VNC (f) and GNG (g) (red). Note the distinct projections from a stGRN (f, arrow) and an atGRN (f,g arrowheads). Synapsin (ubiquitous synaptic marker) staining shown in blue. Partial projections, scale bars, 20 μm (e) or 40 μm (a–d,f,g).
