acj6-GAL4AD, unc-4-GAL4DBD-driven myr-GFP marks 23B neurons throughout development.

(A, B) Acj6 (blue) and Unc-4 (magenta) co-expression shows robust overlap in GFP-marked embryonic progeny of NB7-4, 23B neurons, in a late-stage embryo. (C–D) Acj6 (blue) expression marks 23B neurons in an early stage larval VNC (C) and an early stage pupal VNC (D). The only lineages that express Acj6 are 23B, 8B, and 9B, and of these only the posterior-dorsal cells, corresponding to hemilineage 23B, co-stained for GFP and Acj6 in the larval and pupal VNC. (E) This driver combination marks a cluster of SEZ neurons (arrowhead) in the adult brain, presumably SEZ 23B neurons in addition to sensory neuron afferents (arrows). (F) Close-up of SEZ to highlight the corresponding cell bodies (arrowhead).

(A–C) Confocal stack of larval VNC displaying the overlapping expressions between transcription factors identified from scRNAseq data (Fkh, Kn, and Sp1; green in (A), (B), and (C), respectively) and Hb9 (magenta) in three lineages: 4B, 10B, and 16B (dashed lines). Asterisk in A indicates the Fkh+Hb9- 0 A lineage neurons. (D) Sox21a-GAL4 driven UAS-GFP (green) marks lineage 2 A neurons. (E) HmxGFSTF reporter (green) marks lineage 17 A neurons. (F, G) Wild-type MARCM clones (green) immunostained for Tj (magenta). The insets show the clone location in the VNC counterstained with CadN (blue). (F) Tj marks subpopulations of neurons in lineage 0 A in the T2 segment. These neurons likely belong to cluster 88, the only Tj+ 0A cluster in scRNAseq data. (G) Tj marks nearly all neurons of lineage 21 A in the T1 segment. Lineage identification of MARCM clones was performed based on neuronal projections detailed in Truman et al., 2004; Kanca et al., 2019. scRNAseq clusters with the corresponding lineages shown under each panel. Only one thoracic segment is shown. Neuroglian-specific antibody BP104 labels axon bundles of all lineages (magenta in D-E).

CRISPR-mediated insertion of Trojan Exons.

(A) Construction of CRISPR donor plasmids. For each gene of interest (GOI), a fragment is synthesized into the EcoRV restriction site of pU57_gw_OK2 as described before (Gratz et al., 2014). Briefly, this fragment contains a small sequence of the tRNA spacer, the gRNA against the gene of interest (GOI) (turquoise) and the Left HA and Right HA (turquoise) separated by a spacer containing SacI and KpnI restriction sites (black). A hemidriver cassette (gray, also see B) flanked by SacI and KpnI restriction sites is directionally cloned in between the HAs. (B) Six plasmids containing hemidriver cassettes (gray box) flanked by SacI and KpnI were made in the pBS-KS plasmid backbone. Each plasmid contains either a split-GAL4-DBD or p65.AD in phase 0, 1, and 2. Each hemidriver furthermore contains a 5’attP and FRT sequences, followed by a linker, splice acceptor (SA) and T2A proteolytic cleavage site. The linker length varies to keep the hemidriver in phase with the preceding exon (linker length: 24 nucleotides phase 0, 41 nucleotides phase 1 or 40 nucleotides phase2). An hsp70 termination sequence is introduced at the 3’end of the hemidriver followed by a splice donor (SD), FRT, and attP sequence. Note that the DBD cassettes do not contain a splice donor to keep them consistent with previously published split-GAL4 Trojan exon donors (Lacin et al., 2019). (C) The HAs promote HDR, and the entire hemidriver cassette is inserted at the site of the CRISPR/CAS9 cut, targeted by recognition sequence the gRNA-GOI. The attP sites allow for future cassette exchange with RMCE and genetic crosses.

Figure 3—figure supplement 3
Direct tagging with CRISPR.

Schematic representation of the direct tagging method that establishes split-GAL4DBD lines without any cloning. The gRNA against the gene of interest (GOI) cuts in the direct vicinity of the stop codon (+/-20 nt). The left HA 3’ end reaches up to, but does not include the stop codon, and the right HA 5’ end starts at the first nucleotide of the 3’ UTR. This ensures that the T2A-DBD fragment will be inserted at the 3’ end of the gene and is translated in frame with the GOI. (A) Construction of the CRISPR donor for direct tagging. A fragment that contains a small portion of the tRNA spacer, the gRNA-GOI, and the LHA, T2A-DBD, and RHA sequence is directly synthesized into the EcoRV site of pU57_gw_OK2. (B) Upon embryo injection, expression of gRNA1 linearizes the donor constructs, and the LHA-T2A-DBD-RHA fragment is used for CRISPR/Cas9 guided HDR. As a result, the T2A-DBD is inserted in frame at the 3’ end of the gene, and endogenous 3’ UTR posttranslational regulation mechanisms remain intact.

Neurons of hemilineage 4B show profound morphological changes during development.

Projection of confocal stacks showing the morphology of 4B neurons (green) marked with the ap-GAL4AD and fkh-GAL4DBD driver combination across different developmental time points during metamorphosis: 0, 3, 12, 24, and 48 hr after puparium formation (APF). The VNC is counterstained with CadN (magenta). Cell bodies of 4B neurons in the T3 region are marked with asterisks. (A–F) Complete projections in T2-T3 segments. Anterior (A) up; posterior (P) down. (A’-F’) Transverse views of the entire T3 segments across the dorso-ventral (D–V) axis; Dorsal is up. Arrowheads in B’ mark growth cones. Arrowheads in C’ mark three new branches towards the medial (m), lateral (l) and dorsal (d) part of the leg neuropil. Scale bar is 20 micron.

Acj6-positive neurons in the VNC are glutamatergic or cholinergic.

(A–C) Split-GAL4 line reporting Acj6 expression intersected with a cognate split-GAL4 line reporting the expression of Gad1, ChAT or VGlut to visualize GABAergic, cholinergic, and glutamatergic populations of Acj6-positive neurons, respectively. The VNC is counterstained with CadN (magenta). (A) Split-GAL4 combination acj6-GAL4AD, gad1-GAL4DBD>UAS-GFP driven UAS-GFP shows that the optic lobes contain cholinergic Acj6-positive neurons in addition to a few clusters of neurons with prominent long projections. In the VNC, two cholinergic clusters per hemisegment corresponding to 8B (arrowheads) and 23B (arrows) hemilineages are labeled in addition to some sensory neurons (asterisks). (B) Split-GAL4 combination acj6-GAL4AD, VGlut-GAL4DBD> UAS-GFP marks a single glutamatergic lineage in the dorsal part of the brain and one 9 A glutamatergic cluster in the VNC. (C) Split-GAL4 combination acj6-GAL4AD, gad1-GAL4DBD>UAS-GFP marks two GABAergic lineages in the brain and nothing in the VNC.

Behavioral analysis with targeted lineage manipulation.

(A–D) Optogenetic activation of hemilineage 8 A in the VNC triggers jump behavior. lim3-GAL4DBD; c15-GAL4AD-driven CsChrimson::mVenus (green) targets 8B neurons in the VNC but also shows an unwanted broad brain expression (A), which can be suppressed via an additional layer of intersection using teashirt (tsh)-lexA-driven FLP strategy (B). (C, D) Overlay of video frames to capture the jump sequence induced by optogenetic activation of lineage 8B in the VNC. Intact flies (C) and decapitated flies (D) jump without raising their wings upon optogenetic activation, but decapitated flies were slower to initiate the jump. (E) Optogenetic activation of hemilineage 9 A induces forward walking in decapitated flies. (F, G) Clonal stimulation of hemilineage 12 A in the VNC in decapitated flies induces bilateral wing opening and single-step behavior. (F) Confocal stack displaying the lineage 12 A clone that extends from T2 into T1 and T3. (G) Overlay of movie frames. The fly folds both wings outward and swings its right front leg forward upon optogenetic activation. (H, L) Optogenetic activation of hemilineage 21 A in the VNC on a tethered, intact fly triggers flexion of the tibia-femur joint. (H) Without stimulus, all the legs move erratically in response to being tethered. (I) Upon optogenetic activation, all legs are pulled toward the body, the tibia-femur joints are flexed, and animals stay in this position until the end of stimulus. (J) Overlay of the movie shown in panel H and I, zoomed in on the left T1 leg. Note how the leg is pulled towards the body upon activation (520 ms) compared to its more lateral position without activation (315 ms). (K, L) Elimination of 21 A neurons makes hind leg femur-tibia joints protrude laterally (L) compared to control animals (K). For all overlays of movies, green display frames without optogenetic activation, magenta with optogenetic activation.

Giant fiber (GF) connectome.

Synaptic connectivity of the GF neuron extracted from the data generated by Marin et al., 2024. (A–C) Analysis of GF input connections. (D–F) Analysis of GF output connections. (A) Count of neurons per hemilineage that form synapses with GF dendrites. A total of ten hemilineages form synapses with GF dendrites. Five neurons originate from hemilineage 8B, six from hemilineage 7B, five from lineage 5B, and three from lineage 21 A. (B) Combined connectivity per hemilineage, cumulative count of synapses between GF dendrites and hemilineage neurons. The connectivity between hemilineage 8B and the GF is significant, spanning 339 synapses. Hemilineage 7B, 5B, and 21 A forms 45, 205, and 108 connections, respectively. (C) Weighted connectivity per hemilineage, calculated as the cumulative count of synapses between GF dendrites and hemilineage neurons, divided by the total number of GF output connections observed at a threshold of five synapses per neuron. Hemilineage 8B contributes heavily, making up 25% of GF input, followed by 15% from lineage 5B. Lineage 7B contributes 3.3% and lineage 21 A 8%. (D) Count of neurons per hemilineage that form synapses with GF axons. A total of 13 hemilineages are downstream synaptic partners of the GF. Of those, the synapses formed with lineage 8B are most divergent and span 12 neurons. (E) Combined connectivity per hemilineage, cumulative count of synapses between GF axons and hemilineage neurons. Hemilineage 8B makes 208 synaptic contacts. Hemilineages 18B and 6B also form strong connections, 206 and 121 connections, albeit with fewer neurons (5 and 6, respectively). (F) Weighted connectivity per hemilineage, calculated as the cumulative count of synapses between GF axons and hemilineage neurons, divided by the total number of GF output connections observed at a threshold of five synapses per neuron. 12.5% of output GF synaptic contacts are made with hemilineage 8B, followed by 12.4% with lineage 18B and 7.3% with lineage 6B.

Overview of behavioral phenotypes upon optogenetic activation of specific hemilineages.
LineageGenotype: PhenotypeVideos
0Atj-p65.AD, inv-GAL4-DBD: No apparent behavioral response observed in response to acute optogenetic activation.N/A
1ADr-p65.AD, Ets21C-GAL4-DBD: Activation in both intact and decapitated animals drove leg extension making fly taller. Our observation differed from previously observed phenotypes of erratic forward locomotion, occasionally interrupted by grooming in decapitated animals (Harris et al., 2015).Figure 3—video 1; Figure 3—video 2
1BH15-p65.AD, HLH4C-GAL4-DBD: Activation in both intact and decapitated flies drives leg rotational movement causing the joint between the femur and tibia to bend laterally, most pronounced by the hind legs.Figure 3—video 3; Figure 3—video 4
2AVGlut-p65.AD, Sox21a-GAL4-DBD: Activation in intact animals drove high-frequency wing flapping, consistent with the findings of Harris et al which showed the same phenotype with the decapitated flies. In our experiments with decapitated animals, no wing buzzing was observed, and only halteres moved ventrally upon stimulation.Figure 3—video 5 ; Figure 3—video 6
4Bap-p65.AD, HGTX-GAL4-DBD: Activation causes a full extension of all the legs in both decapitated and intact flies.Figure 3—video 7; Figure 3—video 8
5Bvg-p65.AD, toy-GAL4-DBD: Activation of 5B neurons halts almost every movement in the animal, causing walking, grooming, flying (tethered flight assay), and feeding flies to halt these behaviors. Decapitated animals also halt their grooming activity in response to 5B activation. Active 5B neurons also halt the larval locomotion.Figure 3—video 9; Figure 3—video 10; Figure 3—video 11; Figure 3—video 12
6BCG4328-p65.AD, vg-GAL4-DBD: Activation in intact animals drove inhibition in wing buzzing and leg movements of the tethered flies. Activation in decapitated animals halted sporadic leg movements and drove a subtle change in the posture.Figure 3—video 14; Figure 3—video 15
7Bsv-p65.AD, unc-4-GAL4-DBD: Upon 7B activation, both decapitated and intact animals raised their wings and attempted take-offs, but only a few showed modest take-off behavior. We also observed tibia levitation in response to activation. Harris et al. observed robust take-off behavior.Figure 3—video 16; Figure 3—video 17; Figure 3—video 18
8Aey-p65.AD, ems-GAL4-DBD: Activation brings the body of the fly closer to the ground likely flexing leg segments in both intact and decapitated animals. Harris et al. observed minimal effects after activation.Figure 3—video 19; Figure 3—video 20
8BC15-p65.AD, Lim3-GAL4-DBD: Activation drove intact animals lean backward and take-off. A few animals initiated wing flapping after the jump; others failed to initiate wing flapping and fell after the jump, then they jumped again under the continuous activation. Decapitated animals showed a similar response but never initiated the wing flapping after the take-off.Figure 3—video 21; Figure 3—video 22-2
9ADr-p65.AD, Gad1-GAL4-DBD: Activation in intact animals drove erratic forward locomotion of the animal. Activation in tethered intact flies restricted the legs to stay in a specific posture. In decapitated animals, bodies were lowered toward the ground with legs becoming more splayed for approximately two seconds before occasional forward locomotion and leg grooming, consistent with previous research by Harris et al.Figure 3—video 23; Figure 3—video 24; Figure 3—video 25
9Bacj6-p65.AD, VGlut-GAL4-DBD: Activation in intact animals did not lead to any robust behavior; occasionally animals changed their posture mildly. Decapitated animals halted their grooming in response to 9B activation. This halting behavior was less penetrant compared to the halting behavior observed with 5B activation.Figure 3—video 26; Figure 3—video 27;
10BHb9-p65-AD, sens-2-GAL4-DBD: Activation in intact animals drove erratic walking behavior. 10B activation in decapitated animals drove leg extension and body twisting. Our findings differed from Harris et al., 2015, which showed erratic leg movements causing backward locomotion with occasional wing flicking and buzzing.Figure 3—video 28; Figure 3—video 29;
11 Atey-VP16.AD, unc-4-GAL-4-DBD: Low intensity light activation drove lateral wing waving with occasional jumping, while high intensity activation drove wing buzzing and jumping in intact and decapitated animals.Figure 3—video 30; Figure 3—video 31; Figure 3—video 32; Figure 3—video 33
11Beve-p65.AD, Gad1-GAL4-DBD: Harris et al. observed take-off behavior after activation of the 11B neurons. However, upon light activation, we observed wing movements without any take-off behavior. The wings moved from side to side in a buzzing behavior.Figure 3—video 34; Figure 3—video 35
12 ATfAP2-p65.AD, unc-4-GAL4-DBD: CsChrimson expression showed a lethal phenotype with no surviving adults. We generated lineage clones using TfAP-2-GAL4. Animals expressing CsChrimson in 12 A neurons in one side of the T1 segment showed a single swing movement of the leg that is located on the same side as the animal lineage clone. We also observed bilateral wing buzzing.Figure 3—video 36; Figure 3—video 37
13 Admrt99B-p.65AD, dbx-GAL4-DBD: Upon 13 A activation, intact flies halt their walking and grooming behaviors and change the body posture, making flies slightly taller due to likely femur-coxa extension. Decapitated flies also halt the grooming behavior in response to 13 A activation. Both intact and decapitated flies buzz their wings in response to activation, a phenotype likely arising from contaminating neurons.Figure 3—video 38; Figure 3—video 39
13BD-VP16.AD, vg-GAL4-DBD: Intact flies lost control of their legs and fell on their back with uncoordinated leg movements upon activation of 13B neurons. Decapitated flies responded with a postural change and a weak leg extension phenotype.Figure 3—video 40; Figure 3—video 41
14 ADr-p65.AD, toy-GAL4-DBD: Activation caused intact animals to fall on their back or side with uncoordinated leg movements; flies remained uncoordinated until the cessation of the stimulus. In decapitated animals, activation drove the femur-tibia joint to move anteriorly, most pronounced in the middle legs. We also observed flexion of the legs.Figure 3—video 42; Figure 3—video 43
15BVGlut-p65.AD, HGTX-GAL4-DBD: Upon light stimulation in both intact and decapitated flies, the legs showed a severe flexing phenotype. The legs flexed tightly against the body with the flies falling into a fetal position until after light stimulation ended.Figure 3—video 44; Figure 3—video 45
16BHb9-p65.AD, Bi-GAL4-DBD: Activation in both intact and decapitated animals drove flexion at the femur-tibia joint and coxa-femur axis joint causing the animal to sink lower to the ground.Figure 3—video 46; Figure 3—video 47
17 Aunc-4-p65.AD, Hmx-GAL4-DBD: Activation of 17 A neurons drove flexion of all the leg segments in both decapitated and intact animals.Figure 3—video 48; Figure 3—video 49
19 Ascro-p65.AD, dbx-GAL4-DBD: Activation in decapitated animals drove flexion at the tibia-tarsus joint as well as anterior movement of the femur-tibia axis. In intact animals, we observed severe flexing of the legs against the body, making flies fall on their back. Harris et al. observed a leg-waving phenotype of the T2 legs in decapitated animals after stimulation.Figure 3—video 50; Figure 3—video 51
21 ADr-p65.AD, tj-GAL4-DBD: Activation of 21 A neurons in decapitated animals drove flexion of the legs, bringing the body of the fly closer to the ground. We observed a similar phenotype in intact animals tethered to a pin.Figure 3—video 52; Figure 3—video 53
23Bunc-4-p65.AD, acj6-GAL4-DBD: Activation caused intact animals to fall on their back due to uncoordinated leg movements and sustained flexion or extension of the leg segments; flies remained uncoordinated until the cessation of the stimulus. Flies also showed increased grooming activity. We also observed wing buzzing in response to activation. Decapitated animals showed similar responses.Figure 3—video 54; Figure 3—video 55
