cell body & serotonin neuron, with Scer\GAL4eg-Mz360
serotonin neuron & ventral nerve cord, with Scer\GAL4eg-Mz360
In leaEP2582; Scer\GAL4eg-Mz360 embryos, serotonergic axons do not cross the midline. Despite their defects in serotonergic neuronal axon guidance, these neurons retain their normal ability to take up serotonin. Unlike wild-type serotonergic neurons, the ability of serotonergic neurons in the ventral nerve cord of stage 16 leaEP2582; Scer\GAL4eg-Mz360 embryos to take up serotonin is not lost when their axonal contacts with the midline are severed. The cell bodies of serotonergic neurons in the ventral nerve cord of stage 16 leaEP2582; Scer\GAL4eg-Mz360 embryos are shifted laterally compared to wild-type.
Antennal commissure formation is abolished and glomerular morphology is disrupted in the antennal lobes of leaEP2582; Scer\GAL4SG18.1 flies.
Abdominal lch5 chordotonal organs are transformed so that they resemble thoracic dch3 chordotonal organs in larvae expressing leaEP2582 under the control of Scer\GAL4elav-C155. The transformed "lch5" chordotonal organs are displaced dorsally in the ectoderm. They have the usual number of five neurons per cluster, but their dendrites and support cells show a variety of orientations, which range from the ventral orientation typical of dch3 organs, through intermediate bent orientations, to orientations similar to those of normal lch5 organs. At 29oC, 44% of abdominal segments have partial or complete transformation of lch5 chordotonal organ morphology. At 25oC, 32% of abdominal segments have partial or complete transformation of lch5 chordotonal organ morphology. Defects indicating transformation of the lch5 chordotonal organs can be detected as early as stage 14 in embryos expressing leaEP2582 under the control of Scer\GAL4elav-C155. The cap cells of the transformed "lch5" organs always follow the orientation of the transformed neurons. At 29oC, 30.5% of abdominal segments have partial or complete transformation of lch5 chordotonal organ morphology towards that of the thoracic dch3 chordotonal organs, in larvae expressing leaEP2582 under the control of Scer\GAL4ato.3.6. Some abdominal lch5 chordotonal organs fail to migrate ventrally (as occurs in wild type) in embryos expressing leaEP2582 under the control of Scer\GAL4ato.3.6. Some of these "stalled" abdominal clusters extend projections dorsally. At 29oC, 17% of abdominal segments have partial or complete transformation of lch5 chordotonal organ morphology towards that of the thoracic dch3 chordotonal organs, in embryos expressing leaEP2582 under the control of Scer\GAL448Y.
ventral nerve cord commissures in stage 17 leaEP2582; Scer\GAL4sca-4512 embryos are missing or fused.
Mutant larvae expressing leaEP2582 under the control of Scer\GAL4elav-C155 have ISN neuron pathfinding defects.
When expression of leaEP2582 is driven by Scer\GAL4elav.PLu, commissures are lost.
Expression of leaEP2582 under the control of Scer\GAL4ap-md544 causes ap-expressing neurons to move laterally (relative to wild type) and extend anteriorly in a specific location between the intermediate and lateral Fas2-expressing pathways. The ap-expressing axons from neighbouring segments appear to pick the same lateral pathway and to fasciculate together as they extend anteriorly from segment to segment. Expression of leaEP2582 under the control of Scer\GAL415J2 results in a bimodal phenotype. The dMP2 and vMP2 axons always appear to extend in a Fas2-expressing pathway, but they are now found in either the intermediate or lateral pathways (they normally extend in the medial pathway). They are usually found in the intermediate pathway and occasionally found in the lateral pathway.

The transformation of abdominal lch5 chordotonal organs to a morphology resembling thoracic dch3 chordotonal organs that is seen in larvae expressing leaEP2582 under the control of Scer\GAL4elav-C155 is still seen if they are also mutant for robo7; 36.4% of abdominal segments have partial or complete transformation of the lch5 organs in the double mutant larvae. The transformation of abdominal lch5 chordotonal organs to a morphology resembling thoracic dch3 chordotonal organs that is seen in larvae expressing leaEP2582 under the control of Scer\GAL4elav-C155 is attenuated if the larvae also carry one copy of sli2; only 17.2% of abdominal segments have partial or complete transformation of the lch5 organs in the double mutant larvae at 25oC.
