Detailed Description
Statement
Reference

MicalK1496/Df(3R)swp2MICAL animals have axon guidance defects in ISNb, characterized by decreased axonal defasciculation/repulsion and a failure of axons to reach their correct targets.

Surviving MicalK1496/Df(3R)swp2MICAL adults almost always have defects in bristle morphology.

The synaptic territory (the muscle area covered by neuromuscular junctions) of MicalI666/MicalK1496 larvae contains clumps of densely packed boutons, many of which appear smaller.

The number of boutons in the cleft between muscles 6 and 7 is increased compared to controls in MicalK1496/Df(3R)swp2MICAL third instar larvae and the muscle 6+7 surface area is also consistently larger than wild type.

The sarcomeric pattern of the somatic muscles is disrupted in MicalK1496 first instar larvae; the myosin filaments are organised in needle-like arrays and oriented along the longitudinal axis of muscle fibres, resembling the normal embryonic pre-sarcomeric state.

The phenotype of irregular flight muscle myofibrils that is seen in MicalK1496/Df(3R)Exel6155 flies is not rescued if they are carrying the P{FlyFos-045847} construct (which contains D. pseudoobscura pseudoobscura fosmid sequence that includes the region orthologous to Mical).
