chordotonal organ & axon | lateral
mushroom body & axon
Mushroom body neuroblast clones induced using the MARCM system show similar, but milder, phenotypes than do clones of shot3.
Mutant phenotype of lateral chordotonal axons includes: shorter axons.
Defective in navigation through a specific choice point, for a mesodermal substrate, during intersegmental nerve and segmental nerve b pathfinding. Intersegmental nerve projections also prematurely terminated.
Phenotype fully penetrant and highly expressive.
