Fig. 6. Disruption of Babo and Put signaling induces pathfinding defects.
UAS-babo
I, UAS-put
I or
UAS-tkv
I were expressed using different Gal4 drivers
at 29°C. Motoneuron projections in late stage 16/17 filleted embryos
stained with 1D4. OK6-Gal4 driven expression of Babo
I (A) and
Put
I (B) results in stalling of ISNb axons and thickening of
axon bundles (arrowheads).
