The role of the tracheae and musculature during pathfinding of Drosophila embryonic sensory axons.

Abstract excerpt

Developing sensory axons were studied in Drosophila embryos which carried a mutation in the trachealess and/or the twist gene. In these embryos, the tracheae and/or somatic muscles, which represent part of the substrate on which sensory axons normally grow, are absent. The results demonstrate that in each of these three mutant backgrounds, the majority of sensory nerves form normally. This indicates that neither...
