| PubMed Abstract | Proper sampling of sensory inputs critically depends upon neuron morphogenesis and expression of sensory channels. The highly stereotyped organisation of the Drosophila peripheral nervous system (PNS) provides a model to study neuronal determination and morphogenesis. Here, we report that Collier/Knot (Col/Kn), the Drosophila member of the COE family of transcription factors, is transiently expressed in the subset of multidendritic arborisation (da) sensory neurons that display an highly branched dendritic arborisation, class IV neurons. When lacking Col activity, class IV da neurons are formed but display a reduced dendrite arborisation. Col control on dendrite branching is distinct from that exerted by Cut, another transcription factor expressed in class IV neurons and necessary for proper dendrite morphogenesis. Col is also required for the class IV da-specific expression of pickpocket (ppk), which encodes a degenerin/epithelial sodium channel subunit required for larval locomotion. Characterisation of the col upstream region identified a 9-kb cis-regulatory region driving col expression in all class IV md neurons, even though these originate from two types of sensory precursor cells. Altogether, these findings indicate that col is required in at least two distinct programs that control the morphological and sensory specificity of Drosophila md neurons. | ||
