The stereotypical remodeling of the Drosophila mushroom body (MB) during metamorphosis provides a unique system to genetically dissect neuronal remodeling. Here, we uncover the fine temporal transcriptional landscape of MB γ neurons throughout their remodeling phase. To enrich and complement this developmental expression atlas, we also sequenced developing γ neurons perturbed for three key transcription factors known to regulate pruning. Together, these datasets allowed us to construct the developmental and temporal framework of transcriptional modules that together drive remodeling. Moreover, we identified 10 DNA binding proteins that are involved in various aspects of remodeling, and describe their hierarchical relationships. Overall, this study provides the first broad and detailed molecular insight into the complex regulatory dynamics of developmental neuronal remodeling.
