This study uses comparative single-cell transcriptomics to identify gene expression differences and their role in genital morphogenesis in two Drosophila species.

The paper investigates the regulatory landscape of female and male genital structures in Drosophila melanogaster, finding shared transcription factors and their expression patterns in both sexes.

The paper shows that a Notch signaling center required for a new Drosophila genital structure evolved from a pre-existing role in genital disc eversion.

This study shows that co-opting the trichome genetic network in Drosophila can induce large apical projections on the phallus, demonstrating the flexibility of gene regulatory networks in evolving new morphologies.

The paper examines oviprovector scales in Drosophila species, finding they have divergent sizes and spatial arrangements and are regulated by a conserved gene network similar to trichomes.

The paper investigates how the expansion of the apical extracellular matrix (aECM) contributes to the formation of a novel structure in D. melanogaster.

The paper maps transcription factor expression in Drosophila melanogaster pupal terminalia using RNA-seq and in situ hybridization, revealing structured patterns and creating an online database for future research.

The paper shows how a new trait evolved by integrating the Bric-a-brac transcription factors into a gene regulatory network through cis-regulatory element evolution in Drosophila.
