(Submitter supplied) We have adapted the DamID protocol for use with high throughput sequencing. We have used DamID to identify the positions within the Drosophila genome where the transcription factor DSX is bound. We sequenced DpnI-digested genomic DNA from fly tissues containing UAS-Dam (control) or UAS-Dam-DsxF or UAS-Dam-DsxM.

(Submitter supplied) The Drosophila sex determination hierarchy consists of a splicing cascade with sex-specific transcription directing somatic sexual dimorphism. Our understanding of this pathway, and many others, is incomplete. Here we pioneer an approach to expand our knowledge of gene regulatory networks (GRNs) by leveraging natural genetic variation. This approach is generalizable to any natural population, including humans. more...

(Submitter supplied) Drosophila melanogaster adult males perform an elaborate courtship ritual to entice females to mate. fruitless (fru), a gene that is one of the key regulators of male courtship behavior, encodes multiple male-specific isoforms (FruM). These isoforms vary in their carboxy-terminal zinc finger domains, which are predicted to facilitate DNA binding. By over-expressing individual FruM isoforms in fru-expressing neurons in either males or females and assaying the global transcriptional response by RNA-sequencing, we show that three FruM isoforms have different regulatory activities that depend on the sex of the fly. more...

(Submitter supplied) The Drosophila genitalia develop from an imaginal disc that is patterned during the larval period and undergoes morphogenesis during the pupal period. Although the genetic hierarchy that controls sexual identity in Drosophila is well characterized, the downstream genes that effect sexually dimorphic development of the genitalia are largely unknown. We used microarrays to profile gene expression in female and male genital imaginal discs at three time points during development: late third-instar larvae (L3), pupae approximately 6 hours after puparium formation (P6) and pupae approximately 20 hours after puparium formation (P20). more...

Analysis of female or male genital discs dissected during early morphogenesis (L3, P6, or P20). In flies, the sex-determination hierarchy terminates in the doublesex (dsx) gene. Results provide insight into molecular mechanisms downstream of dsx underlying sex-specific differentiation of genitalia.

(Submitter supplied) Purpose: Sexual dimorphisms fuel significant intraspecific variation and evolutionary diversification. Yet the developmental-genetic mechanisms underlying sex-specific development remain poorly understood. We focused on the conserved sex-determination gene doublesex (dsx) and the mechanisms by which it mediates sex-specific development in a species of horned beetle by combining systemic dsx knockdown, high-throughput sequencing of diverse tissues, and a genome-wide analysis of Dsx binding sites. more...

(Submitter supplied) We recently identified a missense mutation in Nucleoporin107 (Nup107; D447N) underlying XX-ovarian-dysgenesis (XX-OD), a disorder characterized by underdeveloped and dysfunctional ovaries. Specific knockdown of Nup107 in the somatic gonadal cells and moreover, modelling of the human mutation in Drosophila result in ovarian-dysgenesis-like phenotypes in female flies. The aberrant phenotypes in larval and adult ovaries compromised for Nup107 are associated with hyperactivation of BMP signalling. more...

(Submitter supplied) Drosophila melanogaster undergoes a complete metamorphosis, during which time the larval male and female forms transition into sexually dimorphic, reproductive adult forms. To understand this complex morphogenetic process at a molecular-genetic level, we performed whole genome microarray analyses. Genes were identified that were expressed during metamorphosis in both somatic and germline tissues of males and females. more...

(Submitter supplied) Drosophila melanogaster undergoes a complete metamorphosis, during which time the larval male and female forms transition into sexually dimorphic, reproductive adult forms. To understand this complex morphogenetic process at a molecular-genetic level, we performed whole genome microarray analyses. In somatic tissues at 48 hour After Puparium Formation (APF), 173 sex-biased transcripts that likely function downstream of the doublesex (dsx) branch of the sex determination hierarchy were identified. more...

(Submitter supplied) The Drosophila sex determination hierarchy controls all aspects of somatic sexual differentiation, including sex-specific differences in adult morphology and behavior. To gain insight into the molecular-genetic specification of reproductive behaviors and physiology, we identified genes expressed in the adult head and central nervous system that are regulated downstream of sex-specific transcription factors encoded by doublesex (dsx) and fruitless (fru). more...

(Submitter supplied) The survival and reproductive success of animals depends on the ability to harmonize their external behaviors with their internal states. For example, females conduct numerous social programs that are distinctive to virgins compared to post-mated and/or pregnant individuals. In Drosophila, the fact that the post-mating switch is initiated by seminal factors implies the default state as virgin. Recently, we uncovered molecular and genetic control of the female virgin state. more...
