Project description:Purpose: Mating induces a multitude of changes in female behavior, physiology and gene expression. Interactions between female and male genotype lead to variation in post-mating phenotypes and reproductive success. So far, few female molecules responsible for these interactions have been identified. Methods: We used Drosophila melanogaster from five geographically dispersed populations to investigate such female x male genotypic interactions at the female transcriptomic and phenotypic levels. Methods: Females from each line were singly-mated to males from the same five lines, for a total of 25 combinations. To assess whether female x male genotypic interactions affect the female post-mating transcriptome, next-generation RNA sequencing was performed on virgin and mated females at 5 to 6 hours post-mating. Results: Seventy-seven genes showed strong variation in mating-induced expression changes in a female x male genotype-dependent manner. These genes were enriched for immune response and odorant-binding functions, and for expression exclusively in the head. Conclusions: The transcriptional variation found in specific functional classes of genes might be a read-out of female x male compatibility at a molecular level. Understanding the roles these genes play in the female post-mating response will be crucial to better understand the evolution of post-mating responses and related conflicts between the sexes.

Project description:The female’s reproductive tract is exposed directly to the male’s ejaculate, making it a hotspot for mating-induced responses shortly after mating. In Drosophila melanogaster, changes in the reproductive tract are essential to optimize fertilization. To detect the earliest gene regulatory events that underlie these changes, we measured transcript abundances using RNA-seq and microRNA-seq of reproductive tracts of unmated females and females collected within 10-15 minutes after the end of mating, either to a wildtype male or to a male with defective BMP signaling in secondary cells of the accessory gland, which influences the composition of the male’s ejaculate. We observed transcript abundance changes for genes with roles in tissue morphogenesis, wound healing, the immune response and metabolism. Strikingly, predicted targets of microRNAs that respond to mating are enriched for overlapping functions, suggesting that mating-induced changes are in part regulated by microRNAs. Most of the differentially expressed RNAs are upregulated in response to mating, while most of the differentially expressed microRNAs are downregulated. This pattern suggests a response of activation and de-repression of gene programs that switch the reproductive tract to a “mated” state, rather than a repression of virgin-specific programs. Male genotype did not influence transcript levels, indicating that the earliest transcriptomic responses in the reproductive tract are not dependent on ejaculate components that require BMP signaling in secondary cells. Our results shed light on the molecular changes that accompany very early responses to mating and present candidate genes and microRNAs that can be further examined for their participation in alterations of the reproductive tract microenvironment in response to signals from the male.
