| Outline of Final Research Achievements |
Sex-determining systems can be broadly divided into two categories: genetic and environmental. We previously identified a gene that regulates environmental sex determination in Daphnia. Interestingly this gene was homologous to doublesex genes that are regulators of genetic sex determination, suggesting that there is a previously unidentified link between genetic and environmental sex determination. In this study, we aimed to find factors that control doublesex gene expression of Daphnia. RNA-seq analysis and comparative studies of the genes involved in sex determination enabled us to find candidates of regulators of doublesex gene.
