| Outline of Final Research Achievements |
The sexual differentiation of somatic cells in Drosophila is controlled by the terminal genes in the sex determination hierarchy; fruitless (fru) and doublesex (dsx). Recent studies revealed that neurons expressing these genes play central role in the courtship behavior. The courtship song produced by a male fly is one of the hallmarks of courtship of Drosophila. To reveal the neural basis for courtship song production, I performed behavioral experiments by using the technique to manipulate neural activity of fru/dsx-expressing neurons. In this study, I identified 4 types of dsx-expressing neurons controlling proper courtship song production.
