| Outline of Final Research Achievements |
The male reproductive organ accessory glands in Drosophila make components of seminal fluid. We examined the possibility that accessory gland cells function as a nutrient sensor when controlling reproductive ability (fecundity) in response to nutrient conditions. Of the main cells (~ 1,000) and the secondary cells (~ 60), we showed that the nutrient conditions during development change the number and size of secondary cells to optimize male fecundity. In addition, Dve and Abd-B were identified as factors that control gene expression in a nutrient-dependent manner.
