Nutritional status affects 20-hydroxyecdysone concentration and progression of oogenesis in Drosophila melanogaster

Drosophila egg production depends upon the nutritional available to females. When food is in short supply, oogenesis is arrested and apoptosis of the nurse cells is induced at mid-oogenesis via a mechanism that is probably controlled by ecdysteroid hormone. We have shown that expression of some ecdy...
