Example sentencesExamples
- Two hormones in particular drive these fundamental processes: ecdysone and juvenile hormone.
- Larval molting in Drosophila, as in other insects, is initiated by the coordinated release of the steroid hormone ecdysone, in response to neural signals, at precise stages during development.
- A pulse of the steroid hormone ecdysone at the onset of metamorphosis triggers the rapid transformation of a flat leg imaginal disc into an immature adult leg, largely through coordinated changes in cell shape.
- Consequently, both the onset and the termination of disc growth are determined by the joint action of ecdysone and juvenile hormone.
- This checkpoint may be controlled by signaling through the steroid hormone ecdysone.
Origin
