Isolation of an eclosion hormone gene from the cotton bollworm, Helicoverpa armigera: temporal and spatial distribution of transcripts.

Abstract

The cDNA encoding eclosion hormone (EH), which plays an integral role in triggering ecdysis behavior at the end of each molt, was cloned from the cotton bollworm, Helicoverpa armigera (Har) (Lepidoptera: Noctuidae). The EH polyprotein precursor contains a 26-amino acid signal peptide and a single 62-amino acid mature EH. Compared the mature Har-EH with… (More)
