Molecular and functional analysis of eclosion hormone-like gene involved in post-eclosion behavior in a beetle

Journal of Insect Physiology, 2022
Eclosion hormone (EH) is a neurohormone that plays a key role in the regulation of insect pre-ecdysis behavior at the end of each molt. Previous research has reported more than one EH gene was found in certain insects, with their functions and mechanisms still unclear.

Eclosion hormone activity in haemolymph of eclosing silkmoth, Bombyx mori

Journal of Insect Physiology, 1984
Abstract The presence of eclosion hormone in the haemolymph of eclosing adults of the silkworm, Bombyx mori , was demonstrated to provide evidence that the hormone is involved in the induction of eclosion of this insect. The eclosion of the adult occurred within 55–75 min after light-on, when the pupae had been kept under conditions of 16 h light ...

Alteration of the eclosion rhythm and eclosion behavior in the flesh fly, Sarcophaga crassipalpis, by low and high temperature stress

Journal of Insect Physiology, 1994
Abstract Heat shock (45°C), cold shock (−10°C), and indirect chilling injury (a prolonged exposure to 2°C) did not interfere with the continuation of pharate adult development in the flesh fly, Sarcophaga crassipalpis, but such flies failed to eclose properly when the exposure was of sufficient duration.

Cellular signaling in eclosion hormone action

Journal of Insect Physiology, 2002
Eclosion hormone (EH) is a 62 amino acid neuropeptide that plays an integral role in triggering ecdysis behavior at the end of each molt. At least three populations of cells are thought to be targets for EH, each of which show an EH-stimulated increase in the intracellular messenger guanosine 3', 5' cyclic monophosphate (cGMP).

The Circadian Control of Eclosion

Chronobiology International, 2003
Eclosion is the stage in development when the adult insect emerges from the shell of its old cuticle. The sequence of behaviors necessary for eclosion is coordinated by an integrated system of hormones and is activated by hormones that relay developmental readiness.

Bombyx Eclosion Hormone

1990
Adult eclosion of the silkworm, Bombyx mori, occurs during a specific period of the day under the control of eclosion hormone (EH). Bombyx EH was extracted from the pupal and adult brains (Fugo, et al., 1982), and also the embryos of B. mori (Chen, et al., 1986). In 1985, Bombyx EH was first isolated from the pharate adult heads of B.

Expression of a silkworm eclosion hormone gene in yeast

Biochemical and Biophysical Research Communications, 1990
Recombinant silkworm eclosion hormone was produced for the first time in yeast which was transformed with a shuttle plasmid containing a construct coding a signal peptide and the mature sequence of the silkworm eclosion hormone. Successfully transformed yeast processed recombinant silkworm eclosion hormone I (EH-I) and transported it to periplasm at ...
