ecdysone

A Dictionary of Biology | 2004 | © A Dictionary of Biology 2004, originally published by Oxford University Press 2004. (Hide copyright information) Copyright

ecdysone A steroid hormone, secreted by a pair of prothoracic glands in the thorax of insects and by Y organs in crustaceans, that stimulates moulting (see ecdysis) and metamorphosis. In insects its release is stimulated by prothoracicotropic hormone. It acts on specific gene loci, stimulating the synthesis of proteins involved in these bodily changes. Some plants contain phytoecdysones, which are structurally similar to the insect ecdysones. They may help to protect the plant by interfering with the moulting cycle of insect pests that consume plant tissue.
