Three Forms of Gonadotropin-Releasing Hormone, Including a Novel Form, in a Basal Salmonid, Coregonus clupeaformis1

Abstract excerpt

Multiple forms of GnRH within individual brains may have different functions. However, some vertebrates such as salmonids continue to reproduce even though they have lost or do not express 1 of the 3 forms of GnRH found in most other teleosts. We examined a basal salmonid, lake whitefish, to determine the mechanism by which a reduction in the number of GnRH forms occurs. We identified for the first time 3...
