Description
Summary:L- alpha , omega -diamino acids and their derivatives facilitate the chemically induced settlement and metamorphosis of larvae of Haliotis rufescens , a marine gastropod. Organic inducers of settlement and metamorphosis used in this study include gamma -aminobutyric acid (GABA), muscimol, and the macromolecular fraction of a cell-free extract of the naturally recruiting crustose red alga, Lithothamnium californicum . An inorganic inducer of settlement and metamorphosis, ionic potassium, is also used. Allosteric regulation of chemosensory receptors controlling larval metamorphosis is suggested by the results of this study.
