Induction of Settling and Metamorphosis of Planktonic Molluscan (Haliotis) Larvae. III: Signaling by Metabolites of Intact Algae is Dependent on Contact

摘要: Classical models of chemical signaling mechanisms which govern various aspects the behavior, reproduction and development animals in aqueous environments have been based largely upon well-characterized systems chemoreception, chemotaxis chemosensory behavior response to concentration gradients freely diffusible inducers or gaseous media (see, for example. Grant Mackie, 1974; Shorey, 1976). In contrast, we recently identified a mechanism induction governing behavioral developmental metamorphosis certain planktonic molluscan larvae is mediated, at least part, by contact-dependent recognition coval’ently complexed (or sequestered) non-diffusing algal metabolites.
