Expression and Functional Analysis of Gene Responding to High Ammonia Stress in Razor Clam ().

Ammonium transporter 1 (AMT1), a member of ammonia (NH/NH) transport proteins, has been found to have ammonia transport activity in plants and microorganisms. However, the functional characteristics and molecular mechanisms of AMT1 in mollusks remain unclear. The razor clam () is a suitable model species to explore the molecular mechanism of ammonia excretion because of the high concentration of ambient ammonia it is exposed to in the clam-fish-shrimp polyculture system.
