- Title
BEYOND SEQUENCE HOMOLOGY: REDUNDANT AMMONIUM TRANSPORTERS IN A MARINE DIATOM ARE NOT FUNCTIONALLY EQUIVALENT.
- Authors
Allen, Andrew E.
- Abstract
This article reports that there is a great deal of interest in understanding relationships between the availability of different inorganic nitrogen sources and phytoplankton production in the marine environment because measurements of regenerated production and new production provide a means to estimate carbon flux out of the euphotic zone. The concentration of ammonium required to inhibit nitrate uptake rates by half has been shown to be significantly higher for dinoflagellates compared to diatoms and nitrate uptake by both classes of phytoplankton is less inhibited by ammonium at lower growth temperatures.
