Abstract: Host glutamine synthetase activity decreases in Pocillopora damicornis
(Linnaeus) following exposure of the coral to seawater containing elevated
ammonium (20 uM). Zooxanthellae isolated from these corals exhibited
lower ammonium uptake capacity and glutamine synthetase activity compared
with those from the control corals. Ammonium concentration of the surrounding
seawater had no effect on the NADPH-dependent glutamate dehydrogenase
activity in the host.
