Nitrate uptake in the scleractinian coral Stylophora pistillata
We assessed the uptake rates of nitrate by the scleractinian coral Stylophora pistillata by following 15N from seawater into the coral tissue. Two sets of corals were first prepared, with ‘‘nitrate-enriched’’ corals grown in 5 mmol L21 NO and control corals grown in #1 mmol L21 NO . Uptake rates at 0.3 and 3 mmol L21 [15N]NO 2 2 2 3 3 3 were then measured. Most of the %15N enrichment occurred i...
متن کاملHigh phosphate uptake requirements of the scleractinian coral Stylophora pistillata.
Several untested aspects of the regulation of inorganic nutrient uptake were examined using nutrient depletion experiments with the symbiotic coral Stylophora pistillata. The total inhibition of phosphate uptake in artificial seawater lacking sodium indicates the involvement of a sodium/phosphate symporter for the uptake of phosphate across host membranes. Addition of ammonium or nitrate (up to...
متن کاملTranscriptome Analysis of the Scleractinian Coral Stylophora pistillata
The principal architects of coral reefs are the scleractinian corals; these species are divided in two major clades referred to as "robust" and "complex" corals. Although the molecular diversity of the "complex" clade has received considerable attention, with several expressed sequence tag (EST) libraries and a complete genome sequence having been constructed, the "robust" corals have received ...
متن کاملUptake of ammonium by the scleractinian coral Stylophora pistillata: Effect of feeding, light, and ammonium concentrations
Experiments were designed to assess the uptake rates of 0.2, 1, and 5 mM ammonium by the scleractinian coral Stylophora pistillata maintained under different feeding regimes (highly fed, slightly fed, and starved) for 4–8 weeks. NH4 was used to follow the incorporation of nitrogen in the zooxanthellae or in the animal tissue and to calculate uptake rates. After 4 or 8 weeks, fed corals containe...
متن کاملUptake of dissolved free amino acids by the scleractinian coral Stylophora pistillata.
This study was designed to assess the importance of dissolved free amino acids (DFAA) as a nitrogen source for the scleractinian coral Stylophora pistillata. For this purpose, experiments were performed using (15)N-enriched DFAAs, and %(15)N enrichment was measured both in animal tissue and zooxanthellae at different DFAA concentrations, incubation time and light levels. As previously observed ...
