Elemental composition of marine Prochlorococcus and Synechococcus: Implications for the ecological stoichiometry of the sea
Elemental composition marine Prochlorococcus Synechococcus ecological stoichiometry
2014/5/21
The elemental composition of marine cyanobacteria is an important determinant of the ecological stoichiometry in low-latitude marine biomes. We analyzed the cellular carbon (C), nitrogen (N), and phos...
Variations in Synechococcus cell quotas of phosphorus, sulfur, manganese, iron, nickel, and zinc within mesoscale eddies in the Sargasso Sea
phosphorus sulfur manganese iron
2014/4/16
The quotas of P, S, Mn, Fe, Ni, and Zn in individual Synechococcus cells collected from the surface and deep
chlorophyll maximum (DCM) layer of three mesoscale eddies in the Sargasso Sea were measure...
摘要 2004年首次在南海北部海域使用选择性代谢抑制剂技术进行了Synechococcus和Prochlorococcus生长率和被摄食消亡率的研究。研究结果表明，Synechococcus高丰度值出现在次表层(15 m或20 m)，位于温跃层之上，高生长率往往出现在丰度最大值水层上方；Prochlorococcus丰度在夏季出现次表层最大值，与温跃层深度基本一致，表层生长率高于真光层底部。Syn...
Bio-optical consequences of viral infection of phytoplankton: I. Experiments with the cyanobacterium, Synechococcus sp.
Bio-optical consequences viral infection of phytoplankton I. Experiments with the cyanobacterium Synechococcus sp.
2014/4/23
Four strains of the cyanobacteria, Synechococcus, were infected with viruses isolated and purified from coastal waters of the Gulf of Maine. Changes in host and virus concentration were observed in ti...
Structure of synechobactins, new siderophores of the marine cyanobacterium Synechococcus sp. PCC 7002
synechobactins marine cyanobacterium Synechococcus
2014/5/13
The coastal marine cyanobacterium Synechococcus sp. PCC 7002 produces three amphiphilic siderophores, synechobactins A-C, under iron-limiting growth conditions. The synechobactins are comprised of a c...
Dimethylsulfoniopropionate(DMSP) assimilation by Synechococcus in the Gulf of Mexico and northwest Atlantic Ocean
Dimethylsulfoniopropionate Synechococcus
2014/5/13
A variety of bacterial phylogenetic groups assimilate dimethylsulfoniopropionate (DMSP), an organic sulfur
compound that can satisfy most of the sulfur (S) demand of bacteria in the surface waters of...
Expression of the nitrogen stress response gene ntcA reveals nitrogen-sufficient Synechococcus populations in the oligotrophic northern Red Sea
nitrogen stress response gene nitrogen-suffi cient Synechococcus
2014/5/13
Determining the nitrogen (N) status of phytoplankton is important for understanding primary production and N
cycling in marine ecosystems. We assayed transcript levels of the N regulatory gene ntcA t...
Production of cobalt binding ligands in a Synechococcus feature at the Costa Rica upwelling dome
cobalt binding ligands Synechococcus feature Costa Rica upwelling dome
2014/5/8
The Costa Rica upwelling dome (CRD; ~8.67°N and 90.6°W) was characterized chemically for cobalt and nickel abundances and speciation and biologically using cyanobacterial abundances and phylogeny. Tot...
Elemental composition of single cells of various strains of marine Prochlorococcus and Synechococcus using X-ray microanalysis
Elemental composition single cells various strains marine Prochlorococcus Synechococcus X-ray microanalysis
2014/5/21
We measured the elemental composition of single cells from six strains of marine Prochlorococcus and two strains of marine Synechococcus by X-ray microanalysis in the transmission electron microscope ...
A Synechococcus serotype is found preferentially in surface marine waters
Synechococcus serotype surface marine waters
2014/5/21
In marine ecosystems, gradients of light, temperature, and nutrients occur horizontally (coastal to offshore) and vertically. The extent to which microorganisms acclimate or speciate in response to th...
Uptake and efflux of 64 Cu by the marine cyanobacterium Synechococcus (WH7803)
the marine cyanobacterium Synechococcus Uptake
2014/5/20
The uptake and efflux of
64
Cu was studied in the marine cyanobacterium Synechoccous strain WH7803 (DC2).
Uptake followed classical Michaelis-Menten type kinetics in metal-buffered seawater. ...
Utilization of different nitrogen sources by the marine cyanobacteria Prochlorococcus and Synechococcus
different nitrogen sources marine cyanobacteria Prochlorococcus Synechococcus
2014/5/27
Prochlorococcus is the most abundant phytoplankter throughout the photic zone in stratified marine waters and experiences distinct gradients of light and nitrogen nutrition. Physiologically and geneti...
