Journal ArticleDOI
Phosphonate utilization by the globally important marine diazotroph Trichodesmium.
Sonya T. Dyhrman,P. D. Chappell,Sheean T. Haley,James W. Moffett,Elizabeth D. Orchard,John B. Waterbury,Eric A. Webb +6 more
TL;DR: The induction, by phosphorus stress, of genes from the Trichodesmium erythraeum IMS101 genome that are predicted to encode proteins associated with the high-affinity transport and hydrolysis of phosphonate compounds by a carbon–phosphorus lyase pathway are described.
Journal ArticleDOI
Phosphorus scavenging in the unicellular marine diazotroph Crocosphaera watsonii.
Sonya T. Dyhrman,Sheean T. Haley +1 more
TL;DR: Observations from the C. watsonii WH8501 genome suggest that this organism has the capacity for high-affinity phosphate transport in low-phosphate, oligotrophic systems, although this capacity differs from that of other marine cyanobacterial genera, such as Synechococcus, Prochlorococcus and Trichodesmium.
Journal ArticleDOI
A microbial source of phosphonates in oligotrophic marine systems
Sonya T. Dyhrman,Claudia R. Benitez-Nelson,Elizabeth D. Orchard,Sheean T. Haley,Perry J. Pellechia +4 more
TL;DR: In this paper, the authors used solid-state nuclear magnetic resonance spectroscopy to screen for the presence of phosphonates in cultured strains of Trichodesmium erythraeum.
Journal ArticleDOI
Functional group-specific traits drive phytoplankton dynamics in the oligotrophic ocean.
Harriet Alexander,Mónica Rouco,Sheean T. Haley,Samuel T. Wilson,David M. Karl,Sonya T. Dyhrman +5 more
TL;DR: The results indicate blooms form when phytoplankton are released from limitation by resources and that the mechanistic basis for the success of one functional group over another may be driven by how efficiently the transcriptome is modulated following a nutrient pulse.
Journal ArticleDOI
Long Serial Analysis of Gene Expression for Gene Discovery and Transcriptome Profiling in the Widespread Marine Coccolithophore Emiliania huxleyi
Sonya T. Dyhrman,Sheean T. Haley,Shanda R. Birkeland,Louie L. Wurch,Michael J. Cipriano,Andrew G. McArthur +5 more
TL;DR: The long SAGE analyses have identified many new differentially regulated gene sequences, assigned regulation data to EST sequences with no database homology and unknown function, and highlighted previously uncharacterized aspects of E. huxleyi N and P physiology.
