MetabolomicsA Phosphate starvation response gene (psr1-like) is present in Micromonas pusilla and other marine algae and coordinates the metabolic response to phosphate deficiency
Both marine phytoplankton and terrestrial plants have to deal with limited bioavailability of the key life nutrient, phosphate. In freshwater algae and plants, a phosphate starvation response gene (psr1) has been characterized, which encodes for a transcription factor that regulates the metabolic re...

MetabolomicsRelease of Ecologically Relevant Metabolites by the Cyanobacterium, Synechococcus elongatus CCMP 1631
Phytoplankton are known to release organic compounds that fuel secondary production by heterotrophic bacteria. Here we show that an abundant marine cyanobacterium, Synechococcus elongatus, contributes a variety of nitrogen-rich and sulfur-containing compounds to dissolved organic matter. A combinati...

MetabolomicsDissolved organic carbon compounds in deep-sea hydrothermal vent fluids from the East Pacific Rise at 9°50′N

Deep-sea hydrothermal vents are unique ecosystems that may release chemically distinct dissolved organic matter to the deep ocean. Here, we describe the composition and concentrations of polar dissolved organic compounds observed in low and high temperature hydrothermal vent fluids at 9°50′N on t...

MetabolomicsSponge exhalent seawater contains a unique chemical profile of dissolved organic matter
Sponges are efficient filter feeders, removing significant portions of particulate and dissolved organic matter (POM, DOM) from the water column. While the assimilation and respiration of POM and DOM by sponges and their abundant microbial symbiont communities have received much attention, there is ...

MetabolomicsEvidence for quorum sensing and differential metabolite production by Ruegeria pomeroyi in response to DMSP
Microbial alteration and remineralization of organic matter in the ocean play essential roles in the carbon cycle. The impact of individual compounds as either growth substrates or infochemicals is still poorly constrained in models, particularly for organisms with relatively versatile genomes. Here...

MetabolomicsMetabolites from surface seawater collected in Narragansett Bay
In aquatic environments, the production and consumption of organic compounds is directly tied to the metabolic potential of the in situ microbial community. The community’s metabolic potential can be assessed using metatranscriptomics, which is a measure of gene expression in the environment. More r...

MetabolomicsPhosphorus availability regulates intracellular nucleotides in marine eukaryotic phytoplankton
Phosphorus limitation is pervasive in the oligotrophic surface ocean and marine microorganisms use different strategies to survive, and thrive, at these low nutrient levels. Eukaryotic algae such as diatoms are extremely sensitive to phosphorus limitation and recent transcriptomics work has suggeste...

MetabolomicsIntracellular metabolites from an experimental manipulation of marine microorganisms
The marine environment holds one of the largest pools of reduced organic carbon on Earth. Within this organic carbon are metabolites produced as a result of microbial activity. This project considers the effects of predation and viral lysis on the metabolites found in the surface ocean. Using seawat...

MetabolomicsDissolved organic matter produced by Thalassiosira pseudonana
Phytoplankton are significant producers of dissolved organic matter (DOM) in marine ecosystems but the identity and dynamics of this DOM remain poorly constrained. Knowledge on the identity and dynamics of DOM are crucial for understanding the molecular-level reactions at the base of the global carb...
