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 ...

MetabolomicsUntargeted Metabolomics Reveals a Lack Of Synergy between Nifurtimox and Eflornithine against Trypanosoma brucei
A non-targeted metabolomics-based approach is presented that enables the study of pathways in response to drug action with the aim of defining the mode of action of trypanocides. Eflornithine, a polyamine pathway inhibitor, and nifurtimox, whose mode of action involves its metabolic activation, are ...

MetabolomicsGlobal ocean lipidomes show a universal relationship between temperature and lipid unsaturation

Global-scale surveys of plankton communities using “omics” techniques have revolutionized our understanding of the ocean. Lipidomics has demonstrated the potential to add further essential insights on ocean ecosystem function but has yet to be applied on a global scale. We analyzed 930 lipid samp...

MetabolomicsRNA virus-induced metabolic reprogramming in a bloom-forming, marine diatom
• Diatoms are a widespread group of phytoplankton that disproportionately influence the global carbon cycle through substantial contributions to primary production and carbon export in the ocean. Marine viruses are major drivers of host metabolic reprogramming and mortality and it is increasingly cl...

MetabolomicsChitin utilization by marine picocyanobacteria and the evolution of a planktonic lifestyle.
Marine picocyanobacteria Prochlorococcus and Synechococcus, the most abundant photosynthetic cells in the oceans, are generally thought to have a primarily single-celled and free-living lifestyle. However, while studying the ability of picocyanobacteria to supplement photosynthetic car...

MetabolomicsOrganic sulfur: a spatially variable, labile, and understudied component of marine organic matter

Sulfur (S) is a major heteroatom in organic matter. This project evaluated spatial variability in the concentration and molecular-level composition of organic sulfur along gradients of depth and latitude. We measured the concentration of total organic sulfur (TOS) directly from whole seawater. Ou...

MetabolomicsInsights into the controls on metabolite distributions along a latitudinal transect of the western Atlantic Ocean

Metabolites, or the small organic molecules that are synthesized by cells during metabolism, comprise a complex and dynamic pool of carbon in the ocean. They are an essential form of information, linking genotype to phenotype at the individual, population and community levels of biological organi...

MetabolomicsSuboxic DOM is bioavailable to surface prokaryotes in a simulated overturn of an oxygen minimum zone, Devil’s Hole, Bermuda
Oxygen minimum zones (OMZs) are expanding due to increased sea surface temperatures, subsequent increased oxygen demand through respiration, reduced oxygen solubility, and thermal stratification driven in part by anthropogenic climate change. Devil's Hole, Bermuda is a model ecosystem to study OMZ m...

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...

MetabolomicsA metabolite roadmap of the wood-forming tissue in Populus tremula (GC-MS assay; Wood ring and extraxylary tissue)

Wood, or secondary xylem, is the product of xylogenesis, a developmental process that begins with the proliferation of cambial derivatives and ends with mature xylem fibers and vessels with lignified secondary cell walls. Fully mature xylem has undergone a series of cellular processes, including ...
