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...

MetabolomicsCharacterization of Phytoplankton-Excreted Metabolites Mediating Carbon Flux through the Surface Ocean

The marine labile dissolved organic carbon (DOC) pool is a dynamic reservoir of thousands of molecules. After excretion or release by phytoplankton and other microbes, metabolites are rapidly consumed, resulting in very low standing concentrations (picomolar to low nanomolar). To date, marine phy...

MetabolomicsFirst evidence of sexual reproduction in a widespread protist parasite infecting marine dinoflagellates
While most parasites primarily reproduce asexually, they can transition to sexual reproduction to promote genetic diversity and maintain their infectiousness. Nonetheless, documentation of sexual reproduction is seldom observed in most parasitic species. In this study, we demonstrate the existence o...

MetabolomicsStrain level differences in marine microbial parasite-host metabolites and host mortality dynamics

Parasitism is a widespread source of mortality among marine microbial communities, with members of the diverse alveolate group Syndiniales being most prevalent and frequently identified in global omics studies. Despite their ubiquity, not much is known about Syndiniales parasite-host infection dy...

MetabolomicsChemotaxis shapes the microscale organization of the ocean’s microbiome

The capacity of planktonic marine microorganisms to actively seek out and exploit microscale chemical hotspots has been widely theorized to affect ocean-basin scale biogeochemistry, but has never been examined comprehensively in situ among natural microbial communities. Here, using a field-based ...

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...

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...

ProteomicsUnveiling Seasonal Adaptive Molecular Mechanisms in Marine Phytoplankton during Diel Cycles through Multiomics Integration
Earth tilted rotation and translation around the Sun produce one of the most pervasive rhythms on our planet, giving rise to seasonal variations in diel cycles. Although marine phytoplankton plays a key role on ecosystems, multiomics analysis of its response to these periodic environmental signals r...

ProteomicsZinc-iron co-limitation of natural marine phytoplankton assemblages in coastal Antarctica
As an essential micronutrient that is scarce in surface ocean waters, zinc (Zn) has the potential to limit oceanic photosynthetic productivity and influence the global carbon cycle. Here we observed Zn co-limitation with iron (Fe) in the natural phytoplankton community of Terra Nova Bay, Antarctica,...
