Delta-5 elongase knockout reduces DHA and TAG synthesis coupled with an increase of heat sensitivity in a marine diatom

This study shows that knocking out delta-5 elongase in a marine diatom reduces DHA and TAG synthesis and increases heat sensitivity.

Zinc stimulation of phytoplankton in a low carbon dioxide, coastal Antarctic environment: evidence for the Zn hypothesis

This study shows zinc limitation of phytoplankton in Antarctic waters, demonstrating its role in regulating net primary production and providing evidence for the Zn hypothesis.

Molecular Forecasting of Domoic Acid during a Pervasive Toxic Diatom Bloom

The paper identifies molecular predictors of domoic acid production during a harmful algal bloom and links iron and silica co-limitation to bloom dynamics and toxicity.

High Resolution Biological and Physical Sampling Reveals Expression of Domoic Acid Biosynthetic Genes at Frontal Zones

This study combines high-resolution physical and multi-omic sampling to identify DA biosynthetic gene expression in frontal zones of Monterey Bay during declining upwelling.

Host and Water Microbiota are Differentially Linked to Potential Human Pathogen Accumulation in Oysters

This study links microbial communities in water and oysters to the accumulation of potential human pathogens, finding that specific microbial taxa in oysters and water are associated with increased Vibrio parahaemolyticus.

Proteomic traits vary across taxa in a coastal Antarctic phytoplankton bloom

The paper quantifies proteomic traits across Antarctic phytoplankton taxa using metaproteomics, showing distinct clusters linked to ecological strategies and regulatory cost differences.

Proximity proteomics in a marine diatom reveals a putative cell surface-to-chloroplast iron trafficking pathway

The paper uses proximity proteomics to identify proteins associated with phytotransferrin in a marine diatom, suggesting a potential iron trafficking pathway from the cell surface to the chloroplast.

The Phaeodactylum tricornutum Diaminopimelate Decarboxylase was Acquired via Horizontal Gene Transfer from Bacteria and Displays Substrate Promiscuity

This paper identifies a horizontally transferred DAPDC gene in Phaeodactylum tricornutum that exhibits substrate promiscuity in lysine biosynthesis.

Colwellia and Marinobacter metapangenomes reveal species-specific responses to oil and dispersant exposure in deepsea microbial communities

The paper examines how dispersants affect microbial communities in oil spills by analyzing metapangenomes of Colwellia and Marinobacter, showing species-specific metabolic responses to oil and dispersant exposure.

Proteomic analysis of metabolic pathways supports chloroplast-mitochondria cross-talk in a Cu-limited diatom

The paper identifies differentially expressed proteins in diatoms under Cu limitation, revealing chloroplast-mitochondria cross-talk through isoenzyme regulation and metabolic pathway integration.

Molecular underpinnings and biogeochemical consequences of enhanced diatom growth in a warming Southern Ocean

This study examines how temperature and iron affect diatom growth and nutrient uptake in the Southern Ocean, finding that Pseudo-nitzschia thrives under warming conditions with fewer iron resources.

A high dimensional quantification of mouse defensive behaviours reveals enhanced diversity and stimulus specificity

The paper quantifies mouse defensive behaviours in high dimensions, revealing stimulus-specific diversity beyond locomotion data.
