The paper identifies genomic features of domoic acid biosynthesis in Pseudo-nitzschia diatoms, revealing expanded toxigenic diversity and environmental expression patterns.

The paper investigates how marine diatoms adapt to heat stress through proteomics analysis, finding that high-temperature-tolerant populations use a conservative cellular strategy under thermal stress but fail to adapt under low nitrate conditions.

The paper uses microbial and small plankton communities to predict baleen whale densities in the Southern California Current Ecosystem, finding strong predictive relationships with up to 99% variability explained.

The paper describes phytoplankton community composition in the oligotrophic Argo Basin during austral summer 2022, highlighting taxonomic and functional diversity across different depth layers.

This study identifies an expanded domoic acid biosynthesis gene cluster in Nitzschia navis-varingica through genome sequencing and biochemical validation, revealing its unique organization and evolutionary significance.

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.

The paper identifies cathepsin X as a conserved cell death protein in algae involved in responses to environmental stress through transcriptome analysis and mutant studies.

The paper investigates phosphatase activity and gene expression in the California Current Ecosystem, finding atypical phosphatases drive DOP utilization despite Pi repletion.

The paper uses genomic and hydrographic data to show that ocean circulation structures microbial diversity and function in the South Pacific.

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.

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

This study identifies sugar transporter remodeling in a symbiotic microalga, revealing how metabolic exchange is reprogrammed during photosymbiosis with a planktonic host.

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.

The paper introduces a web-based tool for collaborative analysis of mass spectrometry data, enabling remote inspection, visualization, and analysis of private and public datasets.

The paper integrates transcriptome data to annotate the Phaeodactylum tricornutum genome, identifies novel genes and alternative splicing, and explores the evolutionary origins of diatoms.

The paper identifies diatom centromeres and shows that non-native DNA sequences can function as centromeres, suggesting a mechanism for foreign DNA acquisition.
