The paper develops a maximum-likelihood framework to estimate gene prevalence from incomplete genomes and applies it to Prochlorococcus, revealing a pangenome dominated by rare genes.

The paper identifies genetic traits of low-light adapted Prochlorococcus in the Equatorial Pacific, showing loss of nitrite assimilation and use of an iron-independent HemG isoform.

The paper investigates how virus-grazer interactions affect Prochlorococcus mortality, virus production, and organic matter aggregation in a simplified marine ecosystem.

This study shows how the growth phase of a diatom affects the algicidal activity of a bacterial strain and reveals gene expression shifts in the bacteria in response to host state and environmental cues.

The paper identifies key picophytoplankton and co-occurring mixotrophs linked to biogeochemical dynamics in the North Pacific Transition Zone using molecular and biogeochemical data.

A newly isolated bacterium from the Pacific Ocean kills diatoms, suggesting a pathogenic role in open-ocean ecosystems.

The paper introduces GRUMP, a database of global ocean microbial communities using universal primers, enabling direct comparison of taxonomic ratios across samples and domains.

The paper develops a sparse tensor decomposition method to analyze metatranscriptomes and identifies gene expression changes in marine cyanobacteria under nitrogen and iron scarcity.

The paper constructs a genome-scale metabolic model of Thalassiosira pseudonana to show how nitrogen and sulfur metabolism help balance redox states and influence organic matter secretion.

The paper identifies a plastid antiporter in Thalassiosira pseudonana that shows differential transcript levels under elevated CO2, suggesting it could serve as a bioindicator of diatom resilience.
