Extensive transfer of genes for edible seaweed digestion from marine to human gut bacteria

The paper shows gut bacteria have extensively adapted to digest seaweed polysaccharides through gene transfer from marine bacteria, revealing widespread metabolic plasticity in the human gut microbiome.

Metabolic differences between symbiont subpopulations in the deep-sea tubeworm Riftia pachyptila

The paper identifies metabolic differences between symbiont subpopulations in Riftia pachyptila, showing small symbionts focus on division and host interaction while large ones specialize in carbon fixation and biosynthesis.

Anaerobic sulfur oxidation underlies adaptation of a chemosynthetic symbiont to oxic-anoxic interfaces

This study investigates how oxygen affects the physiology and metabolism of Candidatus Thiosymbion oneisti, an ectosymbiont of marine nematodes, revealing that sulfur oxidation genes are upregulated under anoxia.

A robust metaproteomics pipeline for a holistic taxonomic and functional characterization of microbial communities from marine particles

This paper develops a robust metaproteomics pipeline for analyzing marine particle-associated bacteria, identifying over 5,000 protein groups and revealing functional differences between free-living and particle-associated communities.

Characterization of a thaumarchaeal symbiont that drives incomplete nitrification in the tropical sponge Ianthella basta

This paper characterizes a thaumarchaeal symbiont in the sponge Ianthella basta, showing it is the sole ammonia-oxidizer and reveals adaptations for a mixotrophic lifestyle.
