Interactions between fungal and bacterial microbiome members alter Drosophila melanogaster's chemical environment, affecting host behavior and survival.

Bacterial-encoded covalent adhesion is a new molecular principle in host-microbe interactions and may play a key role in host colonization by a wide range of Gram-positive bacteria.

Physical and chemical interactions with bacteria influence the life and death of Emiliania huxleyi, a bloom-forming micro-alga important in global biogeochemical cycles.

A basidiomycete yeast closely related to fungal smuts is an antagonistic microbe in the Arabidopsis leaf phyllosphere that inhibits infection by Albugo laibachii via a GH25 hydrolase with lysozyme activity.

A network of the gut chemical landscape predicts microbe-mediated biotransformation of foods and drugs and supports the generation of mechanistic hypotheses of microbiome metabolic phenotypes that shape human biology.

Experiments and mathematical modelling show that rare nitrogen fixing symbionts invade a population dominated by non-fixing bacteria across plant generations, above a threshold of a combination of ecological factors.

Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.

Microbiomediversity favors further diversity in a positive feedback that is strongest in lower-diversity biomes but which plateaus as niches are increasingly filled in higher-diversity biomes.

Host characteristics drive the assembly of similar communities within the convergently evolved and geographically distant pitcher ecosystems of carnivorous pitcher plants.

In the most comprehensive survey of sourdough starter biodiversity, this work identifies processes that control the diversity and function of sourdough microbiomes at a continental scale.
