Metagenomics is the study of the metagenome—the collective genome of microorganisms from an environmental sample—to provide information on the microbial diversity and ecology of a specific environment. Shotgun metagenomics refers to the approach of shearing DNA extracted from the environmental sample and sequencing the small fragments.
Microbial migration profoundly impacts ecosystems. Here, the authors introduce a statistical approach to explore microbial dispersion following fecal microbiota transplant, uncovering dependencies between colonizing taxa, with insights into community dynamics.
Genome-wide association analysis in over one million individuals of European ancestry identifies 2,103 independent genetic signals (including 113 new loci) associated with blood pressure traits.
Multidisciplinary culture-dependent and -independent techniques elucidate the unique microbial nitrogen cycle in nutrient-poor coastal Antarctica soils and reveal the contribution of novel key microbes to their nitrogen budget.
Metatranscriptomic data from more than 2,000 mosquitoes of 81 species show that the composition of mosquito viral communities is determined more by host phylogeny than by climate and land-use factors, which will help to inform arbovirus surveillance.
This Genome Watch highlights different tools and strategies used to enhance the quality of metagenome-assembled genomes (MAGs) generated in microbiome studies.
An experiment that simulates rainfall events in dry soils reveals that virus members of the soil microbiome maintain the turnover of prokaryotic host communities through a ‘cull-the-winner’ model.
