Metagenomics literally means “beyond the genome.” Marine microbial metagenomic
databases presently comprise∼ 400 billion base pairs of DNA, only∼ 3% of that found in 1 …

Metagenomics approaches represent an important way to acquire information on the
microbial communities present in complex environments like soil. However, to what extent …

The FUT2 (Secretor) gene is responsible for the presence of ABO histo-blood group
antigens on the gastrointestinal mucosa and in bodily secretions. Individuals lacking a …

Functional metagenomics is a powerful experimental approach for studying gene function,
starting from the extracted DNA of mixed microbial populations. A functional approach relies …

Aquatic environments harbour large and diverse microbial populations that ensure their
functioning and sustainability. In the current context of global change, characterizing …

The human gut microbiome is a complex ecosystem composed mainly of uncultured
bacteria. It plays an essential role in the catabolism of dietary fibers, the part of plant material …

Background Microbial life dominates the earth, but many species are difficult or even
impossible to study under laboratory conditions. Sequencing DNA directly from the …

As part of an ongoing survey of microbial community gene expression in the ocean, we
sequenced and compared∼ 38 Mbp of community transcriptomes and∼ 157 Mbp of …

Viruses have global impact through mortality, nutrient cycling and horizontal gene transfer,
yet their study is limited by complex methodologies with little validation. Here, we use …

Alteromonas species are globally distributed copiotrophic bacteria in marine habitats.
Among these, sea-tidal flats are distinctive: undergoing seasonal temperature and oxygen …
