Gene duplication is an important evolutionary mechanism allowing to provide new genetic
material and thus opportunities to acquire new gene functions for an organism, with major …

In the ongoing debates about eukaryogenesis—the series of evolutionary events leading to
the emergence of the eukaryotic cell from prokaryotic ancestors—members of the Asgard …

Coevolution between bacteriophages (phages) and their bacterial hosts occurs through
changes in resistance and counter-resistance mechanisms. To assess phage–host …

Bacteria with two cell membranes (diderms) have evolved complex systems for protein
secretion. These systems were extensively studied in some model bacteria, but the …

Catfish represent 12% of teleost or 6.3% of all vertebrate species, and are of enormous
economic value. Here we report a high-quality reference genome sequence of channel …

Azaleas (Ericaceae) comprise one of the most diverse ornamental plants, renowned for their
cultural and economic importance. We present a chromosome-scale genome assembly for …

The ecophysiology of one candidate methanogen class WSA2 (or Arc I) remains largely
uncharacterized, despite the long history of research on Euryarchaeota methanogenesis. To …

The roles of restriction-modification (RM) systems in providing immunity against horizontal
gene transfer (HGT) and in stabilizing mobile genetic elements (MGEs) have been much …

Integrons recombine gene arrays and favor the spread of antibiotic resistance. Their broader
roles in bacterial adaptation remain mysterious, partly due to lack of computational tools. We …

The use of comparative genomics for functional, evolutionary, and epidemiological studies
requires methods to classify gene families in terms of occurrence in a given species. These …
