Based on sequences for hundreds of E. coli ST131 lineage isolates, researchers propose a model that involves negative frequency-dependent selection on accessory parts of the genome.

Using meat and clinical samples collected prospectively over a year, researchers found evidence for poultry-to-human transmission of Escherichia coli sequence type 131.

Brown bear.

By sequencing four ancient cave bears and comparing them to other bear species, researchers retraced historical admixture of cave bears and brown bears.

Diet- and height-related variants were selected for in a Flores Island pygmy population, according to a study, which also provided insights into the population's history.

When researchers sequenced some 800 global Staphylococcus aureus isolates, they saw signs of previous jumps from humans to domestic animals and beyond.

Using genome sequencing and phylogenetics, researchers have shown that the industrial yeast Pichia kudriavzevii is genetically the same species as Candida krusei.

Starting with an 800-year-old sample from Norway, researchers retraced relationships between pig- and human-infecting Salmonella enterica lineages.

Deepwater rice in the Philippines.

A search for genetic contributors to flood-tolerant rice led to a distinct version of the gibberellin biosynthesis gene SD1.

Using bulk DNA samples produced from more than 5,000 subfossil bone fragments, researchers retraced species trajectories and extinctions over time in New Zealand.

Goat kid.

Researchers sequenced mitochondrial and/or nuclear genomes for dozens of wild and domestic ancient goats to explore domestication and selection patterns.
