Researchers used exome sequences on almost 550 canine transmissible venereal tumors to estimate their origin, global spread, and evolution.

In PLOS this week: alternatively spliced form of FBXO38 contributes to chronic obstructive pulmonary disease, evolution of the avian influenza virus H9N2, and more.

Despite the diversity detected in Group A Streptococcus strains from more than 20 countries, investigators narrowed in on broadly shared sequences with relatively low variation.

Genomic data for almost 300 ancient Eurasian horses points to lost equine lineages, horse relationships that reflect human interactions, and a recent loss in genetic diversity.

Using genome sequence data for 429 accessions, an international team tracked chickpea's origin and spread, while identifying markers for important traits.

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.

To understand the evolution of brain conditions and other traits, investigators plan to sequence human and pathogen DNA in thousands of samples from Europe.
