phylogenetic analysis

An international team analyzed almost 6,500 Mycobacterium tuberculosis isolates from around the world to find new and known resistance mutations.

While the virus they found appears old, the researchers found it to be closely related to modern ones, indicating that it has infected people for centuries.

By sequencing Vibrio cholerae isolates from Africa and Latin America, investigators got a look at the lineages leading to outbreaks over several decades.

With hundreds of bacterial genome sequences, researchers characterized horizontal gene transfer hotspots contributing to genome evolution and diversification.

Researchers sequenced and analyzed the genome of Apostasia shenzhenica, which is part of a small sister lineage to other plants in the Orchidaceae family, uncovering new evolutionary clues.

More than a dozen Yersinia pestis sub-populations turned up in a genome sequence and genotype analysis of strains collected across the country over 18 years.

Phylogenetic patterns for more than 2,200 dengue viruses collected in Asia over almost 60 years suggest air travel hubs have contributed to the virus' spread in the region.

The Malagasy people harbor both African and Asian ancestry, which varies with geography and gives insight into how and when Madagascar was settled.

A Svante Pääbo-led team studied the mitochondrial and nuclear genome of a Denisovan individual that lived 128,000 years to 227,000 years ago.
