How Plants Maintain a Low-Sodium Diet Without Advice from Their Doctors

Salt tolerance is a critical stress response in many plants and is controlled by a wide variety of interacting genes. Researchers studying sodium transporters in trees from high-salinity environments have characterized the evolution of these genes and determined that they are under strong positive selection in salty soils.

Evolutionary History of a Widespread, Recently Diverged Antioxidant Enzyme in a Pig Pathogen

Peroxiredoxins are proteins conserved across all domains of life that protect cells against the threat of reactive oxygen species. Researchers have recently characterized the evolutionary history of an essential peroxiredoxin gene from a common livestock pathogen.
