Speciation in flowering mustard plant driven by alleles adapted to local conditions

HudsonAlpha faculty investigator part of team that identified chromosomal inversion

On the slopes of the Northern Rocky Mountains, the flowering mustard plant Boechera stricta is undergoing a quiet transformation – that is, evolving into a fitter species better adapted to its local environment. HudsonAlpha faculty investigator Jeremy Schmutz was part of a team led by Thomas Mitchell-Olds of Duke University who analyzed the mechanisms by which Boechera stricta living in a hybrid zone in the Northern Rocky Mountains experienced positive directional selection. Their study was published in Nature Ecology and Evolution in April 2017.
