Upland cotton sequence now publicly available

A consortium led by Z. Jeffrey Chen of The University of Texas at Austin and Jane Grimwood and Jeremy Schmutz of HudsonAlpha Institute for Biotechnology has made publicly available a significantly improved high-quality genome sequence of Upland cotton (Gossypium hirsutum). This sequence of the species making up greater than 90% of the world’s spinnable cotton fiber builds upon previous genome sequences published in the past five years.

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.
