Stanford, CA— Plant genetic diversity in Central Europe could collapse due to temperature extremes and drought brought on by climate change, according to a new paper in Nature led by Moises Exposito-Alonso, who joins Carnegie next month from the Max Planck Institute for Developmental Biology and UC Berkeley. Because only a few individuals of a species are already adapted to extreme climate conditions, the overall species genetic diversity could be greatly diminished, according to the findings.

A team of researchers from the Max Planck institute, University of Tübingen, Technical University of Madrid, and UC Berkeley who analyzed variants of the mustard plant Arabidopsis thaliana—commonly used for biological research—which were collected from more than 500 locations throughout Europe and grown in Spain and Germany under low-rainfall conditions. This revealed how individual plants responded to heat and drought.
