Summary of main research topics

Natural variation and evolution of plants
Earth is home to over 270,000 known species of plants. This diversity of plants has been shaped mainly through adaptive evolution to various environments, including abiotic as well as biotic ones. We are interested in understanding the global plants’ diversity. We specifically examine mechanisms of adaptive evolution that proceed in natural populations of plants. In addition to such basic research on natural history, we preserve and distribute wild plant seed resources.
