BioSciences Seminar Series - Professor Johanna Schmitt - The genomic basis of adaptation to climate in Arabidopsis thaliana

Whether and how natural populations will adapt fast enough to persist in the face of rapid climate change is a critical question for 21st century evolutionary biology. The annual plant Arabidopsis thaliana provides a model system for investigating and predicting patterns of climate adaptation. Extensive genomic data exist from many accessions collected across the species’ climate range. These data can be combined with phenotypic data from common garden experiments using genome-wide association (GWA) to identify traits and loci associated with life history variation and fitness, and to test for a geographic signature of adaptation to climate in the site of origin. Genomic variation in seed traits controlling dormancy determines a plant's seasonal environment, and is therefore critical for climate adaptation.
