Adaptation is a fundamental evolutionary process that allows species and populations to cope with changing environments. However, how adaptation operates in natural populations at the level of individual genes and their non-coding DNA environment — the genome? Using genome resequencing of natural Arabidopsis populations coupled with transcriptomics, metabolomics and field and chamber experiments, we aim to uncover how plant genomes respond to a dramatic environmental challenge – the colonization of alpine habitats after the end of ice ages. Multiple pairs of independently adapted populations provide natural replicates that will allow us to find the general trends in the process of natural selection and adaptation. Identification of candidate genes under selection in a plant model genus may also provide important clues for crop breeding aimed at tolerance to environmental challenges.
