Arabidopsis halleri subsp. halleri strain:Wild plants Genome sequencing
We examined genome-wide patterns of nucleotide variation in natural populations of the outcrossing herb Arabidopsis halleri and associations with climatic variation among populations in the Alps. Using a pooled population sequencing (Pool-Seq) approach, we discovered more than two million SNPs in five natural populations and identified highly differentiated genomic regions and SNPs using FST–based analyses. We tested only the most strongly differentiated SNPs for associations with a non-redundant set of environmental factors using partial Mantel tests to identify topo-climatic factors that may underlie the observed footprints of selection.
