Our proposals are based on core...

The existence of a large‐scale population structure was investigated in Arabidopsis thaliana by studying patterns of polymorphism in a set of 71 European accessions. We used sequence polymorphism surveyed in 10 fragments of ∼600 nucleotides and a set of nine microsatellite markers. Population structure was investigated using a model‐based inference framework. Among the accessions studied, the presence of four groups was inferr...
