Figure 1From: The evolutionary history of the Arabidopsis lyrata complex: a hybrid in the amphi-Beringian area closes a large distribution gap and builds up a genetic barrierDistribution of Arabidopsis accessions investigated. Accessions of the Arabidopsis lyrata complex were analysed for nuclear ITS and PgiC regions, and cpDNA trnL/F. Accessions of the Arabidopsis halleri complex were analysed for PgiC only. Maximal glaciation of the LGM is drawn according to Ehlers and Gibbard [56].Back to article page
