Patterns of genetic differentiation and Tajima’s D in sliding genomic windows across the genome of NA-O samples. Smoothed genetic differentiation (FST) and sliding window analysis of Tajima’s D across the genome of the NA-O samples. a Smoothed genetic differentiation among three NA-O genetic structure groups estimated using loci present in at least 50% of individuals within each group. (b) 120Kbp sliding window analysis of Tajima’s D, across the genome of all NA-O samples (N = 28). Windows showing elevated (green) or reduced (magenta) FST in a region of elevated diversity are indicated in (a) and (c), with regions of elevated Tajima’s D in regions of significantly elevated diversity (green) indicated in (b) and (d). The location of 206 annotated NLR genes on the A. lyrata reference chromosomes 1–8 are denoted by blue squares, with those in the windows overlapping with regions of elevated diversity highlighted in green or magenta. A similar set of plots are given for all EU-N samples in Additional file 1: Figure S10
