Genome-wide FST and ω for Each Chromosome, Related to Figure 5
(A) Distribution of maximum FST scores in 10-kb windows. The centromere is shaded in each figure, and the locations of NB-LRR genes (“resistance” or R genes) are shown in red.
(B) Distribution of ω-statistic in 10-kb windows. Labels as in A. On each chromosome, the lowest genome-wide FST values, and largest estimates of the ω-statistic, are near the centromeres, which suggests that selective sweeps or background selection are common in these regions of the genome.
