Extended Data Fig. 8: Divergence of domesticated barley populations.
From: A haplotype-based evolutionary history of barley domestication
(a) Principal component analysis of 19,778 based on genotyping-by-sequencing data of Milner et al.24 (62,888 biallelic SNPs). Samples analyzed in this study are shown in non-gray color. Blue circles delineate the groups used for the comparisons in panel (b): NE – Near East; EU – Europe and Mediterranean Basin; ETH – Ethiopia; Asia – Central and East Asia; EUT – EU two-rowed; EUS – EU six-rowed. (b) Distribution of sequence divergence between populations of domesticated barley. The comparisons are indicated in blue font below the sub-panels. (c) Absolute allele frequency difference (AFD) between different domesticated barley populations in sliding windows (size: 100 kb, shift: 20 kb) along the genome. AFD was computed on the haplotype matrix of high-coverage (~10x) samples. (d) FST in sliding windows (size: 100 kb, shift: 20 kb) along the genome. FST was computed from the SNP matrix of all samples (matrix SNP2, see Methods).
