A haplotype-based evolutionary history of barley domestication

Barley is an old crop with a complex history. To deeply study history of barley domestication, we pursue a haplotype-based approach to connect diversity and population structure in wild and domesticated barley. We sequenced the genomes of 628 genebank accessions and 23 archaeological specimens. Using these data, we infer the spatiotemporal origins of haplotypes and map the contributions of different wild barley populations either during the initial phase of domestication or through later gene flow. Domestication genes and ancient DNA sequences corroborate our genome-wide analysis in present-day samples.
