Data for: Einkorn genomics sheds light on history of the oldest domesticated wheat

Einkorn (Triticum monococcum) is the first domesticated wheat species,
being central to the birth of agriculture and the Neolithic Revolution in
the Fertile Crescent ~10,000 years ago. Here, we generate and
analyze 5.2-gigabase genome assemblies for wild and domesticated einkorn,
including completely assembled centromeres. Einkorn centromeres are highly
dynamic, showing evidence of ancient and recent centromere shifts caused
by structural rearrangements. Whole-genome sequencing of a diversity panel
uncovered the population structure and evolutionary history of einkorn,
revealing complex patterns of hybridizations and introgressions following
the dispersal of domesticated einkorn from the Fertile Crescent. We also
discovered that around 1% of the modern bread wheat (Triticum aestivum) A
subgenome originates from einkorn. These resources and findings highlight
the history of einkorn evolution and provide a basis to accelerate the
genomics-assisted improvement of einkorn and bread wheat.
