Wild wheat shatters and falls to the ground to reseed itself when ripe, but domesticated wheat stays on the stem for easier harvesting. The combination of the A, B, and D genomes led to common bread wheat, which has all three genomes. A separate lineage of the A genome led to domesticated einkorn wheat (Triticum monococcum ssp.

Also, todays wheat varieties have a shallower root system with a large portion of fine roots, so the biomass grows above ground rather than underground. But other experiments led by evolutionary geneticist Robin Allaby and originally published in Watson (2018) suggest that ancient DNA from submarine sediments is less degraded than in other environments. Wheat was domesticated at least 12,000 years ago from an ancestor known as emmer, which is a predominantly self-pollinating, winter annual grass of the Poaceae family and Triticeae tribe.

Both crops are characterized by large, complex genomes which were long thought to be beyond the scope of whole-genome sequencing. The domestication phase thus spread over several centuries and simultaneously concerned several species: einkorn ( Triticum monococcum ), emmer wheat ( T. dicoccum ), barley ( Hordeum vulgare) and rye ( Secale cereale) [13], [15].
