Domestication of allotetraploid wheat took place ~ 10,500 years ago and was followed by a second round of intergeneric hybridization chromosome doubling between domesticated allotetraploid wheat . Synthetic hexaploid lines have been shown to be useful sources of variation for abiotic and biotic stress tolerance, as well as agronomic and novel grain quality traits. 2022 Jul 29;13:898769. doi: 10.3389/fpls.2022.898769.

The evidence is abundant that by about 10,400 years ago, domesticated wheat was in widespread use throughout the Levant region; but when that started is up for debate. It was a key event in the agricultural revolution that occurred about 10,000 years ago in the Fertile Crescent of the Middle East. Scholars suggest that the wheat got to Britain by boat.

According to French botanist Agathe Roucou and colleagues, the domestication process also caused multiple changes in the plant that were generated indirectly.

Ancient forms have built-in coordination between above and below ground functioning, but the human selection of other traits has forced the plant to reconfigure and build new networks. Expert Answer.

The founder crops (or primary domesticates) are the eight plant species that were domesticated by early Neolithic farming communities in Southwest Asia and went on to form the basis of agricultural economies across much of Eurasia, including Southwest Asia, South Asia, Europe, and North Africa.They consist of three cereals (emmer wheat, einkorn wheat, and barley), four pulses (lentil, pea .

Their improved yield performance under drought stress conditions appears to be due at least in part to shifts in their rooting profile, whereby a greater proportion of root biomass is produced deeper in the profile (Lopes and Reynolds, 2011; Reynolds et al., 2008).
