Some scholars argue for a fairly rapid process, of a few centuries; while others argue that the process from cultivation to domestication took up to 5,000 years. This work was supported in part by the China National Science Foundation Grant Nos. Part of wheats adaptability is due to the fact that it occurs both as winter habit varieties (requiring a cold period of 6 to 8 weeks to trigger reproduction), and spring habit varieties (not requiring the cold period). Other surveys at Bouldnor Cliff identified a submerged Mesolithic site 16 meters below sea level. Wheat seeds, fragments, and pollen were not found at Bouldnor Cliff, but the DNA sequences from the sediment match Near Eastern wheat, genetically different from LBK forms.

There is much evidence that domesticated wheat was widely used in the Levant until about 10,400 years ago, but when this began is still open to debate. The sediments were laid down about 8,000 years ago, several centuries earlier than the European LBK sites. The domestication of wheat was instrumental in the transition of human behavior from hunter-gatherers to farmers.

Wheat is one of the most important grain crops in the world, and consists mainly of two types: the hexaploid bread wheat (Triticum aestivum) accounting for about 95% of world wheat production, and the tetraploid durum wheat (T. durum) accounting for the other 5%. Mol Breeding 28, 281301 (2011). The process of developing synthetic hexaploid wheat is diagrammed in Figure 3. Common wheat is a hexaploid species with three sets of similar but distinct chromosomes.

Wheat is primarily a cool season crop, but is broadly adapted to many types of growing conditions, both irrigated and rainfed, and is especially important as a staple crop in semi-arid conditions. tauschii plants, creating a so-called bottleneck effect where only a limited amount of D-genome variation became incorporated into the hexaploid crop. Synthetic hexaploids are not directly useful for wheat production because they are typically not adapted to the target growing area and they express wild species traits, such as poor threshing (i.e., the seeds do not separate easily from the enclosing glume tissue) and excessive lodging (Figure 3). 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.

Most of the 25,000 different forms of modern wheat are varieties of two broad groups, called common wheat and durum wheat. Some scientists suggest that wheat reached England by sea. tauschii is an attractive species for introgression into common wheat, because its genome readily pairs and recombines with wheats D genome chromosomes. However, advances in sequencing technologies have improved the state of genomic resources for both wheat and barley. Euphytica 100:245248, Article (2008). Want to create or adapt books like this?

Shifts in Plant Functional Strategies over the Course of Wheat Domestication, Sedimentary DNA from a Submerged Site Reveals Wheat in the British Isles 8000 Years Ago. The earliest present evidence for the utilization of wheat comes from the Ohalo II site in Israel, where the wild, brittle tetraploid wheat Triticum dicoccoides, dated as 19,000 years old, was found, suggesting the initial steps towards sedentism and cereal agriculture (Kislev et al. From a wild Asian grass to a refined crop that is the staple diet of half the world's population, the domestication of Oryza sativa spans centuries, but the grain's ancestry is hotly contested.
