domestication of wheat

One of the ongoing arguments about wheat is the length of time it took for the domestication process to complete. 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.

In this review, we summarize and discuss research on wheat domestication, mainly focusing on recent findings in genetics and genomics studies. Common or bread wheat Triticum aestivum accounts for some 95 percent of all the consumed wheat in the world today; the other five percent is made up of durum or hard wheat T. turgidum ssp.

The availability of reference genomes for wheat and some of its progenitors, as well as for barley, sets the stage for answering unresolved questions in domestication genomics of wheat and barley. It grows in sporadic and semi-isolated patches and does best in regions with long, hot dry summers and short mild, wet winters with fluctuating rainfall. Mol Biol Evol 24:15061517, Hedden P (2003) The genes of the green revolution. 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).

Spelled (T. spelta) and Timopheev wheat (T. timopheevii) evolved from emmer wheats up until the Late Neolithic period, but have few buyers today. The earliest evidence for both domesticated einkorn and emmer wheat found to date was at the Syrian site of Abu Hureyra, in occupation layers dated to the Late Epi-paleolithic period, the beginning of the Younger Dryas, ca 13,00012,000 cal BP; some scholars have argued, however, that the evidence does not show deliberate cultivation at this time, although it does indicate a broadening of the diet base to include a reliance on wild grains including the wheat.

The earliest cultivated emmer has been found in the southern Levant (Netiv Hagdud, Tell Aswad, other Pre-Pottery Neolithic A sites); while einkorn is found in the northern Levant (Abu Hureyra, Mureybet, Jerf el Ahmar, Gbekli Tepe). Molecular markers were initially used to calculate distance (relatedness), genetic diversity and to generate genetic maps which were useful in cloning major domestication genes. 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). Synthetic hexaploids: Harnessing species of the primary gene pool for wheat improvement. dicoccum), which gave rise to durum or pasta wheat (Triticum turgidum ssp. Photo credit: Pat Byrne. Transitions of forms. The origins of our modern wheat can be found in the Karacadag mountain region of what is now southeastern Turkey. These chromosome sets are designated the A, B, and D genomes, each with seven pairs of chromosomes. The effect of domestication on awns in wheat does not match the clear differences between wild and domestic gene pools for other traits. 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. Emmer can grow in a variety of habitats from 100 meters below sea level to 1,700 meters above sea level, and can survive in places with annual precipitation of 200-1,300 mm.
