domestication of wheat

Mol Biol Evol 23:13861396, Dvorak J, Luo MC, Akhunov ED (2011) N.I. Modern wheat cultivars also have a shallower root system, with a larger proportion of fine roots, investing biomass above rather than below ground. DNA analysis of wheat and its wild relatives led Marcussen et al. Evolving from an ancestral plant called emmer that still exists today, domestication of wheat was at least 12,000 years ago. Available from https://colostate.pressbooks.pub/cropwildrelatives/chapter/wheat-breeding-with-crop-wild-relatives/. One of the ongoing arguments about wheat is the length of time it took for the domestication process to complete. Plant Breed 115:407409, Watanabe N (2005) The occurrence and inheritance of a brittle rachis phenotype in Italian durum wheat cultivars. One possible way that might have occurred is that farmers harvested wheat after it was ripe, but before it self-dispersed, thereby collecting only the wheat that was still attached to the plant. eCollection 2022. Would you like email updates of new search results? However, advances in sequencing technologies have improved the state of genomic resources for both wheat and barley. eCollection 2021 Jun. dicoccoides, or T. dicocoides) is a plant of the genus Triticeae and the genus Triticeae, generally self-pollinating, grown in winter and harvested in summer. The purpose of this chapter is to explain how wheat originated in the Fertile Crescent of the Middle East, and how knowledge of wheats ancestors informs strategies for continued improvement of the cultivated crop.

Dr. Patrick Byrne shows examples of the A, B, and D genome ancestors of wheat, describing wheats evolutionary history, and explaining how wild wheats are relevant to modern wheat breeding. A creative strategy for addressing the impoverished D genome diversity of common wheat is the development of synthetic hexaploid wheats (McFadden and Sears, 1946; Trethowan and Mujeeb-Kazi, 2008; Ogbonnaya et al., 2013).

Development of synthetic hexaploid wheat (Ogbonnaya et al., 2013). The domestication of wheat ( Triticum aestivum L.) from wild grasses in the Middle East is a fascinating story that resulted in one of the world's most important and widespread crops. About 10,000 years ago, T. aestivumderived from a cross between domesticated emmer (Triticum dicoccum) and the goat grass Aegilops tauschii. 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.

Science 278:13121314, Hillman G, Davies S (1990) Measured domestication rates in wild wheats and barley under primitive cultivation, and their archaeological implications. 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. The origins of our modern wheat, according to genetics and archaeological studies, are found in the Karacadag mountain region of what is today southeastern Turkeyemmer and einkorn wheats are two of the classic eight founder crops of the origins of agriculture.

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.

In domesticated wheat this dispersal mechanism has been lost; the ear remains entire even after ripening, making it easier for the grains to be gathered. This hybridization is believed to have occurred only 8000 to 10,000 years ago, most likely in an area south of the Caspian Sea in present-day Iran (Gepts, 2018).
