domestication of wheat

Funct Integr Genomics 6:300–309, Liu Y-G, Tsunewaki K (1991) Restriction fragment length polymorphism (RFLP) analysis in wheat. Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. Genome evolution and modification. This change was possible because of a random mutation in the wild populations at the beginning of wheat's cultivation . The domestication of wild emmer wheat led to the selection of modern durum wheat, grown mainly for pasta production. (2007). Methuen and Go. Shifting the life cycle of grain crops from annual to perennial would usher in a new era of agriculture that is more environmentally friendly, … Jpn J Bot 19:175–229, Watanabe N, Ikebata N (2000) The effects of homoeologous group 3 chromosomes on grain colour dependent seed dormancy and brittle rachis in tetraploid wheat. Mechanisms for chromosome evolution. Enter multiple addresses on separate lines or separate them with commas. 2011). Bull Plant Industry, US Dept Agriculture, Washington, DC No. One of the ongoing arguments about wheat is the length of time it took for the domestication process to complete. The domestication of wheat around 10,000 years ago marked a dramatic turn in the development and evolution of human civiliza-tion, as it enabled the transition from a hunter-gatherer and nomadic pastoral society to a more sedentary agrarian one. Science 316:1862–1866, Dvorak J, Zhang HB (1990) Variation in repeated nucleotide sequences sheds light on the phylogeny of the wheat B and G genomes. Transitions of forms with natural seed dispersal mechanisms to forms with non-brittle rachises led to the domestication of diploid einkorn and tetraploid emmer wheat in southeast Turkey. Not logged in Here, I review historical and recent findings that have shaped our current understanding of wheat domestication. Furthermore, the domestication of wheat in South West Nigeria under rainfed agriculture in the second cropping season (July–Nov) has reduced significantly the cost of irrigation as being practiced in the Northern region of Nigeria, drier parts of Asian countries (Iran, Iraq, Syria etc) and African countries. Although domestication of plants and crops cultivated for consumption has been carried on for 11,000 years, this figure pales in comparison with the seven million years humans fed themselves by hunting wild animals and eating wild plants.

Willd. These studies, while fruitful, were inherently limited due to the limited number of available markers and the full representation of the genomes of these crops. Domestication of wheat According to the history of wheat evolution described above, only wild einkorn and wild emmer wheats were subjected to domestication selection. Its breeding has followed millennia of cultivation, sometimes with unintended selection on adaptive traits, and later by applying intentional but empirical selective pressures.

Wheat has not dramaticly changed its DNA status for over 10,000 years.

The domestication of wheat around 10,000 years ago marked a dramatic turn in the development and evolution of human civilization, as it enabled the transition from a hunter-gatherer and nomadic pastoral society to a more sedentary agrarian one. The domestication of wheat was instrumental in the transition of human behavior from hunter-gatherers to farmers. pp 439-464 | Hexaploid wheat (AABBDD, Triticum aestivum ) has undergone two separate allopolyploidization events, providing an ideal model for … Theor Appl Genet 53:209–217, Jaaska V (1980) Electrophoretic survey of seedling esterases in wheats in relation to their phylogeny. Wild wheat shatters and falls to the ground to reseed itself when ripe, but domesticated wheat stays on the stem for easier harvesting. Origin, domestication, and evolution of wheat. ), rice (Oryza sativa L.), and maize (Zea mays L.), are the major food crops for all humans and are the principal resources that have led to the emergence of human civilization as we know it today. Dawei Sun has just finished his PhD in Emma Rawlins’ lab at The Gurdon Institute. Domestication of these crops from their wild ancestors required the evolution of traits useful to humans … Probrably the longest time for DNA to stay the same; although there is a fairly close substance to modern day wheat called einborn wheat. CIMMMYT, Mexico, Dubcovsky J, Dvorak J (2007) Genome plasticity a key factor in the success of polyploid wheat under domestication. Alternative splicing (AS) occurs extensively in eukaryotes as an important mechanism for regulating transcriptome complexity and proteome diversity, but variation in the AS landscape in response to domestication and polyploidization in crops is unclear. It is known that AP2 factors can be regulated by the miR172 miRNA, and that Q bears a mutation in the miR172 binding site, but how this putative regulation affects the phenotypes associated with domestication has been unclear. Theor Appl Genet 98:472–476, Kato K, Sonokawa R, Miura H, Sawada S (2003) Dwarfing effect associated with the threshability gene, Kerber ER (1964) Wheat: Reconstitution of the tetraploid component (AABB) of hexaploids. The evidence is abundant that by about 10,400 years ago, domesticated wheat was in widespread use … We show that … On the origin and phylogeny of polyploid wheats. A thorough and comprehensive understanding of wheat evolution and domestication will provide critical knowledge to the spawning of a new agricultural revolution, which will be necessary to provide sustenance for a rapidly increasing world population under global climate change. Without the transition, however, mankind could not have completed its social and cultural evolution. Allopolyploidization, mutations in genes governing threshability and other domestication related traits, and interspecific gene flow led to the formation of today’s economically important bread wheat.

At Jericho, Netiv Hagdud, and Gilgal (in the Jordan Basin), and Aswad (near Damascus), domesticated einkorn, emmer, and barley appear between 8000 and 7700 B.C. In: Moore AMT, Hillman GC, Legge AJ (eds) Village on the Euphrates. During the second UK lockdown, we met him (virtually) to hear about the trials and tribulations of his PhD, and discuss his experience of studying in the UK. Whole-genome sequence analysis, additional genetic studies, and advances in archaeology will likely address our unanswered questions in the future. Notably, domesticated varieties possess a subcompact spike and a loss of the tough glumes that protect the grain, leading to a free-threshing phenotype. ().

It was a key event in the agricultural revolution that occurred about 10,000 years ago in the Fertile Crescent of the Middle East.
