Science 143:253–255, Kerber ER, Dyck PL (1969) Inheritance in hexaploid wheat of leaf rust resistance and other characters derived from, Kerber ER, Rowland GG (1974) Origin of the free threshing character in hexaploid wheat. We show that … 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. Enter multiple addresses on separate lines or separate them with commas. Wheat was one of the first crops to be domesticated more than 10,000 years ago in the Middle East. In: Padulosi S, Hammer K, Heller J (eds) Hulled wheats, promoting the conservation and use of underutilized and neglected crops 4: proceedings of the first international workshop on hulled wheats. Landw Jahrbuch 92:241–252, Blake NK, Lehfeldt BR, Lavin M, Talbert LE (1999) Phylogenetic reconstruction based on low copy DNA sequence data in an alloploid: the B genome of wheat. Intraspecific variation in, Ozkan H, Brandolini A, Schafer-Pregl R, Salamini F (2002) AFLP analysis of a collection of tetraploid wheats indicates the origin of emmer and hard wheat domestication in Southeast Turkey. 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. Mechanisms for chromosome evolution. In domesticated wheat, grains are larger, and the seeds (inside the spikelets) remain attached to the ear by a toughened rachis during harvesting. In: Bonjean AP, Angus WJ (eds) The world wheat book. (). In the Americas, maize is called corn, somewhat confusingly for the rest of the English-speaking world, where 'corn' refers to the seeds of any grain, including barley, wheat or rye. This is a preview of subscription content, Aaronsohn A (1910) Agricultural and botanical explorations in Palestine. Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. On the origin and phylogeny of polyploid wheats. Genome 36:21–31, Dvorak J, Luo MC (2001) Evolution of free-threshing and hulled forms of, Dvorak J, Luo MC, Yang ZL, Zhang HB (1998) The structure of the, Dvorak J, Akhunov ED, Akhunov AR et al (2006) Molecular characterization of a diagnostic DNA marker for domesticated tetraploid wheat provides evidence for gene flow from wild tetraploid wheat to hexaploid wheat. Notably, domesticated varieties possess a subcompact spike and a loss of the tough glumes that protect the grain, leading to a free-threshing phenotype. The Q gene governs the free-threshing character and square spike phenotype. In: Jenkins BC (ed) Proceedings of the first international wheat genetics symposium. Cultivation of cereals played a major part in the shift from hunting and gathering to plant and animal husbandry. We are aware that the COVID-19 pandemic is having an unprecedented impact on researchers worldwide. Domestication genes of the annual grass wheat are highly conserved in the perennial intermediate wheatgrass (Thinopyrum intermedium), providing an opportunity for accelerated domestication of a perennial grain using a mutagenesis approach. Together, these two papers convincingly demonstrate that tight regulation of Q by miR172 is important for the acquisition of free-threshing character in domesticated wheat varieties, and help to resolve prior controversies as to the mechanism underlying the Q phenotype.

Genetics, genomics, and archaeobotany have together provided strong evidence and insights regarding the time, place, and events involved in the evolution and domestication of modern wheat, but numerous questions remain unanswered. pp 439-464 | 80.211.132.121. Our objective was to map domestication-related quantitative trait loci (QTL) in T. dicoccoides . Wild emmer wheat, Triticum dicoccoides , is the progenitor of modern tetraploid and hexaploid cultivated wheats. Wheat Evolution, Domestication, and Improvement Perry Gustafson, Olga Raskina, XueFeng Ma, and Eviatar Nevo INTRODUCTION Cereals, including wheat (Triticum spp. Through analysis of Q’ and induced revertants, the authors show that higher levels of AP2 activity are associated with the formation of ectopic florets in place of glumes – an apparent homeotic transformation in the spike. 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.
