Wild emmer genome architecture and diversity elucidate wheat evolution and domestication.
Wheat (Triticum spp.) is one of the founder crops that likely drove the Neolithic transition to sedentary agrarian societies in the Fertile Crescent more than 10,000 years ago. Identifying genetic modifications underlying wheat's domestication requires knowledge about the genome of its allo-tetraploid progenitor, wild emmer (T. turgidum ssp. dicoccoides). We report a 10.1-gigabase assembly of t...
متن کاملImpact of domestication on the phenotypic architecture of durum wheat under contrasting nitrogen fertilization.
The process of domestication has led to dramatic morphological and physiological changes in crop species due to adaptation to cultivation and to the needs of farmers. To investigate the phenotypic architecture of shoot- and root-related traits and quantify the impact of primary and secondary domestication, we examined a collection of 36 wheat genotypes under optimal and nitrogen-starvation cond...
متن کاملTetraploid Wheat Landraces in the Mediterranean Basin: Taxonomy, Evolution and Genetic Diversity
The geographic distribution of genetic diversity and the population structure of tetraploid wheat landraces in the Mediterranean basin has received relatively little attention. This is complicated by the lack of consensus concerning the taxonomy of tetraploid wheats and by unresolved questions regarding the domestication and spread of naked wheats. These knowledge gaps hinder crop diversity con...
متن کاملWild emmer wheat, Triticum dicoccoides, occupies a pivotal position in wheat domestication process
Domestication of plants and animals is the major factor underlying human civilization. Cultivated wheats refer mainly to 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%. T. aestivum derived from a cross between domesticated emmer T. dicoccum and the goat grass Aegil...
متن کاملRFLP analysis of nuclear DNA for study of phylogeny and domestication of tetraploid wheat
To study the phylogeny and domestication of tetraploid wheat species, variations in nuclear DNA of the cultivated and wild species were investigated by RFLP analysis. Twenty-two accessions representing 11 species of cultivated tetraploid wheat (Emmer wheat and Timopheevi wheat), 16 accessions of wild Emmer wheat (Triticum dicoccoides Körn.), 14 accessions of wild Timopheevi wheat (T. araraticum...
