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...

Domestication has induced major genetic changes in crop plants to satisfy human needs and as a consequence of adaptation to agroecosystems. This adaptation might have affected root exudate composition, which can influence the interactions in the rhizosphere. Here, using two different soil types (sand, soil), we provide an original example of the impact of domestication and crop evolution on roo...

Domestication and breeding have influenced the genetic structure of plant populations due to selection for adaptation from natural habitats to agro-ecosystems. Here, we investigate the effects of selection on the contents of 51 primary kernel metabolites and their relationships in three Triticum turgidum L. subspecies (i.e., wild emmer, emmer, durum wheat) that represent the major steps of tetr...

Wheat is one of the Neolithic founder crops domesticated ~10 500 years ago. Following the domestication episode, its evolution under domestication has resulted in various genetic modifications. Grain weight, embryo weight, and the interaction between those factors were examined among domesticated durum wheat and its direct progenitor, wild emmer wheat. Experimental data show that grain weight h...

BACKGROUND "Evolution Canyon" (ECI) at Lower Nahal Oren, Mount Carmel, Israel, is an optimal natural microscale model for unraveling evolution in action highlighting the basic evolutionary processes of adaptation and speciation. A major model organism in ECI is wild emmer, Triticum dicoccoides, the progenitor of cultivated wheat, which displays dramatic interslope adaptive and speciational dive...

Abstract Triticum turgidum ssp. dicoccoides (wild emmer wheat) was one of the first plants that gave rise to domestic wheat forms in southwest Asia. The details domestication and its early dispersal routes out Asia remain elusive, especially with regard east. In this study, we combine whole genome data from a selection specimens modern wild T. dicoccum (emmer wheats) previously published 3,000 ...

(2014): Composition, protein contents, and microstructural characterisation of grains and flours of emmer wheats (Triticum turgidum ssp. dicoccum) of the central Italy type. Czech J. Food Sci., 32: 115–121. The microstructural characteristics were evaluated of two types of Italian Farro (Triticum turgidum ssp. dicoccum) ...

A study was designed to sample and characterize 12 populations of wild emmer wheat in Jordan at the high-molecular-weight (HMW) glutenin and allozyme levels. Data were collected and individual plants were sampled from 207 permanent sampling points in three central, three peripheral, and six marginal populations during all or part of a five-year study period. Patterns of variation, based on four...

Emmer wheat, Triticum dicoccum SCHUEBL, is an old variety of cereals which has been traditionally grown in aride areas. Nowdays, it is mainly grown in Italy, Spain, Turkey, Austria and in the Czech republic. This article deals with a study of quality parametres and selected economic parametres of 6 varieties coming from the genetic resources of emmer wheat. High crude protein content in grain w...
