Draft genome of the wheat A-genome progenitor Triticum urartu [PDF]
Nature, 2013 Bread wheat (Triticum aestivum, AABBDD) is one of the most widely cultivated and consumed food crops in the world. However, the complex polyploid nature of its genome makes genetic and functional analyses extremely challenging. The A genome, as a basic genome of bread wheat and other polyploid wheats, for example, T. turgidum (AABB), T.

An analysis of homoeologous microsatellites from Triticum urartu and Triticum monococcum
Plant Science, 2004Compared to hexaploid common wheat (Triticum aestivum, 2n=6x=42, AABBDD), little is known about microsatellites and their nucleotide sequences in related diploid wheat species carrying the Au or Am genomes. We tried to amplify homoeologous microsatellites from Triticum urartu (2n=2x=14, AuAu) and Triticum monococcum (2n=2x=14, AmAm ) using 54 sets of ...

TRITICUM URARTU AND GENOME EVOLUTION IN THE TETRAPLOID WHEATS
American Journal of Botany, 1978The A genome of the tetraploid wheats (AABB, 2n = 28) shows 5‐6 bivalents in crosses with Triticum boeoticum (2n = 14) and various Aegilops diploids (2n = 14). The B genome has never been similarly identified with any species, and is commonly thought to have been modified at the tetraploid level.

The diploid wheats Triticum boeoticum and T. urartu are sympatric with one another throughout the geographic range of the wild tetraploids. Reciprocal crosses between ecogeographic types within each diploid species gave viable seed, but interspecific crosses consistently gave viable seed only when T. boeoticum was the female parent.

Diversity and distribution of Rc1 alleles in Triticum urartu from the Middle East
Genetic Resources and Crop Evolution, 2017Rc1 (red coleoptile) encode a R2R3-MYB transcription factor TaMYB-A1 in common wheat, but the homologous genes have not been reported in Triticum urartu or Triticum monococcum, both species being sources of the ancient A genome. In this study, four alleles were discovered in 120 T. urartu accessions, and two alleles from nine T.

To gain a better understanding of cold acclimation process in wheat, we applied a 2-DE based proteomic approach to discover changes in proteome profile of a diploid wild wheat (Triticum urartu L.) during prolonged cold stress treatment. To this end, plants were grown in pots and the growing seedlings (4-leaf stage) were exposed to cold stress.

Reassessing domestication events in the Near East: Einkorn and Triticum urartu
Genome, 2008To reassess domestication events in the Near East, accessions of Triticum urartu from a well-described sampling were combined with a representative sample covering the Karacadağ Einkorn wheat domestication. The observed DNA separation between the two wheat species accounts for the main differentiation, but geographic variation within T.

A PCR system was designed to amplify 5S spacer rDNA specifically from homeologous chromosome 1 in a variety of species representative of the Aegilops and Triticum genera. Two polymerase chain reaction (PCR) primer combinations were used, one of which appears to be apomorphic in nature and specific to chromosome 1A in Triticum urartu and tetraploid and ...

The origin of polyploid wheat genomes has been the subject of numerous studies and is the key problem in wheat phylogeny. Different diploid species have been supposed to donate genomes to tetraploid and hexaploid wheat species. To shed light on phylogenetic relationships between the presumable A genome donors and hexaploid wheat species we have applied
