Molecular Diversity and Landscape Genomics of the Crop Wild Relative Triticum urartu Across the Fertile Crescent [PDF]
Plant Journal, 2018 Modern plant breeding can benefit from the allelic variation existing in natural populations of crop wild relatives that evolved under natural selection in varying pedoclimatic conditions.

Applicability of Chromosome-Specific SSR Wheat Markers for the Introgression of Triticum urartu in Durum Wheat Breeding Programmes [PDF]
Plant Genetic Resources: Characterisation and Utilisation, 2011 Triticum urartu, the A-genome donor of tetraploid and hexaploid wheats, is a potential source of novel alleles for crop improvement. A fertile amphiploid between T. urartu (2n=2x=14; AuAu) and durum wheat cv 'Yavaros' (Triticum turgidum ssp. durum; 2n=4x=

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.

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.

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

Expansins are ancient proteins involved in cell wall loosening during diverse biological processes in plants. They may participate inplant developmental processes and in responses to multiple external stresses. Triticum urartu is a diploid wheat, which is the A genome donor in hexaploid wheat (AABBDD). Wheat is an important agricultural crop.
