Assessment of genetic diversity and relationships among Triticum urartu and Triticum boeoticum populations from Iran using IRAP and REMAP markers

Genetic Resources and Crop Evolution, 2018
Einkorn wheat is known as the donor of ‘A’ genome to cultivated wheat and source of many important genes. Therefore, genetic erosion in cultivated wheat provides a good reason to investigate genetic diversity in these species. In the present study, genetic diversity of 14 populations of Triticum urartu and Triticum boeoticum collected from west and ...

REPRODUCTIVE ISOLATION OF TRITICUM BOEOTICUM AND TRITICUM URARTU AND THE ORIGIN OF THE TETRAPLOID WHEATS

American Journal of Botany, 1976
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.

A proteomic analysis to identify cold acclimation associated proteins in wild wheat (Triticum urartu L.)

Molecular Biology Reports, 2014
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.

Exogenous Quercetin Treatment Provides Insights Into Transcriptional Regulatory Network for Salt Tolerance of Triticum urartu

Physiologia Plantarum : An International Journal for Plant Biology
Quercetin, a well‐known antioxidant, plays a crucial role in the response of plants to biotic and abiotic stresses. Triticum urartu is the donor of the A subgenome of common wheat.

Genomic changes at early stages of formation of allopolyploid Aegilops longissima × Triticum urartu

Russian Journal of Genetics, 2007
Using the model of synthetic allopolyploid Aegilops longissima TL05 x Triticum urartu TMU06 of the first generation, the degree and character of changes in subtelomeric, microsatellite and random amplified DNA sequences (RAPD) on early stage of polyploidization was estimated.

Genome-wide identification and resistance expression analysis of the NBS gene family in Triticum urartu

Genes & Genomics, 2017
As the largest class of resistant genes, the nucleotide binding site (NBS) has been studied extensively at a genome-wide level in rice, sorghum, maize, barley and hexaploid wheat. However, no such comprehensive analysis has been conducted of the NBS gene family in Triticum urartu, the donor of the A genome to the common wheat.

[Identification and analysis of the NAC transcription factor family in Triticum urartu].

Yi chuan = Hereditas, 2016
NAC transcription factors are one of plant-specific gene families with diverse functions, and they regulate plant development, organ formation and stress responses. Currently, the researches about NAC transcription factors mainly focus on model plants, Arabidopsis and rice, whereas such studies are hardly reported in wheat and other plants.

Microsatellite mapping of a Triticum urartu Tum. derived powdery mildew resistance gene transferred to common wheat (Triticum aestivum L.)

Theoretical and Applied Genetics, 2005
A powdery mildew resistance gene from Triticum urartu Tum. accession UR206 was successfully transferred into hexaploid wheat (Triticum aestivum L.) through crossing and backcrossing. The F1 plants, which had 28 chromosomes and an average of 5.32 bivalents and 17.36 univalents in meiotic pollen mother cells (PMC), were obtained through embryos rescued ...

Genetic diversity in wild diploid wheats Triticum monococcum var. boeoticum and T. urartu (Poaceae)

Theoretical and Applied Genetics, 1989
The genetic diversity of two wild diploid wheat species, Triticum monococcum var. boeoticum and T. urartu, was assessed using starch gel electrophoresis. Genetic diversity is uniformly low in both species. Number of alleles per locus was very low with a mean of 1.22 for T. monococcum var. boeoticum and 1.19 in T. urartu.

Analysis of Triticum boeoticum and Triticum urartu seed defensins: To the problem of the origin of polyploid wheat genomes

Biochimie, 2008
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
