Applicability of Aegilops tauschii drought tolerance traits to breeding of hexaploid wheat

Breeding Science, 2011
Few genes are available to develop drought-tolerant bread wheat (Triticum aestivum L.) cultivars. One way to enhance bread wheat's genetic diversity would be to take advantage of the diversity of wild species by creating synthetic hexaploid wheat (SW) with the genomic constitution of bread wheat.

Characterization of low-molecular-weight glutenin genes in Aegilops tauschii

Theoretical and Applied Genetics, 2004
This paper reports the characterization of the low-molecular-weight (LMW) glutenin gene family of Aegilops tauschii (syn. Triticum tauschii), the D-genome donor of hexaploid wheat. By analysis of bacterial artificial chromosome (BAC) clones positive for hybridization with an LMW glutenin probe, seven unique LMW glutenin genes were identified.

Haplotype variants of the stripe rust resistance gene Yr28 in Aegilops tauschii

Theoretical and Applied Genetics, 2022
Stripe rust resistance gene YrAet672 from Aegilops tauschii accession CPI110672 encodes a nucleotide-binding and leucine-rich repeat domain containing protein similar to YrAS2388 and both these members were haplotypes of Yr28. New sources of host resistance are required to counter the continued emergence of new pathotypes of the wheat stripe rust ...

Seed protein and isozyme variations in Triticum tauschii (Aegilops squarrosa)

Theoretical and Applied Genetics, 1993
Sixty Triticum tauschii (Aegilops squarrosa, 2n=2x=14, DD) accessions were evaluated for the variability of high-molecular-weight (HMW) glutenins, gliadins and isozymes of seed esterase, β-amylase and glucose-phosphate isomerase. Wide variability was observed for HMW-glutenins and gliadins.

Cellular and physiological responses to drought stress in Aegilops tauschii genotypes

Cellular and Molecular Biology, 2019
Drought stress is one of the most important limiting factors in crop yield through impact on the cellular and physiological functions of the plant. Therefore, the study of physiological responses of plants can help to better understanding the drought tolerance mechanisms.

Evaluation of Aegilops tauschii Cosson for preharvest sprouting tolerance

Genetic Resources and Crop Evolution, 1998
On day 21, total germination percentages of threshed seeds of Ae. tauschii ranged from 0.0 to 92.6, indicating a large variation in preharvest sprouting tolerance. Out of 46 Ae. tauschii accessions, seven had a germination index lower than ten, which indicates good tolerance to preharvest sprouting and usefulness for common wheat (Triticum aestivum L.)

Diversity and distribution of puroindoline-D1 genes in Aegilops tauschii

Genetic Resources and Crop Evolution, 2015
Puroindoline-D1 genes are the key genes that decide kernel texture in bread wheat, but limited genetic resources have impeded the improvement of wheat quality. In this study, the puroindoline-D1 genes from 110 accessions of Aegilops tauschii Coss. (the D genomic ancestor of bread wheat) were isolated and sequenced to identify new alleles and discover ...

The structure of the Aegilops tauschii genepool and the evolution of hexaploid wheat

Theoretical and Applied Genetics, 1998
Polymorphism in the lengths of restriction fragments at 53 single-copy loci, the rRNA locus Nor3, and the high-molecular-weight glutenin locus Glu1 was investigated in the D genome of hexaploid Triticum aestivum and that of Aegilops tauschii, the source of the T. aestivum D genome. The distribution of genetic variation in Ae.

Transcriptomic analysis of Aegilops tauschii during long-term salinity stress

Functional & Integrative Genomics, 2018
Aegilops tauschii is the diploid progenitor of the bread wheat D-genome. It originated from Iran and is a source of abiotic stress tolerance genes. However, little is known about the molecular events of salinity tolerance in Ae. tauschii. This study investigates the leaf transcriptional changes associated with long-term salt stress.

Genetic diversity of avenin-like b genes in Aegilops tauschii Coss

Genetica, 2017
Avenin-like storage proteins influence the rheological properties and processing quality in common wheat, and the discovery of new alleles will benefit wheat quality improvement. In this study, 13 avenin-like b alleles (TaALPb7D-A-M) were discovered in 108 Aegilops tauschii Coss. accessions.
