Wheat–Aegilops Introgressions

2015
Aegilops is the most closely related genus to Triticum in the tribe Triticeae. Aegilops speltoides Tausch (B genome donor) and Ae. tauschii Coss. (D genome donor) contributed two of the three genomes present in common wheat (Triticum aestivum L., 2n = 6× = 42, AABBDD genomes).

Evaluation of Aegilops tauschii and Aegilops speltoides for acquired thermotolerance: Implications in wheat breeding programmes

Plant Physiology and Biochemistry, 2015
Severe and frequent heat waves are predicted in the near future having dramatic and far-reaching ecological and social impact. The aim of this study was to examine acquired thermotolerance of two Aegilops species: Aegilops tauschii and Aegilops speltoides and study their potential adaptive mechanisms. The effect of two episodes of high heat stress (45 °

Systematical Survey of the Genus Aegilops

2020
In 1928, the Soviet botanist П. М. Жуковский published his works “A critical systematical survey of the species of the genus Aegilops” in Тридыпо Прикладной Бот Ген и Сел (18: 417–609). In this work, he acknowledged 20 species, two of which were newly published. He divided this genus into nine sections. The system was as follows:

Multiple origins of allopolyploid Aegilops triuncialis

Theoretical and Applied Genetics, 2003
Polyploidization is a key component of plant evolution. The number of independent origins of polyploid species traditionally has been underestimated. The objective of this study was to ascertain the number of origins of a tetraploid Aegilops species. We screened 84 primer sets to identify genome-specific primer sets for the tetraploid wheat relative ...

Identification of Pm58 from Aegilops tauschii

Theoretical and Applied Genetics, 2017
A novel powdery mildew-resistance gene, designated Pm58, was introgressed directly from Aegilops tauschii to hexaploid wheat, mapped to chromosome 2DS, and confirmed to be effective under field conditions. Selectable KASP™ markers were developed for MAS. Powdery mildew caused by Blumeria graminis (DC.) f. sp.

Genealogical analysis of the use of aegilops (Aegilops L.) genetic material in wheat (Triticum aestivum L.).

Russian Journal of Genetics, 2015
A genealogical analysis of accessions in the global gene pool of the wheat database GRIS4.0 showed that the use of the genetic material of Aegilops in wheat breeding began about half a century ago. During this time, more than 1350 varieties and 9000 lines, the pedigree of which contains Aegilops species, were created in different regions of the world ...

Aegilops tauschii Introgressions in Wheat

2015
A major driver in Aegilops tauschii introgressions comes from the observation that the diploid D genome progenitor possesses a higher genetic diversity compared to their corresponding genomes in bread wheat cultivars and landraces. Since the mid-twentieth century directed efforts at Ae tauschii introgressions into wheat has come from two avenues ...

Nitrate reductases in hexaploid and tetraploid wheats and Aegilops

Theoretical and Applied Genetics, 1990
Nitrate reductase activity (NR activity), protein content (NR protein) and polypeptides were compared in shoots of Triticum aestivum ssp. vulgare (L.) cv Fidel (bread wheat, AABBDD genome), Triticum dicoccum cv Vernal (AABB genome), Aegilops squarrosa var. strangulata (DD genome) and the amphiploid 365 (AABBDD genome), produced by crossing T.

Evolutionary genomics of two diploid goat grass species belonging to the section Sitopsis of Aegilops, Aegilops longissima, and Aegilops sharonensis

The Plant Journal
SUMMARYAegilops longissima and Ae. sharonensis, being classified into the Sitopsis section of genus Aegilops, are distinct species both taxonomically and ecologically. Nevertheless, earlier observations indicate that the two species are not reproductively isolated to full extent and can inter‐bred upon secondary contact.

Genomic analysis in the genus Aegilops.

Theoretical and Applied Genetics, 1992
Hybrids between different Aegilops species and Secale cereale were studied at metaphase I by means of a C-banding technique. On the basis of differences in the C-banding patterns of some of the chromosomes of these hybrids it was possible to carry out an accurate analysis of several types of Aegilops-Aegilops and Aegilops-Secale chromosome associations
