Phenotypic diversity of bread wheat lines with introgressions from the diploid cereal Aegilops speltoides for technological properties of grain and f lour [PDF]
Вавиловский журнал генетики и селекции, 2020 The creation of varieties adapted to changing environmental conditions, resistant to various pathogens, and satisfying various grain purposes is impossible without using the genetic diversity of wheat.

Cloning of the wheat leaf rust resistance gene Lr47 introgressed from Aegilops speltoides [PDF]
Nature Communications, 2023 Leaf rust, caused by Puccinia triticina Eriksson (Pt), is one of the most severe foliar diseases of wheat. Breeding for leaf rust resistance is a practical and sustainable method to control this devastating disease.

Transcriptome based identification and validation of heat stress transcription factors in wheat progenitor species Aegilops speltoides [PDF]
Scientific Reports, 2021 Wheat, one of the major cereal crops worldwide, get adversely affected by rising global temperature. We have identified the diploid B genome progenitor of wheat, Aegilops speltoides (SS), as a potential donor for heat stress tolerance.

Transposable Elements in the Organization and Diversification of the Genome of Aegilops speltoides Tausch (Poaceae, Triticeae) [PDF]
International Journal of Genomics, 2018 Repetitive DNA—specifically, transposable elements (TEs)—is a prevailing genomic fraction in cereals that underlies extensive genome reshuffling and intraspecific diversification in the wild.

Refined chloroplast annotations, repeat profiles, and phylogenomic evidence reveal maternal lineage shifts and independent evolution in the Triticum-Aegilops complex [PDF]
BMC Plant BiologyBackground The Triticum-Aegilops complex has a complex reticulate evolutionary history shaped by multiple hybridization and polyploidization events. While nuclear genome relationships have been extensively explored, the maternal inheritance patterns ...

Introgression of the Aegilops speltoides Su1-Ph1 Suppressor into Wheat [PDF]
Frontiers in Plant Science, 2017 Meiotic pairing between homoeologous chromosomes in polyploid wheat is inhibited by the Ph1 locus on the long arm of chromosome 5 in the B genome.

B chromosomes of Aegilops speltoides are enriched in organelle genome-derived sequences. [PDF]
PLoS ONE, 2014 B chromosomes (Bs) are dispensable components of the genome exhibiting non-Mendelian inheritance. Chromosome counts and flow cytometric analysis of the grass species Aegilops speltoides revealed a tissue-type specific distribution of the roughly 570 Mbp ...

Supernumerary B chromosomes of Aegilops speltoides undergo precise elimination in roots early in embryo development [PDF]
Nature Communications, 2020 B chromosomes are supernumerary chromosomes exhibiting dramatic differences between different organs in same species. Here, the authors show programmed B chromosome elimination in goatgrass starts at the onset of embryo differentiation by nondisjunction ...

A study of the influence of the T2DL.2DS-2SS translocation and the 5S(5D) substitution from Aegilops speltoides on breeding-valuable traits of common wheat [PDF]
Вавиловский журнал генетики и селекцииThe use of the gene pool of wild relatives for expanding the genetic diversity of common wheat is an important task of breeding programs. However, the practical application of common wheat lines with alien genetic material is constrained by the lack of ...
