Allopolyploidy-Induced Rapid Genome Evolution in the Wheat (Aegilops–Triticum) Group
TLDR
Analysis of the rate and time of elimination of eight DNA sequences in F1 hybrids and newly formed allopolyploids of Aegilops and Triticum suggests a role in augmenting the differentiation of homoeologous chromosomes at the polyploid level, thereby providing the physical basis for the diploid-like meiotic behavior of newly formed new species.

Sequence Elimination and Cytosine Methylation Are Rapid and Reproducible Responses of the Genome to Wide Hybridization and Allopolyploidy in Wheat
TLDR
It is found that sequence elimination is one of the major and immediate responses of the wheat genome to wide hybridization or allopolyploidy, that it affects a large fraction of the genome, and that it is reproducible.

Gene loss, silencing and activation in a newly synthesized wheat allotetraploid.
TLDR
Findings show that wide hybridization and chromosome doubling affect gene expression via genetic and epigenetic alterations immediately upon allopolyploid formation and contribute to the genetic diploidization of newly formed allopoly Ploidy in wheat.

Rapid elimination of low-copy DNA sequences in polyploid wheat: a possible mechanism for differentiation of homoeologous chromosomes.
TLDR
It is suggested that genomic changes at the early stages of allopolyploidization, resulting in further divergence of homoeologous chromosomes, may provide the physical basis for the diploid-like meiotic behavior of polyploid wheat.

Transcriptional activation of retrotransposons alters the expression of adjacent genes in wheat
TLDR
It is reported that activation of these antisense or sense transcripts is associated with silencing or activation of the corresponding genes, respectively, which support the view of transposons as potential controlling elements.

Allopolyploidy – a shaping force in the evolution of wheat genomes
TLDR
These phenomena, emphasizing the plasticity of the genome with regards to both structure and function, might improve the adaptability of the newly formed allopolyploids and facilitate their rapid and successful establishment in nature.

Wild wheat. An introduction.
A new powdery mildew resistance gene: Introgression from wild emmer into common wheat and RFLP-based mapping
TLDR
Segregation ratios for resistance in F2 of BL × CASL 2BS and in the recombinant lines, combined with the susceptability of F1 progeny to all tested isolates, indicate that resistance is controlled by a single recessive allele.

Wheat Hybridization and Polyploidization Results in Deregulation of Small RNAs
TLDR
This work performed high-throughput sequencing of small RNAs of parental, intergeneric hybrid, and allopolyploid plants that mimic the genomic changes occurring during bread wheat speciation, and found that the percentage of smallRNAs corresponding to miRNAs increased with ploidy level, while the percentages of siRN as corresponding to TEs decreased.

Triticum dicoccoides: An important genetic resource for increasing zinc and iron concentration in modern cultivated wheat
Abstract One major strategy to increase the level of zinc (Zn) and iron (Fe) in cereal crops, is to exploit the natural genetic variation in seed concentration of these micronutrients. Genotypic…
