TL;DR: The developed array and cluster identification algorithms provide an opportunity to infer detailed haplotype structure in polyploid wheat and will serve as an invaluable resource for diversity studies and investigating the genetic basis of trait variation in wheat.

TL;DR: Insight into the genome biology of a polyploid crop provide a springboard for faster gene isolation, rapid genetic marker development, and precise breeding to meet the needs of increasing food demand worldwide.

TL;DR: It is shown that selection likely acts on distinct targets or multiple functionally equivalent alleles in different portions of the geographic range of wheat, suggesting either weak selection pressure or temporal variation in the targets of directional selection during breeding probably associated with changing agricultural practices or environmental conditions.

TL;DR: The results suggest that duplicated homoeologous genes are under purifying selection, and it is hypothesized that allopolyploidy may have increased the likelihood of beneficial allele recovery by broadening the set of possible selection targets.

TL;DR: This study shows that de novo transcriptome assembly of tetraploid wheat benefit from multiple k-mer assembly strategies more than diploids wheat, and demonstrates that phasing approaches originally designed for heterozygous diploid organisms can be used to separate the close homoeologous genomes of tetraspecific wheat.
