Recently, We published the paper "Whole-genome sequencing of diverse wheat accessions uncovers genetic changes during modern breeding in China and the United States" on the Plant Cell. You can access these resources from JBorwse. In this study, we performed a comprehensive comparative analysis of a whole-genome resequencing panel of 355 common wheat accessions (representing diverse landraces and modern cultivars from China and the United States) at the phenotypic and genomic levels. The genetic diversity of modern wheat cultivars was clearly reduced compared to landraces. Consistent with these genetic changes, most phenotypes of cultivars from China and the United States were significantly altered. Of the 21 agronomic traits investigated, eight showed convergent changes between the two countries. Moreover, of the 207 loci associated with these 21 traits, more than half overlapped with genomic regions that showed evidence of selection. The distribution of selected loci between the Chinese and American cultivars suggests that breeding for increased productivity in these two regions was accomplished by pyramiding both shared and region-specific variants. This work provides a framework to understand the genetic architecture of the adaptation of wheat to diverse agricultural production environments, as well as guidelines for optimizing breeding strategies to design better wheat varieties.The raw data and sequencing data have been deposited in the National Genomics Data Center (NGDC) database under project CRA005878. The genotype data in variant call formats (VCF) are available in the NGDC database under accession number GVM000315.
Recently, Ahmed et al. published the paper "Einkorn genomics sheds light on history of the oldest domesticated wheat" on the Nature. You can access these resources from BLAST, GetSequence, PrimerServer and JBorwse. In this study, they generated two high-quality genome assemblies including a wild einkorn accession TA299 and a domesticated einkorn landrace TA10622. They found einkorn centromeres are highly dynamic, showing evidence of ancient and recent centromere shifts caused by structural rearrangements. Whole-genome sequencing analysis of a diversity panel uncovered the population structure and evolutionary history of einkorn, revealing complex patterns of hybridizations and introgressions after the dispersal of domesticated einkorn from the Fertile Crescent.

Recently, Li et al. published the paper "Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield" on the Mol Plant. They exome sequenced 287 wheat accessions that were collected in the past 100 years. Population genetics analysis identified 6.7% of the wheat genome that fell in selection sweeps between landraces and cultivars with genes known for yield improvement. These sweeps were asymmetrically distributed on the A- and B-sub-genomes with regulatory genes being favorably selected.

Recently, Li et al. published the paper "Genome sequences of the five Sitopsis species of Aegilops and the origin of polyploid wheat B-subgenome" on the Mol Plant. They report the assembly of chromosome-level genome sequences of all five Sitopsis species, namely Ae. bicornis, Ae. longissima, Ae. searsii, Ae. sharonensis, and Ae. speltoides. Their results support that the donor of common wheat B-subgenome is a distinct, and most probably extinct, diploid species that diverged from an ancestral progenitor of the B-lineage to which the still extant Ae. speltoides and Am. muticum belong.
