Wheat Chinese Spring IWGSC RefSeq v1.0 genome assembly (2018)

A worldwide panel of 487 genotypes that included wild diploid and tetraploid relatives, domesticated tetraploid and hexaploid landraces, old cultivars and modern elite cultivars were assembled and their exome capture sequence data were mapped onto the IWGSC ‘Chinese Spring’ reference genome to reveal 620,158 high-confidence genetic variants (including 595,939 SNPs and indels between hexaploid genotypes) distributed across 41,032 physically ordered wheat genes.

The Wheat Target Induced Local Lesions In Genome (TILLING) project based on the tetraploid wheat line Triticum turgidum cv. Kronos. This project entails targeted re-sequencing of the protein coding regions of over 1500 EMS mutagenized individuals from the Kronos cultivar. In each wheat line, mutations were identified in protein-coding regions and their effects on protein function were predicted. Link to the journal article: link.

Bread wheat is an allopolyploid species with a large, highly repetitive genome. To investigate the impact of selection on variants distributed among homoeologous wheat genomes and to build a foundation for understanding genotype-phenotype relationships, we performed population-scale re-sequencing of a diverse panel of wheat lines. link to paper.

G4 motifs were identified across the 21 chromosomes. Stats: featureCount: 1,071,813; featureDensity: 76 G4s/Mb. G-quadruplexes in wheat paper can be accessed here.
