Wheat manuscript. ‘Tracing the ancestry of modern bread wheats’ This manuscript was prepared by ▇▇▇▇▇▇ ▇▇▇▇▇ and colleagues from across the WHEALBI consortium and has been submitted to Nature Genetics (authors and affiliations listed in Appendix I) The manuscript describes the exome capture data of 500 carefully selected lines representing a worldwide collection of di- and tetraploid wild relatives as well as old hexaploid landraces up to modern elite cultivars. The exome capture data covers genetic variation at ~1/2 of all wheat genes. Together these provide a comprehensive overview of wheat genetic diversity at a range of scales (gene, region, chromosome, genome), delivering a rich resource for future exploitation by both the academic and agricultural research communities (Figure 1). Figure 1. Temporal evolution of wheat diversity. A- Nucleotide diversity (y-axis) from the hexaploid wheat accessions (x-axis) between subgenomes (A, B and D) and historical groups (landraces, old cultivars, cultivars and modern varieties) covering the last centuries of breeding (cf timescale legend in the white box)(From Pont et al., 2019) The manuscript provides clear novel insights into wheat ancestry in (i) unveiling genomic signatures of domestication and breeding at the chromosome and ▇▇▇▇ ▇▇▇▇▇▇ supporting independent targets of breeding in Asia and Europe following the eat -west expansion from the center of origin, (ii) delivering genomic drivers of key traits (heading date and photoperiod) related to wheat adaptation during the green revolution, (iii) proposing that modern cultivated bread wheat are the result of recurrent hybridization and gene flow between diploid, tetraploid and hexaploid progenitors with T. durum lineage being the most likely ancestor of today’s bread wheat cultivated germplasm. The current manuscript supports a reconciled model of wheat evolution, expansion and associated selected genes since its domestication and provides novel avenues for future breeding improvement.
