k-mer matrix Aegilops tauschii diversity panel (Open wild wheat consortium phase II) Part 2/3

Wild wheat relatives of bread wheat represent genetic diversity that can be used for wheat crop improvement. We generated a k-mer presence/absence matrix of over 920 accessions of the wild wheat Aegilops tauschii, the donor of the bread wheat D genome. This dataset was generated under the aegis of Phase II of the Open Wild Wheat Consortium (www.openwildwheat.org)., The full methods are available in the related publication., , # Population genomics of the wild wheat Aegilops tauschii (Open Wild Wheat Consortium) - k-mer matrix PART 2/3-

## **Description of the data and file structure**

*k*-mer presence/absence matrix for the *Aegilops tauschii* diversity panel of over 920 accessions, including genetically redundant accessions.

Resequencing of the *Ae. tauschii* accessions: We generated short-read whole genome sequencing data for 350 *Ae. tauschii* accessions.  PCR-free paired-end libraries were constructed and sequenced on an Illumina Novaseq 6000 instrument, yielding a median 8.3-fold coverage per sample (ranging from 5.87 to 16.86-fold).

*k*-mer matrix generation. We developed and implemented an optimised *k*-mer matrix workflow to generate a presence/absence *k*-mer matrix for large diversity panels ([https://github.com/githubcbrc/KGWASMatrix](https://github.com/githubcbrc/KGWASMatrix)). We counted *k*-mers (*k* = 51) i...
