OWWC Phase II – Open Wild Wheat

The Open Wild Wheat Consortium Phase II began in January of 2022.

We are expanding the previous Ae. tauschii panel of 242 non-redundant accessions to over 600 accessions from Lineages 1, 2, and 3, constituting one of the largest collections of this wild wheat species.

Whole genome shotgun (WGS) sequencing between 7.5 and 10-fold coverage of the additional accessions will be carried out to generate an extensive sequence-configured panel for this wild wheat.

The hallmark of the OWWC Phase II will be the creation of an Aegilops tauschii pangenome resource.

The pangenome will be generated from high-quality reference assemblies for an initial collection of 39 accessions. These accessions are strategically important to the consortium, as well as representative of the genetic diversity across the previously genotyped panel in Phase I.

The selected pangenome accessions are highlighted in bold within each clade. Not all accessions are shown since some were not included in OWWC Phase I.

Data utilization

The raw data generated in Phase II will be made available under Toronto agreement.

By using the data you will agree to:

Respect the rights of the data producers and contributors to analyze and publish the first global analyses and certain other reserved analyses of this data set in a peer-reviewed publication
Not redistribute, release, or otherwise provide access to the data to anyone outside of the group, until the data has been published and submitted to the public data repositories
Contact the authors to discuss any plans to publish data or analyses that utilize this data to avoid the overlap of any planned analyses
Fully cite the pre-publication data along with any applicable versioning details
Understand that this data as accessed is pre-competitive and is not patentable in its present state

This agreement does not expire by time but only upon publication of the first global analysis for the OWWC Phase II by the data producers and contributors.
