Retraction of: Scientific Reports, published online 20 July 2017

The Editors have retracted this article.

After publication concerns were raised that there were anomalies in Supplementary Figures 1 and 2. However, the authors were unable to provide higher resolution images to allow the veracity of these data to be confirmed. Additionally the graph showing the genetic diversity of the wild almond species, which is a part of Figures 1, 2, 3 and 5, appears to be a duplication of a graph showing the genetic diversity of the liquorice species in Figure 2 in Hakimi et al.1, of the barley species in Figure 2 in Rouhain et al.2, and of olive species in Figures 1 and 2 in Khaleghi et al.3.

The Editors therefore no longer have confidence in the validity of the results and conclusions reported in this article.

All authors agree with the retraction.
