WITHDRAWN: Chloroplast genome evolution of Berberis (Berberidaceae): Implications for phylogeny and metabarcoding.

After consultation with external experts, the authors acknowledged discrepancies in the classification of certain Berberis samples discussed in the article. Berberis is one of the most complex plant genera, and identifications are very hard, limited to only a handful of experts due to rampant hybridizations and other issues of reticulate evolution. This article has therefore been withdrawn at the request of the authors and with the consent of the editor until the species identification issue has been resolved. The Publisher apologizes for any inconvenience this may cause. The full Elsevier Policy on Article Withdrawal can be found at https://www.elsevier.com/about/policies/article-withdrawal.
