The GMR editorial staff was alerted about some manuscripts that were found to be substantially equal. The Publisher and Editor decided to retract these articles in accordance with the recommendations of the Committee on Publication Ethics (COPE). After a thorough investigation, we have strong reason to believe that the peer review process was failure and, after review and contacting the authors, the editors of Genetics and Molecular Research decided to retract these articles. The authors and their institutions were advised of this serious breach of ethics. The articles containing plagiarism in common with other publications are: Peng ZA, Lu RB, Xiao DM and Xiao ZM (2016).
