Official documents reveal that Daniel Voytas, a professor at the University of Minnesota and the co-inventor of the genome editing tool TALENs, has been found to have violated basic laboratory biosafety rules for a period of more than two years.

Unapproved and unsupervised genetic engineering in the Voytas lab appears to have included the development of a new commercial technique for rapid production of gene edited plants called Fast-Treated Agrobacterium Co-Culture, or “Fast-TrACC”. The patent-pending technique has been licensed by the University of Minnesota to Calyxt, a controversial biotechnology company co-founded by Voytas and where he serves as Chief Science Officer.
