The EFSA GMO panel assessed the oilseed rape MON 94100 which was developed to confer tolerance to dicamba herbicide. Oilseed rape MON 94100 expresses two variants of the DMO protein: DMO and DMO + 27. The DMO protein demethylates dicamba, producing 3,6-dichlorosalicylic acid and formaldehyde, conferring tolerance to dicamba-based herbicides. The inserted gene construct involves genetic information from two viruses, two plants (from other species) and from bacteria.
