RAGES subreport: New genetic engineering technologies

Genetically modified organisms (GMOs), predominantly plants, have been commercially grown in some countries, notably the Americas, since the mid-1990s. Current GMOs have been developed using ‘first generation’ genetic engineering technologies. More recently, new applications of GMOs and new modes of creating novel traits have been developed alongside new genetic engineering technologies. Grafting, cisgenesis and intragenesis, reverse breeding and RNA-directed DNA

methylation (RdDM) either utilise GMOs created using first generation techniques as an intermediary stage or can, in the case of agro-infiltration, unintentionally give rise to GMOs. Most, if not all, of the principal concerns regarding first generation GMOs apply to these new types of GMOs and new genetic engineering techniques. Some novel types of GMOs (e.g. RNA interference (RNAi)-based GM plants) present additional challenges for risk assessment, as do new genetic engineering techniques, such as genome editing.
