title: Releasing genetically engineered plants: Present proposals and possible hazards.
abstract: Worldwide the majority of current proposals to release genetically modified organisms concern plants; most are for small changes in common crop plants and present little apparent hazard. However, there is much confusion about how plants become pests, and implausible risk factors are appearing in the literature and before committees. It is dangerous to estimate the risks from first principles because of the immaturity of plant population biology and the lack of empirical data. Regulatory agencies should concentrate on obtaining realistic assessment of hazards, and not attempt to balance notional benefits and disbenefits.
