food-plant varieties, the possibility of introducing new
allergens into pollen, or the possibility that previously
unknown protein combinations now being produced in food plants
will have unforeseen secondary or pleiotropic effects. The use
of antibiotic-resistance marker genes has also given rise to

and viral coat proteins), the emphasis has not been on detailed
assessments of safety for humans or domestic an
