BLGY1211 Environmental safety
Environmental concerns; gene flow from GM plants
Environmental or economic harm spread and persistence survives outside of
cultivation Introduction of transgenic plant pollen flow to wild relative
hybrid forms gene introgression to wild relatives environmental or economic
harm
Promoters for delivering bionematicides
Will introgression occur into a wild relative
Introgression more likely is an advantage conferred on the relative (e.g. pest or
disease resistance) Herbicide resistance confer benefits for weeds in field but not
natural environments (‘superweeds’)
Gaining one transgene unlikely to turn a harmless plant into a weed
A particular issue for crops in their centres of diversity (e.g. potato and the Andes)
many relatives cross fertilise in the field and these relative are often nematode
susceptible male sterile cultivars to trial the benefits while risk of stable
introgression is assessed this solution not available for seed crops
Weighing risks against benefits for food security crop species, geographical
locality and trait are all important
Male sterile potato; one means of limiting gene flow
Concern over a gm crop in its centre of origin
