The bans were originally put in place in 1998 because of concerns about gene escape into the environment.
Friends of the Earth said Mr Morley justified the British position, saying that he had to vote on the basis of the available science, whilst his department was holding research confirming the risk of gene escape from GM oilseed rape.
That means transgenic plants created by the T-DNA vector system have a ready route for horizontal gene escape, via Agrobacterium, helped by the ordinary conjugative mechanisms of many other bacteria that cause diseases.
A report submitted to MAFF in 1997 had indeed raised the possibility that Agrobacterium tumefaciens could be a vector for gene escape (15, 16).

He is little concerned about the gene escape into wild plants to produce "superweeds," because a cross between a GM crop and a wild relative will involve all of the GM crop's genome, including the characteristics that make it dependent on the tender loving care of the farmer for survival.
Kansas State University, Manhattan, Kansas -- $160,000 to study potential gene escape in imidazolinone resistant sunflowers and the impact on related wild species.
They exacerbate weed problems in two ways: [1] by the natural evolution of herbicide resistant weeds through repeated exposure to herbicide and; [2] by gene escape from crops to natural populations of plants.
Gene escape from cultivated plants is documented for crops including cotton, cucumber, corn, millet, canola, quinoa, radish, rice, sorghum, strawberry, sugarbeets, and watermelon.
The creation of new weeds by continued use of chemicals or gene escape invites the kinds of solutions the chemical industry is eager to provide.
Once an engineered gene escapes into the natural environment, it spreads rapidly and has the potential to alter plant evolution.
Most previous studies of gene escapes have focused on pollen straying far and wide, says Jean-Francois Arnaud of the Universite de Lille 1 in France.
