Sorry, I have no information to contribute, though I would like to
add my question to yours:

ISTM that the "real" question is whether "engineered" genes are more
likely to move from food to bacteria than are "natural" genes. But what
little I know of how "engineered" genes are inserted into food plant
genomes would seem to make the hypothesis of higher mobility seem quite
plausible. My question is: how do "engineers" actually implant the
new gene into the plant genome these days?
