This already happens in nature by various means, one of which is viral.
There is no absolute genetic sanctity in nature. As for transgenics,
especially in plants, one tool for introducing foreign genes is
agrobacteria. This microbe is fully capable of vectoring interspecific
DNA without lab manipulation. The DNA so introduced in the lab does not
carry any special DNA destabilizer, rather, it depends on the rather
scattershot and low-yield natural method of homologous recombination or
illegitimate recombination. Another method has absolutely no danger of
transfering a new DNA transfer method to nature: the gene gun. DNA of
interest bound to microscopic gold beads and shot into cells offers
absolutely no threat of tranfering into an uncontrollable means of
interspecific gene transfer in the wild.
