Fate of Transgenes from Transgenic Plants

Transgenes in transgenic plants can potentially reach a wide range of environmental micro-organisms. We have shown that :

1) pathogens can develop in transgenic plants and release plant DNA.
2) soil bacteria can co-infect plants undergoing necrosis.
3) gene transfer between the plant pathogen and a model soil bacteria can occur in planta.
4) for measurable gene transfer, sequences homologous to plant DNA are required.
5) plant DNA is drastically degraded before leaving the plant.
6) plant DNA making it to the soil is also dramatically reduced.
