Engineering plants for improved crop production and performance are not a new technology. Advancements in recombinant DNA tools have allowed for developments in agriculture such as engineering plants for pest and disease control, drought resistance, increased nutritional value content, and production of pharmaceuticals. With these advancements, concerns have risen over genetically engineered DNA entering natural ecosystems. This work focused on modeling the fate of transgenic DNA released from plant tissue into the soil --Abstract, page iii
