GMOs with stacked traits

OBJECTIVES:

Overestimating the percentage GM content for GMOs with stacked traits could lead to unjustified legal consequences for affected stakeholders. This research project is developing ways to properly quantify GMOs with more than one target foreign gene.


APPROACH:

The first phase of the project is to write a position document discussing the challenges and limitations posed by GMOs with stacked genes and should present some potential solutions. In addition to technical issues, the document discusses how gene stacked GMOs are dealt with from a legal standpoint around the world. Some policies, for instance, could look at a new GMO derived from a cross between two already approved GMOs and subject it its own approval process. In other places, approved "events" are considered authorised, regardless of whether or not they exist in a plant along with other authorised events.

In the lab, researchers are using anchor-PCR testing on single seeds with stacked transgenes.


SHORT RESULTS:

Review on the world wide authorization of gene stacked GMOs in regulation to cGS and the basis for definition of corresponding unique genetic markers 
A position document providing the definition of gene stacking in plants, as well as its implications in relation to genetics, safety, detectability and European regulations.
