Biosafety of transgenic trees

Project

 (c)

 
Gene transfer and biosafety of biotechnologically grown trees

Following the year 2008 transgenic trees to be foreseen for non-commercial field releases as well as for commercial applications shouldn't contain any antibiotic resistance gene marker. Further, it has been claimed in particular for trees that the foreign genes introduced into tree genomes should be positioned at genomic locations which has been found suitable for integration of forest genes. In this project the possibilities for a targeted transfer of transgenes as well the elimination of marke

Background and Objective

In this project the possibilities for a targeted transfer of transgenes as well the elimination of marker genes will be studied. In frame of a biological biosafety research are these investigations very important in order to assess possible risks following the practical application of such systems.

Approach

This project is based on preliminary with using recombination systems, which has been successfully tested in annual plants. Also for aspen it has been shown, that the recombination systems Cre/lox as well FLP/FRT work well. For risk assessment studies it has to be analysed whether pleiotropic effects can be observed in transgenic trees carrying recombination systems.
