Parameters Affecting Gene Flow in Oilseed Rape
March 14, 2008| |
The transfer of herbicide resistance genes via pollen-mediated gene flow from genetically engineered (GE) crops to non-GE crops is often raised as a concern as it relates to co-existence of different agricultural cultivation systems and weed management. Hence, a literature search for worldwide studies on cross-fertilization in oilseed rape was done to identify the major factors that affect pollen-mediated gene flow.
Alexandra Hüsken and Antje Dietz-Pfeilstetter of the Federal Biological Research Centre for Agriculture and Forestry in Braunschweig discuss parameters affecting gene flow, that include shape, orientation, and size of pollen source and recipient field; isolation distance and border crops between pollen source and recipient field; and local environment and climatic conditions.
