The German Television ZDF reported on Sunday May 21 that a German researcher found a gene transfer from genetically engineered rapeseed to bacteria and fungi in the gut of honey bees. Prof. Hans-Hinrich Kaatz from the Institut für Bienenkunde (Institute for bee research) at the University of Jena experimented during the last three years with honey bees on an experimental field with transgenic rapeseed in Saxony, Germany.

The field trial was performed by AgrEvo, the rapeseed [fyi: canola is a rapeseed oil] was engineered to resist the herbicide glufosinate (Liberty, Basta). Prof. Kaatz built nets in the field with the transgenic rapeseed and let the bees fly freely within the net. At the beehives, he installed pollen traps in order to sample the pollen loads from the bees´ hindlegs when entering the hive.

This pollen was fed to young honey bees in the laboratory. (Pollen is the natural diet of young bees which need a high protein diet). Then Prof.Kaatz took the intestine out of the young bees and spread the contents on growth medium to grow the microorganisms.

He probed the microorganisms for the pat-gene, the gene that conferes resistance to glufosinate. In some bacteria and also in a yeast hefound the pat-gene. This indicates that the gene from the genetically engineered rapeseed was transferred in the bee´s gut to the microbes.
