Quantification of Cry proteins in soil and influence on the microbial colonization of maize roots
Project
Project code: 0315215C
Contract period: 01.04.2008
- 31.03.2011
Purpose of research: Applied research
In the field, maize plants provide a possible habitat for a wide range of micro-organisms (bacteria, fungi and archaea) both inside their roots and on the root surface. The aim of this project was to compare the diversity of the naturally occurring micro-organism communities in the genetically modified Bt maize line MON89034 x MON88017 with the diversity in conventionally bred maize varieties. This GM line produces three different Bt proteins (Cry1A.105, Cry2Ab and Cry3Bb1), which can be measured in the soil using specific highly sensitive detection systems.
The project aimed to measure the quantities of the three Bt proteins in the roots and soil over the course of the three-year field trial to investigate any correlations between potential ecological effects and concentrations of Bt proteins. In addition, the project investigated the impacts of Bt proteins on the diversity of micro-organisms in the intestines of bees.
