title: Data from: Detection of airborne genetically modified maize pollen by real-time PCR

description: The cultivation of genetically modified (GM) crops has raised in the
 European Union and other parts of the world numerous concerns about their
 environmental and economic impact. Especially outcrossing of genetically
 modified organisms (GMO) was from the beginning a critical issue as
 airborne pollen has been considered an important way of GMO dispersal.
 Here, we investigate the use of airborne pollen sampling combined with
 microscopic analysis and molecular PCR analysis as an approach to monitor
 GM maize cultivations in a specific area. Field trial experiments in the
 European Union and South America demonstrated the applicability of the
 approach under different climate conditions, in rural and semi-urban
 environment, even at very low levels of airborne pollen. The study
 documents in detail the sampling of GM pollen, sample DNA extraction and
 real-time PCR analysis. Our results suggest that this ''GM
 pollen monitoring by bioaerosol sampling and PCR screening" approach
 might represent an aid in managing the co-cultivation of GM and non-GM
 crops, especially in the surveillance of GM-free areas, centres of origin,
 and natural reserves.

Only when identity was higher than 97% genus and/or species identification was attempted.
