This study finds molecular presence of transgenic DNA in genomes and geographical regions where it was not supposed to occur. It applies simple methods typical of microbial ecology to a critical question of policy relevance, and received tremendous public attention and media coverage, as the genetic diversity compromised by these findings is considered essential for global food security.
