Agapito-Tenfen et al.'s study looking at the effects of breeding GM plants together to stack multiple artificial DNA constructs into one crop  has thrown a very uncomfortable shadow over Monsanto's 'SmartStax' maize.
Indications from this study are that, even with only two transformation events stacked, there's reduced expression of the novel genes and significant changes in biochemical pathways such as energy-production, detoxification, cellular processes, genetic information processing, and others. If this degree of perturbation happens when only two events are stacked, what is happening in SmartStax which has eight events stacked?
