Claims of “substantial equivalence” of GM plants again shown to be false
The myth of “substantial equivalence” between GM crops and their closest non-GM relatives (called “isolines”) has taken yet another scientific hit, this time from a new peer-reviewed paper discussed in an article on the website Hygeia Analytics.
The researchers from Mexico City published their meta-analysis of genetic data on rice, canola, maize, sunflower, and pumpkin. They looked at wild, GMO, and non-GMO cultivated varieties of these five crops, analyzing phenotypic change.
The phenotype of a crop is defined by a set of characteristics expressed by the crop’s genetic code (DNA). In theory, genetically engineered plants will show phenotypic changes only linked to the traits that scientists added to the GMO in the hope that they will be expressed. For example, a corn plant engineered to express the Bt toxin should not be different from normal corn in other ways.
