The myth of “substantial equivalence” between GMOs and non-crops (called “isolines”) takes yet another hard science hit.
A team of researchers in Mexico City has published their of genetic data on rice, canola, maize, sunflower, and pumpkin. They looked at wild, , and non- cultivated varieties of these five crops, analyzing phenotypic change.
The reported here on Hygeia.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 targeted scientists added to the and hope to express. For example, a corn plant engineered to express the toxin should not be different from normal corn in other ways, as has been
However, genetics are complicated and unintended consequences often occur. Of the five crops analyzed in this study, maize, pumpkin and rice showed the most variation betweenand non- cultivars. These three crops demonstrated wide variation for related to days to flowering, number of seeds/fruit, plant height, and pollen viability. In fact, the researchers report that for non- and cultivars of maize, pumpkin and rice, “almost all analyzed differ statistically.”
This latest report of “unintended consequences” from the genetic engineering process again raises questions about the official concerns about GMOs elsewhere on Hygeia.policy claiming that other that GMOs are “substantial equivalent” or “functionally equivalent” to the original, non- isoline. We report on this and other
