Having created golden rice, Potrykus wanted to make sure it reached those for whom it was intended: malnourished children of the developing world. And that, he knew, was not likely to be easy. Why? Because in addition to a full complement of genes from Oryza sativa--the Latin name for...
For about a year now--ever since Potrykus and his chief collaborator, Peter Beyer of the University of Freiburg in Germany, announced their achievement--their golden grain has illuminated an increasingly polarized public debate. At issue is the question of what genetically engineered crops represent. Are they, as their proponents...
The problem interested Potrykus for a number of reasons. For starters, he was attracted by the scientific challenge of transferring not just a single gene, as many had already done, but a group of genes that represented a key part of a biochemical pathway. He was also motivated by complex...
That indeed is what Potrykus announced he and Beyer planned to do. The two scientists soon discovered, however, that giving away golden rice was not going to be as easy as they thought. The genes they transferred and the bacteria they used to transfer those genes were all encumbered by...
Beneath the hyperbolic talk of Frankenfoods and Superweeds, even proponents of agricultural biotechnology agree, lie a number of real concerns. To begin with, all foods, including the transgenic foods created through genetic engineering, are potential sources of allergens. That's because the transferred genes contain instructions for making proteins, and...
