One more then I'll stop! This is what I was originally looking for, it's kind of a primer on genetic engineering from the same source. It makes several important points, such as that adding genes from plant A into plant B may induce a serious or fatal reaction in a person who is highly allergic to A but thought he was eating B. Or, that if we make a plant produce a particular gene product, it will be expressed by ALL parts of a plant, not just the part we're interested in modifying--and we have no idea what the consequences will be. (In that respect,we're not nearly as smart as plants!)
