Consumer concerns over genetically engineered
foods are addressed. Unexpected gene flow, allergies, and increased
resistance to pesticides are feared by some consumers. Potential benefits of genetic engineering are described, including resistance to insects. Transgenic broccoli has been developed that incorporates a gene from Bacillus thuringiensis (Bt) conferring resistance to the diamondback moth. Gene
flow is seen as unlikely if genetically modified
plants have no opportunity to cross-pollinate with related plants or weed species.
allergies have occured with an experimental system in which a gene from Brazil nuts was transferred to soya beans; the resulting bean has been dropped from commercial development.
insects could theoretically develop resistance to Bt plants. Research projects are in progress that seek to clarify the issue.
