Desired gene
Traditional plant breedingDNA is a strand of genes, much like a strand of pearls. Traditional plant breeding combines many genes at once.
Traditional donor Commercial variety New variety
Desired Gene
X =(crosses)
(many genes are transferred)
Plant biotechnologyUsing plant biotechnology, a single gene may be added to the strand.

“No conceptual distinction exists between genetic modification of plants and microorganisms by classical methods or by molecular techniques that modify DNA and transfer genes.”

“Let food be your medicine and medicine be your food.”
— Hippocrates
23
Rice enriched with vitamin A
24
High-protein corn in Africa, Asia and Latin America
25
“Agricultural biotechnology holds great promise for Africa. We don’t want to be denied this technology because of a misguided notion that we don’t understand the dangers of the future consequences.”
— Hassan Adamu, Nigerian Minister of Agriculture and Rural Development

Bring environmentally sensitive land under the plow, or increase productivity on existing land?
31
Plant biotechnology means less spraying
32
Plant biotechnology means more conservation tillage
33
Better for the Environment
Mangrove genes transferred to annual crops to promote tolerance to saline soils.

“A powerful tool for fostering ecofarming as well as for enhancing the productivity of rainfed and saline soils.”
— M.S. Swaminatham 1987 World Food Prize recipient

Government regulation
Less trust in food regulatory systems in Europe.

“We have recently advanced our knowledge of genetics to a point where we can manipulate life in a way never intended by nature. We must proceed with the utmost caution in the application of this new found knowledge.”
— Luther Burbank

“The turning point in agriculture was hybrid wheat.”
— Jacob BronowskiThe Ascent of Man

Plant biotechnology represents the next leap forward
44
“If they can give us a better tomato, I’m for it.”
— Julia Child

“Scientists around the world agree that the new ‘gene-splicing’ technology lowers even further the already minimal risk associated with introducing new plant varieties into the food supply.”
— Professor Henry Miller, Stanford University
46
“We are increasingly encouraged that the advantages of genetic engineering of plants and animals are greater than the risks . . . We cannot agree with the position of some groups that say it is against the will of God to meddle with the genetic make-up of plants and animals.”
— Bishop Elio Sgreccia, vice president of the Pontifical Academy for Life

“The more people know, the more they support biotechnology.”
— Council for Biotechnology Information Research
