Engineered plant DNA: regeneration and inheritance in tobacco

What changed

Barton and colleagues regenerated tobacco plants containing engineered T-DNA and followed its transmission to progeny. The experiment connected plant transformation with recovery of whole plants and inheritance.

Scientific scope

Barton and colleagues regenerated tobacco plants containing engineered T-DNA and followed its transmission to progeny. The experiment connected plant transformation with recovery of whole plants and inheritance. Scope limitation: This is a specific experimental paper among several contemporaneous plant-transformation advances, not sole invention of all genetically engineered crops. Tobacco regeneration does not itself establish field benefit, ecological safety or suitability in other species.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. This is a specific experimental paper among several contemporaneous plant-transformation advances, not sole invention of all genetically engineered crops.
