With Nanotubes, Gene Delivery Easy in Plants: New Discovery


To deliver a gene, the researchers graft it onto a carbon nanotube, which is tiny enough to slip easily through a plant’s tough cell wall

To date, most genetic engineering of plants is done by firing genes into the tissue—a process known as biolistics—or delivering genes via bacteria. Both are successful only a small percentage of the time, which is a major limitation for scientists seeking to create disease- or drought-resistant crops or to engineer plants so they’re more easily converted to biofuels.
