A method for the particle-mediated transformation of cotton permits the direct genetic engineering of elite cotton lines without the need for tissue culture or callus proliferation. The technique involves excising the embryonic axes from germinating seeds and blasting particles carrying foreign genes into the embryonic axes. When the treated axes are released from an initial cytokinin treatment, the meristems recover and generate a shoot. By using a marker gene, the transformant population of the shoots can readily be identified. In this fashion, direct and expeditious transformations of elite cotton lines in Pima Acala, Sea Island and, Upland varieties can routinely be achieved.

Why it's free to use
- Filed March 5, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 5, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 5, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
