Eucalyptus
Eucalyptus
Because of the long generation time of
woody species and the presence of lignified tissues, a main problem in
transformation of these species is the rapid generation of tissues amenable to
DNA introduction by various methods. This is reflected in the methods described
in the patents and applications described below.
Summary
Patent applications on Agrobacterium-mediate transformation of Eucalyptus have been filed mainly by four private companies:
- Shell International Research Maatschappij has a granted Australian patent related to the production of genetically modified Eucalyptus by transforming Eucalyptus tissue or cells with Agrobacterium having gene(s) of interest. As part of the invention, phenylurea is used to induce shoot formation from the transformed Eucalyptus cells. This patent has expired, so the technology described in it is now in the public domain.
- Oji Paper Co., from Japan, has granted patents in Australia and the United States related to the transformation of adventitious shoots from a mature Eucalyptus tree, using A. tumefaciens; and
- Genesis Research & Development Corp. and Fletcher Challenge Forests Ltd (both based in NZ), had a granted patent in the United States on a method used to produce material amenable to Agrobacterium-mediated transformation. The method is described for eucalypt and pine trees. However this patent and other patent applications in this patent family have been abandoned. Genesis filed an unrelated patent application published in 2005.
- ArborGen, now the assignee for related patent applications by Westvaco, has patent applications pending in the USA and Brazil on methods used for Agrobacterium-mediated transformation.
Notice that the claims in pending applications may vary in scope if granted.
