Method For The Integration Of Foreign Dna Into Eukaryotic Genomes

View page
US Patent:
6541231, Apr 1, 2003
Filed:
Oct 12, 1999
Appl. No.:
09/415839
Inventors:
Christopher L. Baszczynski - Urbandale IA
Leszek Alexander Lyznik - Johnston IA
William J. Gordon-Kamm - Urbandale IA
Xueni Guan - San Diego CA
Aragula Gururaj Rao - Urbandale IA
Laura A. Tagliani - Ankeny IA
Assignee:
Pioneer Hi-Bred International, Inc. - Des Moines IA
International Classification:
C12N 900
US Classification:
435183, 435193, 435 691, 435 697, 435462, 435468, 800278
Abstract:
Compositions and methods for introducing a DNA of interest into a genomic target site are provided. In particular, the methods and compositions involve the use of a combination of target sites for two site specific recombinases and expression of a chimeric recombinase with dual target site specificity. Thus, the compositions comprise novel site-specific recombinases with specificities to multiple target sites, and nucleotide sequences and expression cassettes encoding these recombinases or target sites. The methods involve transforming a eukaryotic cell having target sites for the novel recombinase with a DNA of interest that is flanked by corresponding target sites. Expression of the recombinase results in integration of the DNA of interest into the genome of the cell. The compositions and methods of the invention have use in the construction of stably transformed eukaryotic cells, and in particular, plant cells. The methods result in the efficient targeted genomic integration of DNA by site-specific recombination.

US Patent:
6664108, Dec 16, 2003
Filed:
Oct 1, 1999
Appl. No.:
09/411826
Inventors:
Christopher L. Baszczynski - Urbandale IA
Leszek Alexander Lyznik - Johnston IA
William J. Gordon-Kamm - Urbandale IA
Xueni Guan - San Diego CA
Assignee:
Pioneer Hi-Bred International, Inc. - Johnston IA
International Classification:
C12N 1582
US Classification:
435469, 435419, 4353201, 536 231, 800278, 800205
Abstract:
The invention relates to methods and compositions for site-specific recombinase-mediated mobilization of viral replicons and associated DNAs of interest from T-DNA. The methods of the invention comprise Agrobacterium-mediated transfer of T-DNA to a plant cell, wherein the T-DNA contains a viral replicon flanked by directly repeated target sites for a site-specific recombinase and optionally a DNA of interest linked to the viral replicon. The DNA of interest may also contain a non-identical target site for the recombinase. An expression cassette for the site-specific recombinase is present on the T-DNA or the plant genome, or is transiently introduced into the plant cell. Expression of the site-specific recombinase in the plant cell results in excision of the viral replicon and the associated DNA of interest. The viral replicon and DNA of interest are then replicated to high copy number in the host plant cell. The compositions of the invention comprise nucleic acids, such as T-DNAs containing a viral DNA flanked by directly repeated target sites for a site-specific recombinase.
