Patent number: 6300545Abstract: The invention relates to methods and compositions for site-specific recombinase-mediated mobilization of viral replicons from T-DNA. The methods 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.Type: GrantFiled: November 17, 1998Date of Patent: October 9, 2001Assignee: Pioneer Hi-Bred International, Inc.Inventors: Christopher L. Baszczynski, Leszek Alexander Lyznik, William J. Gordon-Kamm, Xueni Guan

Patent number: 6278042Abstract: This invention relates to an isolated nucleic acid fragment encoding a heavy metal transporter. The invention also relates to the construction of a chimeric gene encoding all or a portion of the heavy metal transporter, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the heavy metal transporter in a transformed host cell.Type: GrantFiled: December 14, 1999Date of Patent: August 21, 2001Assignee: E.I. du Pont de Nemours and CompanyInventors: Stephen M. Allen, J. Antoni Rafalski, Hajime Sakai

Patent number: 6265638Abstract: Compositions and methods for the efficient co-transformation of a plant are provided. Novel compositions are Agrobacterium strains that have been engineered to comprise at least two binary vector plasmids in addition to a helper plasmid comprising the vir functions. Each of the binary vectors comprises its own T-DNA borders flanking a heterologous nucleotide sequence of interest. Methods of the invention comprise the use of these novel multiple-binary vector Agrobacterium strains to co-transform a plant. In this manner, heterologous nucleotide sequences of interest residing on different binary vectors can be independently introduced into the plant in a single transformation event and incorporated in the plant's nuclear DNA in an unlinked manner. The invention also provides for regenerated, fertile transgenic plants, transgenic seeds produced therefrom, and T1 and subsequent generations.Type: GrantFiled: September 28, 1999Date of Patent: July 24, 2001Assignee: Pioneer Hi-Bred International, Inc.Inventors: Dennis L. Bidney, Christopher Jay Scelonge

Patent number: 6225105Abstract: Acetolactate synthase (ALS), a key enzyme in the biosynthesis of valine, leucine and isoleucine in plants is inhibited by herbicides comprising imidazolinones. A mutant gene encoding imidazolinone-resistant ALS has been isolated from an imidazolinone-resistant Arabidopsis thaliana (GH-90) and stably maintained in a plasmid pKS1. When compared with the gene coding for imidazolinone-sensitive ALS, the imidazolinone-resistant ALS gene contains a point mutation, wherein adenosine is substituted for guanosine at nucleotide 1958, resulting in the substitution of asparagine for serine at amino acid residue 653. The mutant ALS gene can be used to impart imidazolinone resistance to a crop plant; thereby permitting the utilization of the imidazolinone or analogous herbicide as a single application at a concentration which ensures the complete or substantially complete killing of weeds, while leaving the transgenic crop plant essentially undamaged.Type: GrantFiled: August 20, 1998Date of Patent: May 1, 2001Assignee: Louisiana State University Board of Supervisors a Governing body of Louisiana State University Agricultural and Mechancial CollegeInventors: Kanagasabapathi Sathasivan, Norimoto Murai

Patent number: RE37768Abstract: Murine monoclonal antibodies directed against a novel outer membrane protein (OMP) of Haemophilus influenzae have been isolated and characterized. The gene encoding of the outer membrane protein has also been isolated and characterized. Portions of the DNA sequence of the 15 kD OMP gene are useful as probes to diagnose the presence of Haemophilus influenzae in samples. These DNA's also make available polypeptide sequences of immunoreactive epitopes encoded within the gene, thus permitting the production of polypeptides which are useful as standards or reagents in diagnostic tests and/or as components of vaccines. Monoclonal antibodies directed against epitopes of the 15 kD OMP are also useful for diagnostic tests and as therapeutic agents for passive immunization.Type: GrantFiled: April 2, 1998Date of Patent: June 25, 2002Inventors: Bernard R. Brodeur, Josee Hamel, Robert S. Munson, Jr., Susan Grass
