Patent number: 6563026Abstract: This invention relates to transgenic winter oilseed rape (WOSR) plants, plant material and seeds, wherein harboring a specific transformation event. It pertains to winter oilseed rape plants, more particularly to a pair of winter oilseed rape plants, which is particularly suited for the production of hybrid seed. More specifically, one plant is wherein being male-sterile, due to the presence in its genome of a male sterility gene, while the other is wherein carrying a fertility-restorer gene, capable of preventing the activity of the male-sterility gene. The invention further provides a method for producing hybrid seed, a process for producing a transgenic WOSR plant oil or plant, and a method to identify a transgenic plant, cell or tissue. A kit for identifying the transgenic plants comparing the elite event of the present invention is also described.Type: GrantFiled: December 8, 2000Date of Patent: May 13, 2003Assignee: Aventis CropScience N.V.Inventors: Greta De Both, Marc De Beuckeleer

Patent number: 6448226Abstract: The present invention relates to transformed plants and plant cells comprising DNA molecules encoding Bacillus thuringiensis proteins with insecticidal activity. The invention relates more particularly to transformed plants and plant cells comprising DNA molecules encoding the protease resistant toxins BTS02618Aa or BTS02618Ab, as well as to methods of rendering plants or plant cells resistant to insects using these DNA molecules.Type: GrantFiled: December 23, 1999Date of Patent: September 10, 2002Assignee: Aventis CropScience N.V.Inventors: Bart Lambert, Stefan Jansens, Katrien Van Audenhove, Marnix Peferoen, Jeroen Van Rie, Roel Van Aarssen

Patent number: 6372967Abstract: A plant, the nuclear genome of which is transformed with a foreign DNA sequence encoding a protein or polypeptide which disrupts the metabolism, functioning and/or development of stamen cells of the plant, said foreign DNA under the control of a stamen-specific promoter. The foreign DNA sequence also optionally encodes a marker.Type: GrantFiled: March 5, 1993Date of Patent: April 16, 2002Assignee: Aventis CropScience N.V.Inventors: Celestina Mariani, Jan Leemans, Willy De Greef, Marc De Beuckeleer

Patent number: 6372963Abstract: A process for integrating a DNA fragment into the genome of a cell of a monocotyledonous plant, the process comprising the steps of: 1) incubating, prior to contacting with the DNA fragment, a culture of untransformed monocotyledonous plant cells on a medium comprising a plant phenolic compound, for a period of time sufficient to stimulate cell division and enhance competence for integration of foreign DNA; and 2) contacting the untransformed cells with the DNA fragment under conditions in which the DNA fragment is taken up by the untransformed cells and is stably integrated in the genome of the untransformed cells, to generate transformed cells.Type: GrantFiled: January 10, 2000Date of Patent: April 16, 2002Assignee: Aventis CropScience N.V.Inventor: Kathleen D'Halluin

Patent number: 6344602Abstract: A plant having in the nuclear genome of its cells foreign DNA comprising i) a male-sterility gene comprising a male-sterility DNA encoding a sterility RNA, protein or polypeptide which, when produced or overproduced in a stamen cell of the plant, significantly disturbs the metabolism, functioning and/or development of the stamen cell, and, a sterility promoter directing expression of the male-sterility DNA selectively in specific stamen cells of said plant, the male-sterility DNA being in the same transcriptional unit as, and under the control of, the sterility promoter, and ii) a coregulating gene comprising a coregulating DNA encoding a coregulating RNA, protein or polypeptide which, when produced in plant cells wherein said sterility RNA, protein or polypeptide is produced, prevents the activity of said sterility RNA, protein or polypeptide, and a coregulating promoter which is selected from the group consisting of a promoter directing expression of said coregulating DNA in non-stamen cells of said plant,Type: GrantFiled: December 10, 1999Date of Patent: February 5, 2002Assignee: Aventis CropScience N.V.Inventors: Frank Michiels, Johan Botterman, Marc Cornelissen

Patent number: 6107546Abstract: Novel transformation vectors containing novel chimeric genes allow the introduction of exogenous DNA fragments coding for truncated Bacillus thuringiensis Bt2 polypeptide toxins and expression of the chimeric gene in plant cells and their progeny after Integration into the plant cell genome. Transformed plant cells and their progeny exhibit stably inherited polypeptide toxin expression useful for protecting said plant cells and their progeny against Lepidopteron insect pests and in controlling said insect pests.Type: GrantFiled: June 5, 1995Date of Patent: August 22, 2000Assignee: Aventis CropScience N.V.Inventors: Henri Marcel Jozef De Greve, Maria Benita Leonor Fernandez Salgado, Marc Charles Ernest Van Montagu, Mark Albert Vaeck, Marcus Florent Oscar Zabeau, Jan Jozef August Leemans, Hermanus Fransiscus Paulus Hofte
