Publication number: 20090300795Abstract: The invention relates to nucleic acid, which codes for an autoactivated resistance protein for creating a resistance to pathogens in plants, characterized in that the nucleic acid has a limited portion of an NBS-LRR resistance gene, which extends from the 5?-end of the coded region of the NBS-LRR resistance downstream to the beginning of the NBS domain of the NBS-LRR resistance gene, the NBS-LRR resistance gene not being a TIR-NBS-LRR resistance gene.Type: ApplicationFiled: June 2, 2006Publication date: December 3, 2009Applicant: KWS SAAT AGInventor: Dietmar Juergen Stahl
-
Publication number: 20090188006Abstract: The invention relates to a pathogen-inducible synthetic promoter which is suitable for regulating the transcription of a nucleic acid, and includes a minimal promoter, characterized in that the minimal promoter includes a sequence motif a) dbrmwa or b) twcccmt which is disposed downstream from a TATA region and in front of a transcription starting point which is located on the minimal promoter and at which transcription of the nucleic acid to be regulated starts.Type: ApplicationFiled: June 16, 2007Publication date: July 23, 2009Applicant: KWS SAAT AGInventor: Klaus Schmidt

Patent number: 7557268Abstract: Promoters which increase the pathogen-inducibility of genes in plants, preferably in sugar beets, rape, potatoes, corn, soybeans, wheat, rice, rye, barley, cotton and sunflower. The promoters are characterized in that they lead to the rapid local expression of the gene respectively under the control thereof in different organs and tissues of transgenic plants such as leaves, shoots and/or roots, after having been infected by a pathogen or wounded. This attribute makes these sequences ideal for use as a regulation element for the controlled expression of antifungal compounds and thus for developing fungus-resistant plants.Type: GrantFiled: May 19, 2000Date of Patent: July 7, 2009Assignee: KWS SAAT AGInventor: Dietmar Jürgen Stahl
-
Patent number: 7335816Abstract: The invention relates to glyphosate tolerant sugar beet plants, plant material and seeds. It is the object of the invention to provide a transgenic sugar beet plant event that shows a high level of tolerance against glyphosate, but is not impaired in other important agronomic properties such as growth, yield, quality, pathogen resistance etc.Type: GrantFiled: February 28, 2003Date of Patent: February 26, 2008Assignee: KWS SAAT AGInventors: Josef Kraus, Elke Sauerbrey, Reinhard Nehls, Andreas Loock, Rudolf Jansen

Patent number: 6809243Abstract: An inbred corn line, designated KW4636, is disclosed. The invention relates to the seeds of inbred corn line KW4636, to the plants of inbred corn line KW4636 and to methods for producing a corn plant, either inbred or hybrid, by crossing the inbred line KW4636 with itself or another corn line. The invention further relates to methods for producing a corn plant containing in its genetic material one or more transgenes from said corn line KW4636 and to the transgenic plants produced by that method.Type: GrantFiled: May 14, 2001Date of Patent: October 26, 2004Assignee: KWS SAAT AGInventor: Jerry L.

Patent number: 6449869Abstract: Device and method for drying a pourable products. The device includes a rotor chamber in which a rotor is arranged with a vertical rotor axis. The rotor has a central horizontal surface and, at least in its radially outer third, a conical shell which is inclined to the axis of rotation by 20° to 70°, in such a way that the end face of the conical shell has the largest diameter and is located at the top. The conical shell has, at least partially, sheet-like gas passages in the form of perforations or screens. The method for drying pourable products provides for dry gas to be fed in a sheet like manner to the products to be dried during the radially peripheral circulation of the products without the products being swirled up and being exposed to unacceptable compressive, concussive and/or frictional loads.Type: GrantFiled: May 24, 2000Date of Patent: September 17, 2002Assignees: Glatt Systemtechnik Dresden GmbH, KWS Saat AGInventors: Frank Bretschneider, Bruno Peter, Jürgen Brückner

Patent number: 6354728Abstract: Device for producing a pourable product with a guide vane therein and method for using the device. The device includes a rotor chamber in which a rotor is arranged with a vertical rotor axis. The rotor has, at least in its radially outer third, the shape of a conical shell. Guide vanes for circulating starting materials or the product are arranged statically on an inner wall of the rotor chamber above the plane of the upper edge of the rotor. The guide vanes have, in cross section to the rotor axis, essentially the shape of a segment of a circle or spiral. The inner ends of the guide vanes lie approximately in the middle part of the rotor radius. The conical shell may have at least partially sheet-like gas passages in the form of perforations or screens. The device is used for producing pourable products.Type: GrantFiled: May 24, 2000Date of Patent: March 12, 2002Assignees: Glatt Systemtechnik Dresden GmbH, Kws Saat AGInventors: Frank Bretschneider, Bruno Peter, Jürgen Bruckner

Patent number: 6127608Abstract: This invention is in the field of corn breeding, specifically relating to a dent corn inbred KW7791 and a resultant single cross dent corn hybrid designated as 6060Bt. Inbred KW7791 is especially bred for the north central United States and has demonstrated through the heterosis/hybrid vigor displayed in several single cross hybrids of which KW7791 is one of the parents, that it has superior general combining ability. Hybrid 6060Bt is a single cross hybrid developed by using KW7791 as one of the parents. Hybrid 6060Bt is a variety having superior agronomic performance that was especially bred for the north central United States.Type: GrantFiled: January 5, 1999Date of Patent: October 3, 2000Assignee: KWS SAAT AGInventor: Harold A.
